    Allen Black
    Hi Rajat, I am trying to do something similar to what Daffiko is doing in this thread / question. You mention that Daffiko should be able to find an example of an EDMA copy implemented in the DM8127 IPNC RDK. I have attempted to find and understand an example that I can use with the DM8127 example...

    Jonathan Journo
    Hello, I am working on a DM814x chip and I have encounter a problem. Hopping anyone have found solutions....:-) We need to access the GPMC bus from the C674x directly but unfortunately the GPMC memory is not mapped to the C674x core. We could not read the data through the ARM and pass it to the DSP...

  • Forum Post: Is there any suitable device simulator for C674x core of DM8148?

    Cai Jin
    I want to do some application optimazation with EDMA and CACHE. The C674x core of DM8148 is of L1P/L1D 32KB and L2 256KB. My algorithm code size is about 500KB, and it needs about 20MB stack and heap size. So, I must take advantage of the EDMA and CACHE to optimize the algorithm implementation for the...
