Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] figure 1 It is a topological structure diagram of a general digital image processing system realized according to the present invention. The digital processing module is the core device of the system, and it should choose a digital processing device with strong functionality, strong versatility, and easy to change design. A high-performance FPGA(1) is the device of choice to meet this condition.

[0022] Such as figure 1 As shown, the whole system uses FPGA(1) as the core processing device, and the periphery includes 4 pieces of synchronous SRAM(2), a piece of NAND flash(7), a piece of SDRAM(6), a piece of VGA DA(3), and a piece of PALDA(4) , two RS422 differential level conversion chips (5), two 60-pin digital interfaces (8) each. All devices are integrated on one circuit board. The circuit board can be designed so that the components are reasonably distrib...

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...
