IMPLEMENTING A REAL-TIME SYSTEM FOR LUNG SOUND SPECTROGRAPHS USING THE TMS320C30

This application report describes how to develop a real-time system for producing lung sound spectrographs and other analyses using the Texas Instruments (TI™) TMS320C30 (C30) digital signal processor (DSP). The C30 floating point processor, hosted by a PC with a 486 DX2 processor (or better) is written entirely in the C language. With this real time system, analog input can be captured directly from a microphone and processed on the C30. The results can be sent to the PC and displayed graphically with negligible delay.
