CORDIC is an acronym for Coordinate Rotation Digital Computer. It is a class of shift and adds algorithms for rotating vectors in a plane, which is usually used for the calculation of trigonometric functions, multiplication, division and conversion between binary and mixed radix number systems of DSP applications, such as Fourier Transform. A fast and energy-efficient CORDIC for the calculation of elementary function is always needed in electronics systems i.e. DSP processors, image processing and arithmetic units in microprocessors. On VLSI implementation level, the area also becomes quite important as more area means more system cost. The three parameters i.e. power, speed and area are always traded off. For DSP processors area and speed are the main ones. But sometimes, increasing the speed also increases the power consumption, so there is an upper bound of speed for a given power budget. Since elementary functions calculation dominates the execution time of most DSP algorithms, so there is need for high speed CORDIC algorithm. In this thesis, a very high speed CORDIC algorithm is implemented for fast calculations and generation of trigonometric functions for generation of waveform VHDL is used to implement a technology-independent design.
