The efficient memory computing system alternative to conventional logic computing is required in DSP applications. The LUT-designed using combined APC-OMS technique can be used for these applications. APC-OMS technique reduces the LUT size to one-fourth of its original. In this paper, FIR filter is designed using conventional LUT. If conventional LUT is used, the on-chip memory size is getting larger. The memory size can be reduced by decomposing the LUT. FIR filter is designed using multiplexer which is used to select the filter co-efficient. With LUT, area and delay efficiency cannot be achieved. This design has less number of memory accesses and area than LUT based FIR design. By the proposed method, 50% area efficiency and 20%throughput is achieved.
