高性能计算中应用驱动的多DSP处理器阵列研究

摘要

数字信号处理(DSP)芯片是一种特别适合于进行数字信号处理运算的微处理器,高性能计算由于大数字运算量和高速处理的要求,非常适合于DSP的应用.针对工业CT图像的三维重建这一典型应用,分析了DSP在高性能计算中的应用特点、方式和效果,提出了一种动态可重构的多DSP处理器阵列的设计方法.最后通过软硬件仿真验证了DSP在高性能计算中的性能和多DSP设计方案的可行性.%DSP is a suitable kind of micro-processor for digital signal processing.High-performance computing,which requires large-scale computation and high-speed processing,is a typical application for DSP.This paper analyzed a typical high-performance computing , generalized the characteristics, means and effect of DSP in this typical high-performance computing.Then put forth a method of designing reconfigurable mutil-DSP array.
