System on Chip vs Processor on Chip
SoC stands for System on Chip which is a small chip containing all required components and circuits of a particular system. PoC stands for Processor on Chip which consists of a few processors. Usually in the case of processors on chip, the processors are mounted on the chipset. Mostly microprocessor is referred to as a processor on the chip. In this article, we are going to see the basic differences between SoC and PoC.
System on chip (SoC)
The Blocks of SoC contain memory, oscillator, voltage regulator, ADC, and DAC, processor, power management unit, USB, and UART. Processor is the heart of SoC usually SoC has multiple co-processors. It can be a microcontroller, microprocessor, or DSP. SoC contains memory for storage. It may have RAM, ROM, EEPROM, or Flash memory. SoC also has GPU. Universal Asynchronous Receiver Transmitter (UART) is included in SoC which is used to transmit or receive serial data. Voltage regulators, oscillators, clocks, and ADC/DAC are also part of SoC.
Advantages of SoC
- SoC is small in size and includes more features and functions.
- Power consumption is low in SoC.
- It is cost-effective.
Disadvantages of SoC
- Designing process of SoC is time-consuming.
- Limited visibility is also a disadvantage of SoC.
Applications of SoC
- Used in smartwatches, smartphones, tablets, and computers, etc.
Processor on Chip (PoC)
Processor on Chip are usually referred to as processors that are used on the chipset most of the time a microprocessor is used as a processor on the chip. Some of the advantages of the microprocessor are it is available at a very low cost in the market, its size is small in size and highly portable in nature, and also it is versatile and reliable too.
Advantages of PoC
- PoC is Portable in nature.
- They are versatile we can easily remove or attach them.
- Power consumption is low in PoC.
Disadvantages of PoC
- Complex interface or structure is one of the disadvantages.
- Overheating is also a disadvantage of PoCs.
Applications of PoC
- Electronic products like toys, cameras, robots, washing machine,s etc.
