CORDIC implementation of digital heterodyne filter in VLSI

CORDIC (Coordinate Rotation Digital Computer) is an iterative digital algorithm, which allows rapid rotation of coordinates in the digital plane. The CORDIC can be used for the calculation of trigonometric functions. This iterative method of performing the transformations uses only shifts and adds. Significant savings in hardware can be achieved through the implementation of the heterodyne circuits of modulators, demodulators and filters using the CORDIC algorithm. In particular, significant hardware savings can be achieved in the implementation of a digital heterodyne filter in VLSI using the CORDIC algorithm.
