IIR Digital Filter Design Based on DSP and SOPC

A design of IIR digital filter based on DSP and SOPC technology was respectively conducted in this paper. Then design principles and implementation schemes were put forward, and the schematics of the hardware circuits as well as the software flow chart were given in detail. The experimental results indicate that the SOPC design has the advantages of flexible controls, continuous output phase, high precision, high reliability, and that it has better application value compared with the method by using the DSP chip under the integrated development environment CCS (code composer studio).
