摘要
在基于VME总线或CPCI总线的雷达信号处理机中,板与板之间的数据传输速率受限于总线的速率。针对现有的雷达信号处理机板间的数据传输速率较低的问题,本文提出了一种新的设计方法,即采用DSP和FPGA相结合的设计方法,利用FPGA提供的高速串行收发通道进行板间的数据传输,使板间的数据传输速率获得大幅度的提升,同时也有效地改善了板内DSP间的数据传输问题。
The data transfer rate between varied boards in radar signal processors based on VME or CPCI bus was limited by the bus rate. To solve the problem of the low data transfer rate between varied boards in radar signal processors,this paper proposes a new design method, combining the DSP with FPGA and using the highspeed serial channels built in the FPGA to transfer data between varied boards. Then the data transfer rate between varied boards is improved greatly. Meanwhile,the problem of the data transfer between DSPs in the same board is also solved effectively.
