Hardware design of image recognition system based ARM and FPGA

Hardware design of image recognition system based on ARM and FPGA is introduced. System is compartmentalize into three modules, image collection and low-level processing module, which include the CMOS image sensor control, video data collection; video data preservation and VGA display module; System management and external interface modules, which include USB, Ethernet, PS2, and RS-232 etc. The FPGA internal functional module is introduced in detail, which include initialization control of image collection, data flow generation control of camera pixel, video data processing, SDRAM control, VGA control, sequential control of modules working ,etc.
