Design of Hardware Platform of Speech Processing System Based on TMS320C5509 DSP

The digital signal processing(DSP) is the key technology of the speech signal processing. This paper studies the speech processing system with the digital signal processing technology, and designs a speech processing system based on DSP. The system uses TMS320C5509(a DSP chip of the TI Company) as the processing core to collect, convert and filter the signals in digital form, and finally builds a hardware platform according to the required versatile speech signal processing.
