Design of Multi-channel Speech Coding Platform Based on TMS320C64xx
Xiaoyun Wang · Modern Electronics Technique · 2008
This article describes a TMS320C64xx based multi-channel speech coding software platform design.The platform meets the application requirement that any kind of speech coding algorithm could be performed without changing software structure.Based on progressive frame processing design concept,data processing flow on both HPI and McBsp interfaces are optimized.EDMA controller is used to control external data transmitting and receiving.This approach does not require DSP kernel resources.The platform shows high coding efficiency and good extensibility.
