Image processing system based on FPGA

Abstract

The invention discloses an image processing system based on FPGA, comprising an image processing chip FPGA module; the FPGA includes an ARM interface module, an SDRAM control module, a command interpretation module, a display control module and a bus arbitration module, wherein the ARM interface module of the FPGA is also connected with a main controller which is an ARM microprocessor. The image processing system not only utilizes the ARM microprocessor so as to have the characteristics of having rich command sets and flexible programming, but also develops the advantages of the FPGA in the aspects of speed and parallel arithmetic, thus having and developing the advantages of the ARM microprocessor and the FPGA, and improving the efficiency, the flexibility and the upgradability of the system.

Description

technical field [0001] The invention relates to an image processing system, in particular to an image processing system based on an FPGA chip as an image processor. Background technique [0002] There are currently several image processing hardware implementation methods: (1) dedicated standard circuit (2) application specific integrated circuit (3) digital signal processor (4) field programmable gate array. [0003] (1) Application Specific Standard Circuit (ASSP) [0004] Application-specific standard circuit (ASSP) is a common standard device. When image processing algorithms and standards are changed or new algorithms and standards are proposed, ASSP is difficult to upgrade and quickly adapt to the development of technology. At the same time, ASSP does not allow product customization, which makes developers need additional hardware to customize their own products to reflect product differences, increasing costs and reducing performance. In addition, developers cannot o...

However, due to the specificity of ASIC, it has the following disadvantages: long development cycle

[0011] It can be seen that the current image processing system can choose ASSP, ASIC or DSP, but these three methods have their own shortcomings: ASSP lacks flexibility and is difficult to upgrade; ASIC has a long development cycle and high cost; DSP is difficult to meet specific needs
