Abstract: In the modern communication, sonar and radar systems, it needs to process huge data. One of the effective ways to solve this problem is to build a system with multiprocessor, so it can enhance the processing ability. According to the demands of the system, this paper designs a high speed array signal processing board which is based on CPCI structure. It chooses the TigerSharc101 as the core processor, the peak processing ability of the board is 14.4GFLOPS. The board has link ports to realize the communication between TS101 and boards. This paper introduces the base structure of the board and FPGA design and emphasizes on the host interface design. These applications show that the board has a great processing ability and expansibility.
