What is the function of Embedded Processor

There are more than 1000 kinds of embedded processors in the world, and there are more than 30 series of popular architectures. Almost every semiconductor manufacturer now produces embedded processors.

Embedded processor is the core of embedded system and the hardware unit that controls and assists the operation of the system. The range is extremely wide, from the original 4-bit processor, the 8-bit MCU still in large-scale application, to the latest widely favored 32-bit, 64 bit embedded CPU.

Embedded processors mainly include four categories: embedded microprocessors, embedded microcontrollers, embedded DSP processors, and embedded systems on chip.

The embedded microprocessor is based on the general CPU. In application, the microprocessor is assembled on a specially designed circuit board, and only the motherboard functions related to the embedded application are retained, which can greatly reduce the system volume and power consumption.

Embedded microcontroller, also known as single chip microcomputer, as the name suggests, is to integrate the whole computer system into a chip. Embedded microcontrollers generally take a microprocessor core as the core

The DSP processor has a special design for the system structure and instructions, which makes it suitable for executing DSP algorithms, with high compilation efficiency and fast instruction execution speed. In digital filtering, FFT, spectrum analysis and other aspects, DSP algorithms are entering the embedded field in large numbers. DSP applications are transitioning from realizing DSP functions with ordinary instructions in single chip computers to using embedded DSP processors.

With the popularization of EDI, the popularity of VLSI design and the rapid development of semiconductor technology, many functional blocks can be combined to form a more complex system on one chip, which is SOC. It combines micro cores, such as arm RISC, MIPs RISC, DSP or other microprocessor cores, plus communication interface units, such as USB, tcp/ip communication unit, GPRS communication interface, GSM communication interface, Bluetooth module, etc.
