What is SoC?
What is SoC? What function does SoC really serve in a gadget? A SoC is a system that integrates all the components like graphics processor, bus controller, memory, power circuits and most importantly, the CPU; all onto a single chip. A single SoC is enough to run entire devices like computers, mobiles and laptops! The biggest advantage of an SoC is that the high level of integration and shorter wiring considerably reduces its power consumption. Also, cutting down the number of chips guarantees lesser price with the same amount of features! However, there is the slight issue of flexibility when you compare system on chip. The RAM, GPU or CPU cannot be replaced as and when required. A typical SoC consists of the following components-
- Operating System
- RAM and ROM
- External Interfaces like USB, USART, I2C
- Digital Signal Proceccor
As a system-on-chip incorporates both hardware and software components, it operates on lower power, requires less space than a traditional CPU, has a better performance, and is much more reliable than multicore systems. However, some of its challenges include architecture costs, complex debugging and longer manufacturing time. Most SoCs are found in portable devices such as tablets and smartphones.
