FIR filters are used in many performance/power critical applications such as mobile communication devices, analogue to digital converters and digital signal processing applications. Design of appropriate FIR filters usually causes the order of filter to be increased. Synthesis and tape-out of high-order FIR filters with reasonable delay, area and power has become an important challenge for hardware designers. In many cases the complexity of high-order filters causes the constraints of the total design could not be satisfied. In this paper, efficient hardware architecture is proposed for Distributed Arithmetic (DA) based FIR filters. The architecture is based on optimized combination of Look-Up Tables (LUTs) and compressors.
