A CORDIC Architecture Implementation for Rectangular to Polar Conversion

Authors(2) :-Richa Sharma, Prof. Pooja Thakre

Co-ordinate Rotation DIgital Computer(CORDIC) is a simple and efficient algorithm for performing computing tasks such as the calculation of trigonometric, hyperbolic and logarithmic functions, real and complex multiplications, division, square-root and many more using simple add, subtract and shift operations. Rectangular to polar conversion is an important operation in ALU, DSP processors, wireless communication, multimedia etc. This conversion requires hardware implementation of squaring, square root and arctangent circuits, which results in hardware complexity, large area requirement and high power consumption. To overcome this drawback, rectangular to polar conversion is carried out using CORDIC architecture. This paper proposes pipelined CORDIC architecture for rectangular to polar conversion using much simpler, cheaper and efficient hardware. Pipelining increases throughput of the system. The implementation has been done in VHDL language and simulation can be done on XILINX ISE software.
