Abstract :
In this paper, an efficient implementation algorithm of IIR filter is proposed based on complex programmable logic device (CPLD). As an example, an IIR notch filter is designed with very high speed integrated circuit hardware description language (VHDL) and real time implemented on ALTRA Corporation´s ACEX 1K series CPLD chip. The implemented IIR notch filter is tested and the result of the example from the proposed hardware implementation is also presented to show the effectiveness of the algorithm
