Abstract :
Based on FPGA, a digit-serial FIR filter is implemented. According to the digit-serial algorithm, the digit-serial FIR filter is composed of foundational function modules including the digit-serial adder, the digit-serial multiplier and the delay circuit. Compared with the traditional method, the digit-serial FIR filter based on FPGA exhibits the advantages of high response speed and low hardware consumption. Furthermore, the relationship between the speed and the area is adjusted in a better manner in the digit-serial FIR filter The digit-serial FIR filter with N=2 has the minimum of area-time product
