Real Time Fir And Iir Filter Design Using Matlab Interfaced With The Tms320 C31 Dsk
III Gomes Walter J., Rulph Chassaing · 2024
This paper describes the design and real-time implementation of FIR and IIR filters using MATLAB interfaced directly with the TMS320C31 (C31) digital signal processor.An FIR or IIR filter can be readily designed using MATLAB functions to generate a set of coefficients associated with a desired filter's characteristics.These coefficients are included in a generic filter program transparent to the user.While the filter's frequency response is plotted on the PC monitor screen, it is being implemented in real-time with the C31 on board a $99 DSP Starter Kit (DSK).The authors have developed the support files required to duplicate these results.These files are available to anyone interested.Similar techniques can be developed to interface MATLAB with a different type of digital signal processor.
