Abstract

The invention relates to a general digital image processing system comprising a digital processing module, a storage module, a VGA (Video Graphics Array) module, a PAL (Programmable Array Logic) module, a general input-output interface module and a general asynchronous serial transceiver, wherein the digital processing module is used for compiling and processing programs according to specific application and realizing core calculation and processing; the storage module is used for storing images and parameter data; the VGA module is used for converting a digital signal output by the digital processing module into a VGA signal and outputting the VGA signal; the PAL module is used for converting the digital signal output by the digital processing module into a PAL signal and outputting the PAL signal; the general input-output interface module provides an user-defined I / O (Input / Output) interface connected with the digital processing module for users; and the general asynchronous serial transceiver realizes conversion between an RS422 difference electrical level and a single-end electrical level so as to realize full duplex communication with an upper computer. The invention providesa small general digital image processing system which has small circuit occupying space and complete function, and can be applied under various situations.

Description

technical field

[0001] The invention relates to a digital image processing system, in particular to a general image processing system for digital video, belonging to the field of image processing. Background technique

[0002] Today's image processing basically adopts digital processing technology. However, in the prior art, dedicated digital image processing circuits are designed for specific applications. This practice of designing different dedicated circuits for different systems will greatly increase the time, risk and cost of project development. In digital image processing circuits, although different systems have different requirements, there are actually some common requirements and designs among different dedicated systems. If these common requirements and designs can be analyzed and extracted, a miniaturized, versatile and functional digital processing core system can be designed, which can meet specific project requirements with only a small number of periphera...
