Filter enables real-time performance

The purpose of designing a programmable linear phase finite impulse response (FIR) filter is to create an integrated circuit (IC) to perform in real time, various digital audio and signal filtering applications. The pipelined architecture of the filter is designed to maximize throughput and allow the user to reload coefficients to change filter characteristics without interruption while processing. Using a 0.5-mu technology, the Design is predicted to execute a 64- tap filter function with 16-b signal data at a sample rate of at 1 MHz
