FPGA Design, Implementation and Analysis of Trigonometric Generators using Radix 4 CORDIC Algorithm

Today, many of the computations in signal processing and wireless communication applications are linked with complex analysis of several functions. These complex functions are combination of sine and cosine terms that generally spread in the channel. Most of these functions can be split into elementary functions. Today user’s desire every gadget must be smaller in size and simple to operate (“Keep it small and simple”). So the researchers muddle through speed area tradeoff. The CORDIC algorithm is one such kind of algorithm. In this paper hardware efficient trigonometric generator is designed and implemented on Spartan 3 FPGA. The results obtained are compared with that obtained using MATLAB.
