Embedded System.

Soc ( System on Chip)

Soc is an integrated circuit (IC) that integrates all components of a computer or otherelectronic system into a single chip. It may contain digitalanalogmixed-signal, and often radio-frequency functions—all on a single chipsubstrate. SoCs are very common in the mobile electronics market because of their low power consumption. A typical application is in the area of embedded systems.

A typical SoC consists of:

bus – either proprietary or industry-standard such as the AMBA bus from ARM Holdings – connects these blocks. DMAcontrollers route data directly between external interfaces and memory, bypassing the processor core and thereby increasing the data throughput of the SoC.

Embedded System 

An embeded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts
