High speed multiplier for FIR filter design using window

The high speed multiplication operation plays vital part in Digital Signal Processor (DSPs) as well as in general processor. Finite Impulse Response (FIR) filter with higher speed is of great importance. FIR filter is also called convolution filter since convolution is the fundamental concept of designing FIR filter. Vedic Mathematics is based on 16 sutras. One of the sutra is Urdhava Tiryagbhyam which delivers a difference in the actual process of multiplication itself. In this paper, we proposed a high speed multiplication operation based on Urdhava Tiryagbhyam sutra to design FIR filter using window. This algorithm is implemented in MATLAB and performed in GUI. Further the execution time taken by FIR filter processor is compared by Urdhava of Vedic method and inbuilt MATLAB function. In the results, it can be seen that FIR filter based on Urdhava Tiryagbhyam sutra reduces the execution time as compared to inbuilt function of MATLAB.
