| Abstract: | An image sampling and recognition system based on TMS320VC5509A DSP is designed and implemented. In this system, the image sampling unit and processing unit are composed of a CMOS sensor and a DSP, respectively. All logic functions are controlled by CPLD. The parallel booting problem, which occurs when the number of the address lines provided by DSP is less than that of the asynchronous memory, is also solved. Experiment results show the stability, real-time feasibility and programmable flexibility of this system. |
