DESIGN OF FIR FILTER USING LOOK UP TABLE AND MEMORY BASED APPROACH

The main objective of this Paper is to develop Finite Impulse Response (FIR) Filter using look-up table (LUT) and memory based processor. The configuration is to reduce memory size, logic gate count and improve the speed of operation. Digital filters are becoming ubiquitous in audio applications. As a result, good digital filter performance is important to audio system design. Digital filters differ from conventional analog filters by their use of finite precision to represent signals and coefficients and finite precision arithmetic to compute the filter response. In this Paper, FIR filter is implemented in Xilinx ise using VHDL language. VHDL coding for the FIR filter is implemented in this Paper and waveforms are observed through simulation.
