| Abstract: | A universal embedded speech processing platform based on TMS320VCS402 DSP is presented. Making use of smart coding circuit, maximal 48K extern DATA SRAM is expanded, and meanwhile independent parallel boot of the system is accomplished. Human - machine interface of keys and LCD display are also extended. Figure of system hardware structure, flow chart of main program and detail steps of realizing parallel boot are provided. |
