Integrated circuit that incorporates the components of a computer

A system on a chip (SoC; es-oh-SEE or sock ^{[nb ane]}) is an integrated circuit (also known as a "chip") that integrates all or most components of a estimator or other electronic system. These components nearly always include a key processing unit (CPU), memory, input/output ports and secondary storage, frequently alongside other components such as radio modems and a graphics processing unit (GPU) – all on a single substrate or microchip.^[1] Information technology may comprise digital, analog, mixed-point, and often radio frequency signal processing functions (otherwise it is considered only an application processor).

College-functioning SoCs are ofttimes paired with dedicated and physically dissever retentivity and secondary storage (almost always LPDDR and eUFS or eMMC, respectively) chips, that may exist layered on top of the SoC in what's known as a package on parcel (Popular) configuration, or be placed close to the SoC. Additionally, SoCs may utilize dissever wireless modems.^[ii]

SoCs are in contrast to the common traditional motherboard-based PC architecture, which separates components based on function and connects them through a central interfacing circuit lath.^{[nb 2]} Whereas a motherboard houses and connects detachable or replaceable components, SoCs integrate all of these components into a single integrated circuit. An SoC will typically integrate a CPU, graphics and memory interfaces,^{[nb iii]} difficult-deejay and USB connectivity,^{[nb four]} random-access and read-only memories and secondary storage and/or their controllers on a single excursion dice, whereas a motherboard would connect these modules equally discrete components or expansion cards.

An SoC integrates a microcontroller, microprocessor or perhaps several processor cores with peripherals like a GPU, Wi-Fi and cellular network radio modems, and/or one or more coprocessors. Similar to how a microcontroller integrates a microprocessor with peripheral circuits and retentivity, an SoC can be seen as integrating a microcontroller with even more advanced peripherals. For an overview of integrating system components, meet system integration.

More than tightly integrated reckoner system designs ameliorate operation and reduce power consumption equally well equally semiconductor die area than multi-bit designs with equivalent functionality. This comes at the cost of reduced replaceability of components. By definition, SoC designs are fully or nearly fully integrated across different component modules. For these reasons, in that location has been a general trend towards tighter integration of components in the figurer hardware industry, in function due to the influence of SoCs and lessons learned from the mobile and embedded computing markets. SoCs tin can exist viewed as office of a larger trend towards embedded computing and hardware acceleration.

SoCs are very common in the mobile computing (such as in smartphones and tablet computers) and border computing markets.^{[3] [4]} They are also commonly used in embedded systems such equally WiFi routers and the Internet of Things.

Types [edit]

In general, there are three distinguishable types of SoCs:

• SoCs congenital around a microcontroller,
• SoCs built around a microprocessor, frequently found in mobile phones;
• Specialized application-specific integrated circuit SoCs designed for specific applications that do not fit into the above two categories

Applications [edit]

SoCs tin exist applied to any computing task. However, they are typically used in mobile computing such as tablets, smartphones, smartwatches and netbooks every bit well as embedded systems and in applications where previously microcontrollers would be used.

Embedded systems [edit]

Where previously only microcontrollers could be used, SoCs are rising to prominence in the embedded systems market. Tighter organization integration offers meliorate reliability and mean time between failure, and SoCs offer more than advanced functionality and computing power than microcontrollers.^[5] Applications include AI dispatch, embedded machine vision,^[6] data drove, telemetry, vector processing and ambience intelligence. Often embedded SoCs target the net of things, industrial cyberspace of things and edge computing markets.

Mobile calculating [edit]

Mobile computing based SoCs ever bundle processors, memories, on-chip caches, wireless networking capabilities and oft digital camera hardware and firmware. With increasing retentivity sizes, high end SoCs will often have no memory and flash storage and instead, the retentiveness and flash retentivity volition be placed right adjacent to, or higher up (package on package), the SoC.^[vii] Some examples of mobile computing SoCs include:

• Samsung Electronics: list, typically based on ARM
  • Exynos, used mainly by Samsung's Galaxy series of smartphones
• Qualcomm:
  • Snapdragon (list), used in many LG, Xiaomi, Google Pixel, HTC and Samsung Galaxy smartphones. In 2018, Snapdragon SoCs are being used as the backbone of laptop computers running Windows 10, marketed as "Always Connected PCs".^{[8] [ix]}

Personal computers [edit]

In 1992, Acorn Computers produced the A3010, A3020 and A4000 range of personal computers with the ARM250 SoC. Information technology combined the original Acorn ARM2 processor with a retentivity controller (MEMC), video controller (VIDC), and I/O controller (IOC). In previous Acorn ARM-powered computers, these were four discrete chips. The ARM7500 bit was their second-generation SoC, based on the ARM700, VIDC20 and IOMD controllers, and was widely licensed in embedded devices such every bit set up-top-boxes, as well as later Acorn personal computers.

SoCs are being applied to mainstream personal computers as of 2018.^[viii] They are specially applied to laptops and tablet PCs. Tablet and laptop manufacturers have learned lessons from embedded systems and smartphone markets about reduced power consumption, better performance and reliability from tighter integration of hardware and firmware modules, and LTE and other wireless network communications integrated on chip (integrated network interface controllers).^[10]

ARM-based:

• Qualcomm Snapdragon^[9]
• ARM250
• ARM7500(FE)
• Apple M1

x86-based:

• Intel Core CULV

Structure [edit]

An SoC consists of hardware functional units, including microprocessors that run software lawmaking, likewise as a communications subsystem to connect, control, direct and interface between these functional modules.

Functional components [edit]

Processor cores [edit]

An SoC must accept at least one processor cadre, but typically an SoC has more than one core. Processor cores tin be a microcontroller, microprocessor (μP),^[11] digital signal processor (DSP) or awarding-specific instruction set processor (ASIP) core.^[12] ASIPs accept instruction sets that are customized for an application domain and designed to be more efficient than full general-purpose instructions for a specific blazon of workload. Multiprocessor SoCs have more than 1 processor core by definition.

Whether single-core, multi-core or manycore, SoC processor cores typically employ RISC instruction set architectures. RISC architectures are advantageous over CISC processors for SoCs because they require less digital logic, and therefore less power and area on board, and in the embedded and mobile computing markets, expanse and power are often highly constrained. In particular, SoC processor cores often use the ARM architecture because it is a soft processor specified as an IP cadre and is more than power efficient than x86.^[11]

Memory [edit]

SoCs must have semiconductor retentiveness blocks to perform their computation, as practice microcontrollers and other embedded systems. Depending on the application, SoC retention may course a memory hierarchy and cache hierarchy. In the mobile computing market, this is mutual, only in many low-power embedded microcontrollers, this is non necessary. Retentiveness technologies for SoCs include read-just retention (ROM), random-admission retention (RAM), Electrically Erasable Programmable ROM (EEPROM) and flash memory.^[11] Equally in other computer systems, RAM can be subdivided into relatively faster but more expensive static RAM (SRAM) and the slower just cheaper dynamic RAM (DRAM). When an SoC has a cache hierarchy, SRAM will commonly exist used to implement processor registers and cores' L1 caches whereas DRAM will be used for lower levels of the cache hierarchy including main retentivity. "Main retention" may be specific to a single processor (which tin be multi-core) when the SoC has multiple processors, in which case it is distributed retentivity and must be sent via § Intermodule advice on-flake to be accessed by a dissimilar processor.^[12] For further discussion of multi-processing memory issues, see cache coherence and retentiveness latency.

Interfaces [edit]

SoCs include external interfaces, typically for communication protocols. These are often based upon manufacture standards such equally USB, FireWire, Ethernet, USART, SPI, HDMI, I²C, etc. These interfaces will differ co-ordinate to the intended application. Wireless networking protocols such as Wi-Fi, Bluetooth, 6LoWPAN and near-field communication may as well be supported.

When needed, SoCs include analog interfaces including analog-to-digital and digital-to-analog converters, oft for point processing. These may be able to interface with unlike types of sensors or actuators, including smart transducers. They may interface with application-specific modules or shields.^{[nb 5]} Or they may be internal to the SoC, such as if an analog sensor is built in to the SoC and its readings must exist converted to digital signals for mathematical processing.

Digital signal processors [edit]

Digital signal processor (DSP) cores are frequently included on SoCs. They perform signal processing operations in SoCs for sensors, actuators, data collection, information assay and multimedia processing. DSP cores typically feature very long education give-and-take (VLIW) and single instruction, multiple data (SIMD) teaching set architectures, and are therefore highly amenable to exploiting education-level parallelism through parallel processing and superscalar execution.^{[12] : iv} DSP cores most often feature awarding-specific instructions, and as such are typically application-specific pedagogy-set up processors (ASIP). Such application-specific instructions stand for to defended hardware functional units that compute those instructions.

Typical DSP instructions include multiply-accumulate, Fast Fourier transform, fused multiply-add, and convolutions.

Other [edit]

As with other estimator systems, SoCs require timing sources to generate clock signals, command execution of SoC functions and provide time context to bespeak processing applications of the SoC, if needed. Pop fourth dimension sources are crystal oscillators and phase-locked loops.

SoC peripherals including counter-timers, real-time timers and power-on reset generators. SoCs also include voltage regulators and ability direction circuits.

Intermodule advice [edit]

SoCs comprise many execution units. These units must often ship data and instructions back and forth. Considering of this, all but the most trivial SoCs require communications subsystems. Originally, as with other microcomputer technologies, data omnibus architectures were used, but recently designs based on sparse intercommunication networks known as networks-on-chip (NoC) accept risen to prominence and are forecast to overtake passenger vehicle architectures for SoC pattern in the most future.^[13]

Bus-based advice [edit]

Historically, a shared global figurer bus typically connected the different components, as well called "blocks" of the SoC.^[13] A very mutual bus for SoC communications is ARM'southward royalty-gratuitous Advanced Microcontroller Bus Architecture (AMBA) standard.

Direct retentivity access controllers route data directly between external interfaces and SoC memory, bypassing the CPU or control unit, thereby increasing the data throughput of the SoC. This is similar to some device drivers of peripherals on component-based multi-chip module PC architectures.

Computer buses are limited in scalability, supporting only upwardly to tens of cores (multicore) on a single chip.^{[13] : xiii} Wire filibuster is non scalable due to continued miniaturization, organisation performance does non calibration with the number of cores attached, the SoC's operating frequency must subtract with each additional cadre fastened for power to be sustainable, and long wires consume large amounts of electrical power. These challenges are prohibitive to supporting manycore systems on chip.^{[13] : thirteen}

Network on a fleck [edit]

In the late 2010s, a tendency of SoCs implementing communications subsystems in terms of a network-similar topology instead of bus-based protocols has emerged. A trend towards more processor cores on SoCs has acquired on-chip communication efficiency to get one of the central factors in determining the overall system functioning and cost.^{[xiii] : thirteen} This has led to the emergence of interconnection networks with router-based packet switching known equally "networks on flake" (NoCs) to overcome the bottlenecks of bus-based networks.^{[thirteen] : xiii}

Networks-on-flake have advantages including destination- and application-specific routing, greater power efficiency and reduced possibility of autobus contention. Network-on-bit architectures take inspiration from communication protocols like TCP and the Cyberspace protocol suite for on-chip communication,^[13] although they typically have fewer network layers. Optimal network-on-chip network architectures are an ongoing area of much inquiry interest. NoC architectures range from traditional distributed calculating network topologies such equally torus, hypercube, meshes and tree networks to genetic algorithm scheduling to randomized algorithms such as random walks with branching and randomized fourth dimension to live (TTL).

Many SoC researchers consider NoC architectures to be the time to come of SoC design because they take been shown to efficiently meet power and throughput needs of SoC designs. Current NoC architectures are two-dimensional. 2D IC design has limited floorplanning choices as the number of cores in SoCs increase, so as three-dimensional integrated circuits (3DICs) emerge, SoC designers are looking towards building 3-dimensional on-scrap networks known as 3DNoCs.^[13]

Design flow [edit]

A system on a bit consists of both the hardware, described in § Construction, and the software decision-making the microcontroller, microprocessor or digital indicate processor cores, peripherals and interfaces. The blueprint flow for an SoC aims to develop this hardware and software at the same fourth dimension, too known as architectural co-design. The design menstruation must besides accept into account optimizations (§ Optimization goals) and constraints.

Almost SoCs are developed from pre-qualified hardware component IP core specifications for the hardware elements and execution units, collectively "blocks", described above, together with software device drivers that may control their operation. Of particular importance are the protocol stacks that drive industry-standard interfaces like USB. The hardware blocks are put together using computer-aided design tools, specifically electronic pattern automation tools; the software modules are integrated using a software integrated development environment.

SoCs components are also often designed in high-level programming languages such every bit C++, MATLAB or SystemC and converted to RTL designs through high-level synthesis (HLS) tools such as C to HDL or flow to HDL.^[fourteen] HLS products called "algorithmic synthesis" allow designers to use C++ to model and synthesize system, circuit, software and verification levels all in one high level language commonly known to figurer engineers in a manner independent of time scales, which are typically specified in HDL.^[xv] Other components can remain software and be compiled and embedded onto soft-core processors included in the SoC every bit modules in HDL equally IP cores.

Once the architecture of the SoC has been defined, any new hardware elements are written in an abstruse hardware description language termed annals transfer level (RTL) which defines the excursion behavior, or synthesized into RTL from a loftier level linguistic communication through high-level synthesis. These elements are continued together in a hardware description language to create the full SoC design. The logic specified to connect these components and convert between possibly different interfaces provided past unlike vendors is chosen glue logic.

Pattern verification [edit]

Chips are verified for validation correctness before being sent to a semiconductor foundry. This process is called functional verification and it accounts for a pregnant portion of the fourth dimension and free energy expended in the chip pattern life cycle, ofttimes quoted as lxx%.^{[16] [17]} With the growing complexity of fries, hardware verification languages like SystemVerilog, SystemC, e, and OpenVera are being used. Bugs found in the verification stage are reported to the designer.

Traditionally, engineers have employed simulation dispatch, emulation or prototyping on reprogrammable hardware to verify and debug hardware and software for SoC designs prior to the finalization of the design, known as tape-out. Field-programmable gate arrays (FPGAs) are favored for prototyping SoCs because FPGA prototypes are reprogrammable, allow debugging and are more than flexible than application-specific integrated circuits (ASICs).^{[18] [19]}

With loftier capacity and fast compilation time, simulation acceleration and emulation are powerful technologies that provide wide visibility into systems. Both technologies, even so, operate slowly, on the order of MHz, which may be significantly slower – up to 100 times slower – than the SoC's operating frequency. Acceleration and emulation boxes are also very large and expensive at over U.s.$1 1000000.^{[ citation needed ]}

FPGA prototypes, in dissimilarity, use FPGAs directly to enable engineers to validate and exam at, or close to, a system's total operating frequency with real-world stimuli. Tools such as Certus^[20] are used to insert probes in the FPGA RTL that make signals available for observation. This is used to debug hardware, firmware and software interactions beyond multiple FPGAs with capabilities similar to a logic analyzer.

In parallel, the hardware elements are grouped and passed through a process of logic synthesis, during which performance constraints, such as operational frequency and expected signal delays, are applied. This generates an output known as a netlist describing the design as a physical excursion and its interconnections. These netlists are combined with the glue logic connecting the components to produce the schematic description of the SoC as a excursion which tin can be printed onto a scrap. This procedure is known as place and route and precedes tape-out in the event that the SoCs are produced as application-specific integrated circuits (ASIC).

Optimization goals [edit]

SoCs must optimize power use, area on die, communication, positioning for locality betwixt modular units and other factors. Optimization is necessarily a blueprint goal of SoCs. If optimization was not necessary, the engineers would use a multi-scrap module architecture without bookkeeping for the surface area utilization, power consumption or performance of the system to the same extent.

Mutual optimization targets for SoC designs follow, with explanations of each. In full general, optimizing any of these quantities may be a hard combinatorial optimization problem, and can indeed be NP-hard adequately easily. Therefore, sophisticated optimization algorithms are often required and it may exist practical to apply approximation algorithms or heuristics in some cases. Additionally, most SoC designs comprise multiple variables to optimize simultaneously, so Pareto efficient solutions are sought afterwards in SoC design. Oftentimes the goals of optimizing some of these quantities are directly at odds, further adding complication to design optimization of SoCs and introducing trade-offs in system blueprint.

For broader coverage of trade-offs and requirements analysis, see requirements engineering science.

Targets [edit]

Power consumption [edit]

SoCs are optimized to minimize the electrical ability used to perform the SoC's functions. Almost SoCs must use low ability. SoC systems often require long battery life (such as smartphones), tin can potentially spending months or years without a ability source needing to maintain autonomous function, and ofttimes are limited in ability apply by a high number of embedded SoCs being networked together in an area. Additionally, energy costs can exist high and conserving energy will reduce the full toll of ownership of the SoC. Finally, waste heat from loftier energy consumption can damage other excursion components if likewise much heat is dissipated, giving another pragmatic reason to conserve energy. The amount of free energy used in a excursion is the integral of power consumed with respect to time, and the boilerplate charge per unit of ability consumption is the product of electric current by voltage. Equivalently, past Ohm's law, power is electric current squared times resistance or voltage squared divided by resistance:

$${\displaystyle P=Iv={\frac {V^{2}}{R}}={I^{2}}{R}}$$

SoCs are oftentimes embedded in portable devices such every bit smartphones, GPS navigation devices, digital watches (including smartwatches) and netbooks. Customers want long battery lives for mobile computing devices, another reason that ability consumption must exist minimized in SoCs. Multimedia applications are often executed on these devices, including video games, video streaming, image processing; all of which have grown in computational complication in recent years with user demands and expectations for higher-quality multimedia. Computation is more than demanding as expectations move towards 3D video at high resolution with multiple standards, so SoCs performing multimedia tasks must be computationally capable platform while being low power to run off a standard mobile battery.^{[12] : 3}

Performance per watt [edit]

SoCs are optimized to maximize power efficiency in functioning per watt: maximize the functioning of the SoC given a budget of power usage. Many applications such every bit border calculating, distributed processing and ambient intelligence require a certain level of computational performance, simply power is limited in about SoC environments. The ARM architecture has greater performance per watt than x86 in embedded systems, and then it is preferred over x86 for virtually SoC applications requiring an embedded processor.

Waste rut [edit]

SoC designs are optimized to minimize waste oestrus output on the chip. Every bit with other integrated circuits, oestrus generated due to high power density are the clogging to further miniaturization of components.^{[21] : 1} The ability densities of loftier speed integrated circuits, particularly microprocessors and including SoCs, have go highly uneven. Too much waste product heat can damage circuits and erode reliability of the circuit over time. Loftier temperatures and thermal stress negatively touch on reliability, stress migration, decreased hateful time between failures, electromigration, wire bonding, metastability and other performance degradation of the SoC over time.^{[21] : 2–9}

In particular, most SoCs are in a small physical surface area or volume and therefore the effects of waste estrus are compounded considering in that location is little room for it to diffuse out of the system. Considering of loftier transistor counts on modern devices, oftentimes a layout of sufficient throughput and loftier transistor density is physically realizable from fabrication processes but would result in unacceptably loftier amounts of heat in the circuit'due south volume.^{[21] : 1}

These thermal effects force SoC and other scrap designers to apply conservative design margins, creating less performant devices to mitigate the risk of catastrophic failure. Due to increased transistor densities as length scales get smaller, each process generation produces more rut output than the final. Compounding this problem, SoC architectures are commonly heterogeneous, creating spatially inhomogeneous heat fluxes, which cannot be finer mitigated by uniform passive cooling.^{[21] : 1}

Throughput [edit]

This section needs expansion. You can aid past calculation to it. (October 2018)

SoCs are optimized to maximize computational and communications throughput.

Latency [edit]

This department needs expansion. Y'all can help past adding to it. (Oct 2018)

SoCs are optimized to minimize latency for some or all of their functions. This can exist accomplished by laying out elements with proper proximity and locality to each-other to minimize the interconnection delays and maximize the speed at which data is communicated between modules, functional units and memories. In full general, optimizing to minimize latency is an NP-complete problem equivalent to the boolean satisfiability trouble.

For tasks running on processor cores, latency and throughput can be improved with job scheduling. Some tasks run in application-specific hardware units, however, and even task scheduling may non be sufficient to optimize all software-based tasks to see timing and throughput constraints.

Methodologies [edit]

This section needs expansion. You tin aid by adding to it. (October 2018)

Systems on chip are modeled with standard hardware verification and validation techniques, but additional techniques are used to model and optimize SoC pattern alternatives to brand the system optimal with respect to multiple-criteria decision analysis on the above optimization targets.

Job scheduling [edit]

Task scheduling is an important activity in whatever computer system with multiple processes or threads sharing a single processor core. It is of import to reduce § Latency and increase § Throughput for embedded software running on an SoC'southward § Processor cores. Not every important computing activity in a SoC is performed in software running on on-chip processors, but scheduling tin can drastically improve performance of software-based tasks and other tasks involving shared resources.

SoCs oft schedule tasks according to network scheduling and randomized scheduling algorithms.

Pipelining [edit]

Hardware and software tasks are often pipelined in processor design. Pipelining is an important principle for speedup in figurer architecture. They are often used in GPUs (graphics pipeline) and RISC processors (evolutions of the classic RISC pipeline), but are also applied to application-specific tasks such as digital bespeak processing and multimedia manipulations in the context of SoCs.^[12]

Probabilistic modeling [edit]

SoCs are often analyzed though probabilistic models, Queueing theory § Queueing networks and Markov chains. For instance, Little's law allows SoC states and NoC buffers to be modeled every bit arrival processes and analyzed through Poisson random variables and Poisson processes.

Markov bondage [edit]

SoCs are frequently modeled with Markov bondage, both discrete fourth dimension and continuous time variants. Markov chain modeling allows asymptotic assay of the SoC's steady country distribution of power, heat, latency and other factors to allow pattern decisions to be optimized for the common case.

Fabrication [edit]

SoC chips are typically fabricated using metal–oxide–semiconductor (MOS) engineering.^[22] The netlists described higher up are used equally the basis for the physical blueprint (place and route) catamenia to convert the designers' intent into the design of the SoC. Throughout this conversion process, the design is analyzed with static timing modeling, simulation and other tools to ensure that it meets the specified operational parameters such as frequency, power consumption and dissipation, functional integrity (as described in the register transfer level code) and electrical integrity.

When all known bugs have been rectified and these have been re-verified and all physical design checks are done, the physical pattern files describing each layer of the chip are sent to the foundry's mask shop where a total ready of glass lithographic masks will exist etched. These are sent to a wafer fabrication plant to create the SoC dice earlier packaging and testing.

SoCs can exist fabricated past several technologies, including:

• Full custom ASIC
• Standard cell ASIC
• Field-programmable gate array (FPGA)

ASICs consume less power and are faster than FPGAs but cannot be reprogrammed and are expensive to manufacture. FPGA designs are more suitable for lower volume designs, just after enough units of production ASICs reduce the total toll of ownership.^[23]

SoC designs swallow less power and take a lower price and higher reliability than the multi-bit systems that they supplant. With fewer packages in the system, assembly costs are reduced as well.

However, like about very-large-scale integration (VLSI) designs, the total toll^{[ clarification needed ]} is higher for one large flake than for the same functionality distributed over several smaller chips, because of lower yields^{[ description needed ]} and higher non-recurring applied science costs.

When it is not feasible to construct an SoC for a detail application, an alternative is a arrangement in parcel (SiP) comprising a number of chips in a single package. When produced in large volumes, SoC is more price-constructive than SiP because its packaging is simpler.^[24] Another reason SiP may be preferred is waste heat may be too loftier in a SoC for a given purpose because functional components are also shut together, and in an SiP estrus will dissipate better from different functional modules since they are physically further apart.

Benchmarks [edit]
