FIR Filter Technology has evolved as an eminent technology which has revolutionized the world of Digital Signal Processing (DSP).In addition, the characteristics of a digital filter can be easily changed under software control making them versatile.The research done in this paper focuses on the drawbacks of the given conventional structures and proposes a method to improvise them.The method given in this paper combines the architecture of linear and concurrent structure to achieve a semi concurrent filter with half the number of multipliers conventionally required.To authenticate this research, simulation of this FIR Filter was done and compared with traditional linear and concurrent structures in terms of sampling rates and chip area utilization.
