Novel Structure for Area-Efficient Implementation of FIR Filters.
IEEE Transactions on Circuits and Systems II: Express Briefs(2017)
Abstract
It is observed that in multiplierless implementation of transposed direct form finite impulse response (FIR) filters, the adders in the product-accumulation block, which are called structural adders (SAs), contribute the major part of the overall logic complexity. A novel FIR filter structure is therefore proposed to reduce the hardware complexity of the product-accumulation block. In the proposed...
