The method of implementing video image compression coding through DSP features good flexibility and extensibility, and it can overcome some constraints of special chip video coder and FPGA video coder and has wide application prospect. This paper introduces the video coder hardware platform based on DSP64XX, analyzes in detail the integrality of high-speed digital signal of external memory of coder, and implements the simulation of signal transmission waveform of data line and address line. The software framework and software optimization strategy of DSP video coder are expounded. This coder has been widely used in engineering and its performance is stable and reliable.
