提高Blackfin系列DSP中代码的并行性

Improvements on DSP Code Parallelism of Blackfin Series

为提高Blackfin系列DSP代码的并行性,分析了它的硬件结构和指令系统的特点,讨论了DSP平台上优化设计的一般性规则,提出了几种提高代码并行性的优化方案,同时对优化实例进行了测试比较,优化效率可达到5倍以上.

To improve the parallelism of Blackfin code, the attributes of its hardware architecture and instruction system were analyzed. Moreover, the generic rules for DSP platform were also discussed. Meanwhile, some optimization measures were given to increase code parallelism, and the optimization instances were tested and compared. The efficiency of optimization can be up to as many as 5 times.
