基于“魂芯一号”的雷达信号处理机设计

摘要

A new general radar signal processor is designed, which is based on four pieces of "HunXin-1" high performance DSP processor and one piece of FPGA. In the processing system, the point to point communications of the four DSP chips are implemented by the high speed link ports, the data pretreatment and the protocol transfer of interface are implemented by high level FPGA made by Altera Inc. The processor has good capabilities of computation and data exchange, excellent universality, reconfigurable performance and expansibility. Finally the performance and application value are confirmed through computing performance measurement and the signal processing of a digital array radar(DAR), which employs the "HunXin-1" chips in its signal processor.%以4片“魂芯一号”国产高性能DSP处理器和FPGA为核心,设计了一种新型通用雷达信号处理机.处理机采用高速链路口实现4片DSP处理器之间的点对点通信,采用Altera公司的高端FPGA芯片作数据预处理和接口协议转换.该处理机具有很高的运算性能和数据交换能力,并具有较好的通用性、可重构性和扩展性.通过运算性能测试,并在信号处理机上实现某数字阵列雷达信号处理,验证了“魂芯一号”的性能和应用价值.
