<p>Many hardware efficient algorithms exists for hardware signal processing architecture. Among these algorithm is a set of shift-add algorithms collectively known as CORDIC (COrdinate Rotation for Digital Computers) for computing a wide range of functions including certain trigonometric, hyperbolic, linear and logarithmic functions. The paper compares the different CORDIC architectures with respect to their area, speed, and data throughput performance especially in three different major styles iterative, parallel and pipelined structures. All three designs were designed in VHDL, simulated using Modelsim simulator and Implemented using Xilinx FPGA synthesis and Synopsis ASIC synthesis tools. ©2010 IEEE.</p>
