Hi all,

My customer want share buffer between dsp and arm. it's about 200KB buffer.

What's the suggestions?

Share region or CMEM or Ring buffer?

Customer can accept static memory.

thanks!

    Hello Denny,

    It depends on your customer's use case (e.g. if there are latency or throughput requirements, what the ARM-DSP interaction is expected to be, etc).

    Without knowing any additional information, I would point them to TI's Big Data IPC. You can find more information on the Inter-Processor Communication protocols TI supports in our Multiple Ways of Arm-DSP Communication documentation.

    You can find more information on AM57xx specific topics (like how to allocate memory spaces and change memory maps to match) in our IPC for AM57xx documentation.

    Regards,

    Nick
