I want to understand PDMA concept. Please let me know if there is any document for the same

  • Hi Srinivas,
    We would suggest you refer the section "Peripheral Control Commands " in pg. 1306 of ADSP-21569 HRM which is given below where you can get information about PDMA.
  • Hi Ranjitha,

         Thanks for quick response, May be my question was not clear. I actually want to understand the theory behind DMA like below mentioned points.

        1. The basics of DMA control
        2. Configuring a DMA controller
        3. Register-based DMA
        4. An Autobuffer example
        5. Descriptor Models etc.

    Is there any video tutorials or Engineering/Application note to understand these topics.

    Please let me know if any of them are available

    Thanks and Regards,

  • Hi Srinivas,

    You can refer the same HRM to get start with DMA controller. Please refer "Direct Memory Access" Chapter in pg.1296 here you can get all information about DMA configuration, DMA channel list ,DMA Operating modes and their programming models.

    I would also, suggest you to download the below BSP of ADSP-21569, where you can get example codes.

    Path to codes: Analog Devices\EV-2156x_EZ-KIT-Rel2.0.0\EV-2156x_EZ-KIT\Examples\services\mdma
    Let me know if you have any questions.
