An Efficient Realization of FIR Filter Architecture for Higher Lengths

Sheena Pathan | Rahamtula Shaik

Abstract: A Finite Impulse Response (FIR) Filter whose impulse response is for a finite duration can be implemented in two forms Direct form and Transpose Form. The direct form realization supports block processing whereas the transpose form doesnt. The transpose form structure is more efficient when we it comes to the realization of medium or higher order filters whereas direct form suits best for realizing only short length filters. The transpose form realization of FIR filters supports MCM (Multiple Constant Multiplications) scheme and this will lead to ease in computational analysis. In this paper, we analyze the block formulation of FIR filter in transpose form by using MCM based approach. It also includes detailed research on the impact of the MCM block in the structure. The proposed realization of FIR filter architecture results in reduction on delay and also facilitates area savings. The modified structure also speeds up the output generation process being less complex and enhances in saving the number of computations.
