A programmable voice digitizer using the T.I. TMS-320 microcomputer
D. Daly, L. Bergeron · 2005
With the availability of single-chip high speed digital signal processors, it is now possible to perform computationally complex voice digitization and compression within single board constraints. A new u-processor based system has been designed, within this constraint, around the TMS-320 signal processor. The hardware blocks needed to accomplish these requirements consists of a high speed microprocessor with fast multiply/accumulate, a data management section, an analog I/O section and a host DMA interface.
