实时阵列信号处理系统设计

Real-time processing system design on array signal

根据实际项目需求设计了一种实时阵列信号处理系统,采用多路高速光纤作为数据输入、输出接口;4片处理器组成互联的拓扑结构,任何两片处理器之间都可以互相传送数据,多片处理器可同时对数据进行高速处理;系统配备了大容量存储器,可满足大量数据的存储要求;采用两片现场可编程门阵列器件对系统接口、时序进行控制;为每片处理器分配了处理任务,并对信号处理算法运行时间及数据传输时间进行评估。该系统已在实际项目中运行,充分满足项目要求,运行稳定,验证了本系统设计的可行性。

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.
