Abstract: 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.
