High Speed Convolution and Deconvolution Using Urdhva Triyagbhyam

Convolution and Deconvolution has many applications in digital signal processing. Multipliers and dividers are basic blocks in convolution and deconvolution implementation. They consumes much of time. With advances in technology, many researchers have tried and are trying to design multipliers and dividers which offer either of the following-high speed, low power consumption, regularity of layout and hence less area or even combination of them in multiplier and divider. In this paper, direct method is used to find convolution and deconvolution. Discrete linear convolution of two finite length sequences using Urdhva Triyagbhyam algorithm is presented here. Same algorithm is also used for deconvolution to improve speed. This design approach efficiently and accurately speeds up computation without compromising with area.
