The Implementation of High-speed Data Transmission Between Parallel Port and DSP in EPP Mode

One of the important applications of DSP is the high-speed data transmission between PC and DSP. The principle of high-speed data transmission between parallel port and DSP in EPP mode is analyzed in this paper. The hardware design frame and its parallel port program design are also discussed in detail. The method is testified to be feasible by debugging.[WT5HZ]
