CORDIC Algorithm Implementation in FPGA for Computation of Sine & Cosine Signals

Many hardware algorithms exist to handle the hardware intensive signal processing problems. Among these algorithms is a set of shift-add algorithms collectively known as CORDIC for computing a wide range of functions including certain trigonometric, hyperbolic, linear and logarithmic functions. While there are numerous articles covering various aspects of CORDIC algorithms, very few survey more than one or two, and even fewer concentrate on implementation in FPGAs. The work presented here associated with FPGA implementation of CORDIC systems for fast and silicon area efficient computation of the sine and cosine functions. The results of theoretical investigation into redundant CORDIC have been presented here. Summary of CORDIC synthesis results based on Actel and XILINX FPGAs is given. Finally applications of CORDIC sine and cosine generators in small satellites are discussed.
