【Abstract】 Discrete trigonometric function generator has great applications in DSP. The principles of CORDIC is introduced in this paper first. Then a new pipelined architecture to realize discrete trigonometric function generator in high speed and accuracy is described. After that is the design process with VHDL. In the end, the hardware simulation result with Xilinx’ FPGA is given.\;更多还原
