Abstract: This paper presents the realization of a great-storage-capacity high-speed parallel digital signal processing board based on ADSP-TS101S processors. The board has a loose coupling architecture as well as compact interface and great storage capacity and can communicate with PC through ISA bus. The timing on the board can be controlled by CPLD. It is so very flexible that it can be used in many applications which need high-speed DSP processing to implement the task of high-speed real-time signal processing.
