| Abstract: | This paper discusses the design of 2-dimensional code reader based on TMS320DM642 which is designed for video development by Texas Instruments Corp. In the hardware design, TVP5102 and SAA7104 chips are used for sample and loopback the input image. The circuit design of DM642 module, video input interface and output interface is emphasized in hardware design section. The software design section includes video sample driver based on DSP/BIOS, program flow, and vision arithmetic. DSP/ BIOS configuration tools, CSL and FVID of CCS and TI are emphasized. |
