A real-time processing system on array signal is designed in this paper. Multiplex high-speed fiber is used to transmit data. Four processors form an interconnected topology structure, and data can be transmitted between any two processors, which can process data simultaneously. Large capacity memory is equipped for every processor to meet storage of mass data. It uses two FPGA device to control system timing and interface. According to the task assigned to each processor , algorithm running time and data transmit time is estimated. The system is being used in a project and running stably, which indicates that the design is feasible.
