| 摘 要： | 首先简要介绍了共享总线式系统和分布式系统两种多DSP并行信号处理系统的特点,之后提出了一种共享总线式系统的设计方案,该系统通过多DSP互联并共享大容量存储器达到了高速实时信号处理所需要的运算和吞吐能力要求,同时通过总线令牌设计有效的解决了各DSP在访问共享存储器时产生的总线竞争问题。

| Abstract: | This paper firstly introduces the features of the two kinds of multi - DSP parallel signal processing system, the bus- shared system and the distributed system. Then it proposes a practical design of the bus - shared system, which fulfills the requirements of the high - speed and real - time signal processing on the com- puting and data throughput by means of inter - connecting DSPs with large memory shared. The problem of bus contention which occurs when DSPs access the shard memory is also solved by bus token in this system. |
