摘要
文中构建了以 TMS320DM642为核心的硬件图像跟踪处理系统,但 TMS320DM642的 CPU 片内内存较小,原来的两步 SSDA 图象跟踪算法无法快速运行,这样文中对两步 SSDA 图象跟踪算法作了改进,使之在保持原来的跟踪精度、可靠性、抗干扰能力的同时可以高速运行在小内存的 DSP 系统上。
In this paper we have designed a hardware image tracing processing system based on TMS320DM642.However internal storage of the CPU chip for TMS320DM642 is very limited and a two-step SSDA image tracing algorithm can- not be run quickly.So we have improved the algorithm and made it remain its original tracing preciseness,reliability and antijamming ability.In the meantime it can be used for a DSP system with limited internal storage in high speed.
