نویسنده
چکیده
In the FIR filter design the MCM block optimization plays a vital role to reduce the critical path which is due to the product accumulation section. The critical path delay is reduced by using the Transposed direct form (TDF) FIR filter is proposed. The filters which have large number of multipliers. The partial products by using OTFC-LRRS multiplier is implemented in the FIR filter. The array multiplier is differ from the Left to right carry free (LRCF) multiplier .By reducing the product accumulation the power delay and area delay performance of the proposed method is higher than other and the LRRS multiplier reduces the area ,power and lower .On the whole ,the power consumption and delay performance are reduced and the area, cost also reduced by the proposed method. In TDF FIR filter splitting concept is used, which means that the product accumulation section is divided and pipelining concept is used.
