摘 要：Since the ⅡR design is very difficult and time-consuming by using the hardware description language directly, this paper presents a simpler and more efficient method for IIR digital filter design. This design is based on Batterworth analog filter, using the impulse response invariant method. The design steps are: design non-quantitative ⅡR filter using Matlab;convert the designed ⅡR filter of M language into hardware description language using AccelDSP;then verify and synthesize the ⅡR design using ISE 10.1 of Xilinx. The design is verified by timing simulation and can be implemented on FPGA directly. The key of this design is to analyze the ⅡR digital filter algorithm, then describe it through the synthesizable m language and finally convert the m program to RTL design by using AccelDSP. The aim of this paper is to simplify the ⅡR digital filter design.
