在软件无线电系统中,DSP要处理的数据量较大,处理的实时性要求比较高,目前采用DSP并行处理是提高DSP数据处理能力最切实可行的方法之一。文章详细分析了DSP多通道缓冲串行口McBSP多通道工作方式的特点,提出了一种新的基于McBSP的DSP多机通信设计方案,很大程度上提高了DSP在软件无线电系统中的数据处理能力。
In the software radio system, DSP to deal with a large amount of data, real-time processing requirements are relatively high, the current DSP parallel processing is to improve DSP data processing power is one of the most practical and feasible method. This paper analyzes the characteristics of DSP multi-channel buffered serial port McBSP multi-channel working mode in detail, and proposes a new design scheme of DSP multi-machine communication based on McBSP, which greatly improves the data processing of DSP in software radio system ability.
