ABSTRACT
Evaluating trigonometric functions, used in Digital Signal Processing applications like Discrete Fourier Transform (DFT), Discrete Hartley Transform (DHT) is a complicated task involving large area, high complexity and time issues. To reduce the delay at the expense of area constraints an optimized hardware efficient technique called Coordinate Rotation Digital Computer (CORDIC) is used. CORDIC technique is implemented, without use of multiplier, which eases the process. This journal presents how CORDIC technique is implemented in pipelined mode for different applications such as computing trigonometric functions to determine FFT, data conversion.
