The Design Of Communication Interface Based On FPGA For The Multiprocessor System

Since the development of communication for signal processing applications, higher speeds and multiplicate I/O interface are required. Multiprocesser DSP system usually is a good method to implement real time signal processing. Due to FPGA suppurt more multiplicate I/O standards, an integrated FPGA and DSP system is a better schemes for the communication of signal processing system.This paper presents the design of a platform with four TigerSHARC201s and one EP2S60F1020 for WCDMA base-band signal processing. The basic background of linkport, PCI bus, SRAM interface and a detailed design of applicable FPGA are given. Experiment approved that the FPGA can implements 240MHZ linkport with TigerSHARC201, 66MHZ PCI BUS and 60MHZ sram interface, also shows good signal integrity and reliablity.
