It completes the auto generation of DSP code withof Real-Time Workshop. It realizes the moduler programming in MATLAB environment. The experimentshows that the automatically generated program runs smoothly in TMS320F2812 development board and the result iscorrect. It proves this method can improve efficiency of dsp development and it has a certain practical valueKey Words DSp2812 MATLAB modular programming code auto generation SPWM modulationC1994-2013ChinaAcadcmicJournalElcctronicPublishingHousc.Allrightsrescrved.http://www.cnki.nct
