The MAC unit is considered as one of the fundamental operations in DSP and it becomes a basic component in ApplicationSpecific-Integrated-Circuits (ASIC).The MAC unit determines the speed of the overall system; it always lies in the critical path. Developing a high speed MAC is crucial for real time DSP applications. In other words the MAC operation is the main computational kernel in Digital S...

The performance of most crypto systems is primarily determined by an efficient implementation of arithmetic operations. When implementing public key cryptography such as RSA the primary requirements are high speed arithmetic computation, small size and low power consumption and resistance to side channel attacks. In this paper an efficient way to explore fast modular operation has been explored...

Coordinate Rotation Digital Computer (CORDIC) algorithm is an established method in complex arithmetic function discovery using shift and add operations. An absolute Scaling-free CORDIC algorithm for cosine and sine function computation function has been implemented. A combination of third order approximation Taylor series and leading-one-bit detection algorithm has been adopted in this impleme...
