It refers to integrating all components of a computer or other electronic system into a single integrated circuit. digital, analog, mixed-signal, and often radio-frequency functions may be done by the chip all on a single chip substrate. The SoC , as compared to microcontrollers has more powerful processors, capable of running software such as Windows or Linux, which need external memory chips (flash, RAM) to be useful, and which are used with various external peripherals.
A SOC may consist of:
-One microcontroller, microprocessor or DSP core
-Timing sources including oscillators and PLL.
-Memory which maybe ROM, RAM, EEPROM and flash
-External interfaces like USB, FireWire, Ethernet, USART, SPI.
-Analog interfaces like DAC and ADC.
-Voltage regulators and power management circuits.
SoC consists of both the hardware described above, and the software that controls the microcontroller, microprocessor or DSP cores, peripherals and interfaces.The pre-qualified hardware blocks together with the software drivers that control their operation are where we start. protocol stacks driving industry-standard interfaces like USB are important. The hardware blocks are put together using CAD tools; the software modules are integrated using a software development environment.In emulation process, which is a key process, the hardware is mapped onto an emulation platform based on a field programmable gate array (FPGA) that mimics the behavior of the SoC.
several technologies used are:
The process consume less power and have a lower cost and higher reliability than the multi-chip systems that they replace. But, like most VLSI designs, the total cost is higher for one large chip than for the same functionality distributed over several smaller chips

today’s chip can contains 100M transistors .
transistor gate lengths are now in term of nano meters .
approximately every 18 months the number of transistors on a chip doubles – Moore’s law .
components connected on a Printed Circuit Board can now be integrated onto single chip .
hence the development of System-On-Chip design .
What is SoC ?
SoC not only chip, but more on “system”.
SoC = Chip + Software + Integration
The SoC chip includes:
ASIC Logics and analog circuitry
The SoC Software includes:
OS, compiler, simulator, firmware, driver, protocol stackIntegrated development environment (debugger, linker, ICE)Application interface (C/C++, assembly)
The SoC Integration includes :
System on Chip interconnection
AMBA (Advanced Microcontroller Bus Architecture) is a collection of buses from ARM for satisfying a range of different criteria.
APB (Advanced Peripheral Bus): simple strobed-access bus with minimal interface complexity. Suitable for hosting peripherals.
ASB (Advanced System Bus): a multimaster synchronous system bus.
AHB (Advanced High Performance Bus): a high- throughput synchronous system backbone. Burst transfers and split transactions.
Technological advances mean that complete systems can now be implemented on a single chip .
The benefits that this brings are significant in terms of speed , area and power .
The drawbacks are that these systems are extremely complex requiring amounts of verification .
The solution is to design and verify re-useable IP .
