TDA4VM: Is it safe to run pre-processing node on C7x-1 for TDA4VH

Part Number: TDA4VM
Other Parts Discussed in Thread: TDA4VH

Tool/software:

Hi TI experts,

We are trying to run multiple models with one TDA4VH. We've seen this thread: TDA4VM: TDA4 High: pre-processing and post-processing nodes to run on different cores - Processors forum - Processors - TI E2E support forums, and learned that initially the C7x-1 was not expected to run pre-processing nodes. Modifications have been provoded to allow C7x-1 to run pre-processing node, but we wondering whether it is safe to run pre-processing node on C7x-1 or there's some other limitations for doing so?

Thanks and best regards

  • Hi Hui,

    As mentioned in the previous thread udma_copy is not enabled in c7x_1, for pre-proc nodes the kernels does not use udma_copy. so you can use those in c7x_1 (only pre-proc node).

    And most of the postproc kernels use udma_copy so you can run those in rest of the c7x cores, Since tidl is running in c7x_1 I would suggest to run the pre-proc and post-proc in other c7x (2,3,4) cores.

    Regards,
