Using DMA memcpy on DSP

Neel Badadare

Hello,

I am using vision sdk 2.10 (linux) on TDA 2x. I want to use memcpy on DSP using DMA/EDMA.

Please let me know complete procedure (files to be included and memcpy functions) for using DMA/EDMA memcpy.

Hi Neel,

Please refer to ~/vision_sdk/examples/tda2xx/src/alg_plugins/framecopy/frameCopyAlgoLocalDma.c for the example code to utilize EDMA for memory copy.

You can also find the Utils_dmaXXX APIs descriptions in API Guide.

Regards,

Stanley
