摘要
This paper introduces a system based on Tls fifth generation DSP(Digital Signal Processor) device-TMS320C50 to construct the simplest system of digitalizing underwater video signal. The system realizes collecting 3 different density image data by means of software designation. The system may expand its outer data memory to 4 Giga byte by using a technology of memory page extension. Two different interface circuits for different speed peripheral devices and C50 are also designed: one is high speed A/D, and the other is static memory whose access time is 70ns. The system can digitalize analog video signal and process the gathered data in limited time.
