Zusammenfassung:The performance of finite impulse response (FIR) filtering is an important index of the real-time processing ability of digital signal processing system. In this paper, various FIR filtering algorithms are analyzed, and based on fast fir algorithm (FFA), block FFA (BFFA) is proposed. A 128 order configurable FIR filter circuit with 16 order as a block is designed. The analysis of experimental data shows that the 16 bit integer FIR filter performance reaches 881.78Gop/s.
