Area and Energy-efficient Approximate Distributive Arithmetic architecture for LMS Adaptive FIR Filter

A novel approximate DA architecture is proposed for adaptive FIR filter. LMS algorithm is used to update the weights of the filter. In this architecture we combined the CSD number and DA technique to improve the area and power efficiency of the filter. LUT-less DA computation is done. Instead regist...
