CORDIC algorithm is used for calculation of complex functions in signal processing and wireless communication applications.These functions are the combination of sine and cosine terms that are linked to complex analysis. Pipeline architectures are used in CORDIC al gorithm to reduce the critical path, increases the clock speed. An angle recoding method is used to reduce the latency and obtain the desired angle in least number of iteration. In this paper, Hardware efficient Digital sine and cosine wave generator is designed and implemented by using pipelined CORDIC architecture . Digital sine and cosine wave generator is modeled and verified usingXilinx 12.3 ISE. The results shows the significantreduction in critical path, increase in clock speed using pipelining and number of iterations is also reduced by Angle Recoding Method.
