ACKNOWLEDGEMENT
I am extremely grateful to my guide Prof. K.K. Mahapatra for giving me the opportunity to work under him and for giving the topic to work on, which was both extremely interesting as well as challenging. His timely advice from time to time, however, made life much easier than it would have been.I am also grateful to Mr. Jagannath, Mr Anup Sarma and Mr Soubhagya Sutar without whose help, CoWare would have always remained an unsurmountable task. It was because of their help and tips that I was able to complete my thesis on time.

Last but not the least, I am thankful to my family, all my professors and friends without whose support this work would never have been possible.

ABSTRACT
Efficient generation of trigonometric as well as exponential functions without much increase in hardware complexity has always been a challenge, owing mainly to their importance and widespread use in Digital Signal Processing applications besides other areas.One such algorithm which is very much effective for the calculation of trigonometric, hyperbolic, exponential, linear and logarithmic functions is the CORDIC algorithm. The algorithm is very much hardware efficient because it omits the dependence on multipliers and is rather a combination of shift-add operations.

Application Specific Instruction-set Processors (ASIPs) are a type of processorthat serve as a compromise between General Purpose Processors (GPPs) and Single Purpose Processors (SPP). Their data-path can be optimized for a particular class of operations such as embedded control, Digital Signal Processing (DSP) applications etc. This project deals with the design of an ASIP based on the CORDIC algorithm using two very popular hardware designing tools, i.e , Xilinx IntegratedDevelopment Environment (IDE) from Xilinx corporations, Inc. and LISA 2.0 description language and processor designing environment from CoWare.
