摘要 为满足现代数字信号处理中大量数据的运算需求,利用ARM946和Xilinx公司的现场可编程门阵列芯片逻辑资源和IP库,设计专门用于浮点复数向量运算的64位协处理器,对相关浮点运算进行优化,并在硬件仿真平台上进行测试。结果表明,该协处理器可使浮点复数向量运算性能得到大幅提高。 To meet the requirement of a series of complex data processing in modern Digital Signal Processor(DSP),a 64 bit floating-point coprocessor specially for floating-point complex vector arithmetic is proposed with the logic resources and IP library of ARM9 and the Field Programmable Gate Array(FPGA) chip from Xilinx.The algorithm of related floating-point arithmetic could be revised.Results of the test on the hardware simulation platform show that the floating-point complex vector arithmetic performance is greatly improved by the coprocessor.
