Just a couple of decades ago, the term system-on-chip (SOC) was only a buzzword. Nowadays, it is an essential technology that continues to advance the field of electronics. The increase in SoCs is part of the prevailing trend of increasing integration and embedded computing, allowing for computational devices that are smaller, cheaper, faster, and less power-consuming. SoCs can be found in everything from smartphones to tablets, IoT devices, routers, cameras, and more. 


What is a System-on-Chip (SoC)?

At their core, SoCs are microchips that contain all the necessary electronic circuits for a fully functional system on a single integrated circuit (IC). In other words, the CPU, internal memory, I/O ports, analog inputs and output, as well as additional application-specific circuit blocks, are all designed to be integrated on the same chip. SoCs differentiate themselves from traditional devices and PC architectures, where a separate chip is used for the CPU, GPU, RAM, and other essential functional components. 

Various SoCs are developed depending on their intended device. For example, SoCs on smartphones or other IoT devices may also incorporate Wi-Fi and cellular network modems. In the traditional approach, SoCs use shorter wiring between circuit blocks to reduce power expenditure and increase efficiencies.


SoC Components and Construction

System-on-chips, as their name implies, contain nearly all the necessary functional circuit blocks for a full system on a single chip. Generally, you will find the following components on any SoC:

  • A processor with multiple cores in the form of a microcontroller, microprocessor, digital signal processor, or application-specific instruction set processor.
  • Memory capabilities such as RAM, ROM, FLASH, EEPROM, and/or cache memory.
  • External interfaces for wired communication protocols such as HDMI, USB, FireWire, USART, SPI,  I²C, or Ethernet.
  • Wireless capabilities such as WiFi or Bluetooth and other radio frequency capabilities.
  • A Graphical Processing Unit (GPU) for accelerating specific tasks.
  • Voltage regulators, phase lock loop (PLL) control systems, built-in oscillators, timers, and analog-to-digital (ADC) converters.
  • Intrachip communication subsystems for connecting individual circuit blocks, such as Interface busses or newer intercommunication networks known as networks-on-chip (NoC).
  • Digital, analog, and mixed-signal processing circuit blocks for any sensors, actuators, data collection, and data analysis.
  • SoC capabilities powering the next generation.

Generally, engineers want to reduce energy waste, save on spending, and further miniaturize devices. With system-on-chip technology, this is possible through advanced integration methods on a single IC. 

These compact and versatile chips have powered the rise of smartphones, allowing for incredible power in a small form factor. Similarly, due to their compact and power-efficient qualities, manufacturers are incorporating SoCs into new IoT devices, embedded systems, and even automobiles. 

Furthermore, we’ve also seen a shift in SoC technology used in personal computers and laptops to further reduce power consumption and improve performance. Less circuit real estate generally results in less heat generation, less power consumption, and a lower cost of production. This has allowed more efficient device design for heat distribution, minimal latency, and accelerated data transmission. 

Because SoCs are highly specialized, they are often applied in individualized tasks. Custom SoCs are now being developed for specific applications such as enhancing machine learning, advanced AI capabilities, and high-performance computing with faster data processing. SoCs can perform multiple calculations as a distributed operation (rather than the limited parallelism offered by traditional CPUs) to further accelerate calculations. For this reason, many companies are now investing in their own development of custom SoCs to support their advanced data and signal processing needs.
