G.723.1 Dual Rate Speech Coder: Multichannel TMS320C62x Implementation (Rev. B)

This application report describes how the G.723.1 Dual-Rate Speech Coder has been implemented on the TMS320C62x digital signal processor (DSP). Beyond the use of the ?C62x intrinsic functions, the application report includes specific changes required to allow this coder to operate in a real-time system with other speech coders. Also reported is information on several optimization techniques used to yield multiple channels running concurrently. Finally, the application report will include the performance resulting from this implementation of the algorithm. Source Code examples discussed in this application report are available under license. Please contact your local TI Sales Representative for more information.
