چکیده
An exact Filter Design Optimization (FDO) algorithm that can guarantee the minimum design complexity, but can only be applied to filters with a small number of coefficients. Then introduce multiple constant multiplications and using exact and approximate algorithm that can handle filters with a large number of coefficients using less computational resources than the exact FDO algorithm and find better solutions than existing FDO heuristics. These algorithms can be modified to handle a delay constraint in the shift-adds designs of the multiplier blocks and to target different filter constraints and filter forms. Experimental results show the effectiveness of the proposed algorithms with respect to prominent FDO algorithms. In this FDO technique there are three type of FIR technique we use to implement the graph based, common sub-expression elimination, digit based recording algorithms and compare the area and delay

An Efficient LUT Design on FPGA for Memory-Based Multiplication
An efficient Lookup Table (LUT) design for memory-based multiplier is proposed. This multiplier can be preferred in DSP computation where one of the inputs, which is filter coefficient to the multiplier, is fixed. In this design, all possible product terms of input multiplicand with the fixed coefficient are stored directly in memory. In contrast to an earlier proposition Odd Multiple Storage ...
