Abstract

when the software implements the design of infinite impulse response filter (IIR filter), the larger the amount of filtering data and the higher the filtering order, the more time will be spent because of the data shift of each calculation.^[1] By means of parameter replication, the IIR filtering software replicates the parameters once when initializing the software. In the calculation of IIR filtering, the array subscript changes in a cycle ^[2], replacing the way of data shift for filtering calculation, thus greatly improving the execution efficiency of the software and saving the operation time. The higher the order of IIR filter, the higher the efficiency of software promotion and the more time saving.
