Mobile computing based SoCs always bundle processors, memories, on-chip caches, wireless networking capabilities and often digital camera hardware and firmware. Mobile computing System on a chip AMD Élan SC450 in Nokia 9000 Communicator Often embedded SoCs target the internet of things, industrial internet of things and edge computing markets. Applications include AI acceleration, embedded machine vision, data collection, telemetry, vector processing and ambient intelligence. Tighter system integration offers better reliability and mean time between failure, and SoCs offer more advanced functionality and computing power than microcontrollers. Where previously only microcontrollers could be used, SoCs are rising to prominence in the embedded systems market. However, they are typically used in mobile computing such as tablets, smartphones, smartwatches and netbooks as well as embedded systems and in applications where previously microcontrollers would be used. SoCs can be applied to any computing task. Specialized application-specific integrated circuit SoCs designed for specific applications that do not fit into the above two categories.SoCs built around a microprocessor, often found in mobile phones.In general, there are three distinguishable types of SoCs: Types Microcontroller-based system on a chip They are also commonly used in embedded systems such as WiFi routers and the Internet of things. SoCs are very common in the mobile computing (such as in smartphones and tablet computers) and edge computing markets. SoCs can be viewed as part of a larger trend towards embedded computing and hardware acceleration. For these reasons, there has been a general trend towards tighter integration of components in the computer hardware industry, in part due to the influence of SoCs and lessons learned from the mobile and embedded computing markets. By definition, SoC designs are fully or nearly fully integrated across different component modules. This comes at the cost of reduced replaceability of components. For an overview of integrating system components, see system integration.Ĭompared to a multi-chip architecture, an SoC with equivalent functionality will have increased performance and reduced power consumption as well as a smaller semiconductor die area. Similar to how a microcontroller integrates a microprocessor with peripheral circuits and memory, an SoC can be seen as integrating a microcontroller with even more advanced peripherals. An SoC will typically integrate a CPU, graphics and memory interfaces, secondary storage and USB connectivity, I/O interfaces on a single chip, whereas a motherboard would connect these modules as discrete components or expansion cards.Īn 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. Whereas a motherboard houses and connects detachable or replaceable components, SoCs integrate all of these components into a single integrated circuit. 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 board. Additionally, SoCs may use separate wireless modems. Higher-performance SoCs are often paired with dedicated and physically separate memory and secondary storage (such as LPDDR and eUFS or eMMC, respectively) chips, that may be layered on top of the SoC in what's known as a package on package (PoP) configuration, or be placed close to the SoC. SoCs may contain digital, and also analog, mixed-signal, and often radio frequency signal processing functions (otherwise it may be considered on a discrete application processor). These components almost always include on-chip central processing unit (CPU), memory interfaces, input/output devices, input/output interfaces, and secondary storage interfaces, often alongside other components such as radio modems and a graphics processing unit (GPU) – all on a single substrate or microchip.
