一种高效的DSP与FPGA的数据交换结构设计

摘要

In the conventional DSP and FPGA architecture systems, when making data exchange, because the DSP resources are occupied too much for data processing and preparation, the software execution time is increasing, resulting in the decline of execution efficiency of the whole system.To improve the execution efficiency of the DSP and FPGA architecture system, we design a efficient data exchange architecture of DSP and FPGA, which combines the characteristics of parallel process combining with FPGA, FPGA make classifying decoding, conversion process for external data, thereby improving execution efficiency of the DSP.%常规DSP与FPGA构架系统中,在进行数据交换时,由于DSP资源过多的被占用来进行数据处理和准备,增加软件执行时间,从而导致系统整体的执行效率下降.为了提高DSP结合FPGA构架系统的执行效率,本文设计了一种高效的DSP与FPGA数据交换结构,该结构结合‘FPGA并行处理的特点,FPGA内部完成对外部数据进行分类,解码、转换处理,从而提高了DSP的执行效率.
