Design of Floating-point Vector Coprocessor Based on FPGA
HE Shu-zhuan · Jisuanji gongcheng · 2012
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.
