Hi Betty,

You can find a detailed description of EDMA3 in the C6745 TRM: www.ti.com/.../spruh91d.pdf

Processor SDK RTOS for OMAP L137 also includes EDMA component and LLD drivers for C6745 DSP that you can use for reference. www.ti.com/.../processor-sdk-omapl137

You can also find more information in the RTOS Software Developer Guide found here: processors.wiki.ti.com/.../Processor_SDK_RTOS_EDMA3

Hope this helps, please let us know if you have any questions.

Best,
Sahin
