In DSP the most common function is Finite Impulse Response (FIR) filter which is realized in field Programmable gate Arrays (FPGAs). For efficient Very Large Scale Integration (VLSI) computation systolic FIR filter architecture has attractive models. High speed is the major concern for fast computation in real time Digital Signal Processing (DSP) applications. In conventional systolic FIR filter method uses general array multiplier structure which takes more time to compute the process with high design complexity with less power. To overcome this problem the systolic FIR filter utilizing Bypass Feed Direct Multiplier(BFDM) is proposed. The proposed method 16 tap systolic FIR parallel processing offers less delay with less design complexity which is used in image and signal processing applications. The proposed method is simulated using Xilinx ISE 12.4 ISE tool and the functions are evaluated by MODELSIM 6.3C.
