Abstract: A new technique of design and implemention of embedded general image enhancement chip is introduced in the paper.The chip helps microprocessor finish displaying task and lightens the work burden of microprocessor，it not only increases the speed of image processing but also improves the system’s response and real-time.This image enhancement chip has general control bus，data bus and address bus，it can communicate with different embedded microprocessor，and can be direct accessed by the microprocessor as parts of microprocessor’addressing space.The system of the chip is analyzed，and the function of each module is discussed in detail.It is verified on FPGA，the result is proved that the design achieves the goals expected.

Key words: embedded microprocessor, image enhancement chip, Field Programmable Gate Array（FPGA）
