Title: Coordinate Rotation DIgital Computer (CORDIC) synthesis for FPGA
Abstract: An universal CORDIC processors is able to compute a wide variety of functions, for example conversion between polar and cartesian coordinates, trigonometric (sin,cos,tan and vice versa), division, hyberbolic and exponential functions. Because CORDIC needs only simple add/subtract and shift operations, it is easy to realize it with FPGAs. We explain the CORDIC synthesis in different architecturs and of different accuracies. We examine the CORDIC synthesis for coordinate conversion from cartesian to polar X, Y → R, θ and for computing the exponential function with the CORDIC processor supporting a former implemented artifical neural network. With our optimization the hardware effort of the CORDIC could be reduced, so that each processors may be implement each with one XC3090 FPGA from Xilinx.
