CORDIC or CO-ordinate Rotation Digital Computer is a fast, simple, efficient and powerful algorithm for diverse Digital Signal Processing applications. Primarily developed for real-time airborne computations, it uses a unique computing technique which is especially suitable for solving the trigonometric relationships involved in plane co ordinate rotation and conversion from rectangular to polar form. It comprises a special serial arithmetic unit having three shift registers, three adders/subtractors, Look-Up table and special interconnections. In this project A CORDIC processor for sine/cosine calculation was designed using VHDL programming in Xilinx ISE 13.2. The CORDIC module was tested for its functionality correctness by test-bench analysis. Subsequently, FPGA implementation of the CORDIC core followed by Chip Scope Pro analysis of the waveforms was performed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
