Hi,
Let me talk about AM5716.
My customer want to use C66DSP for calculation.
They consider this system.
It need calculation of real time.
and We think Sequence is below:
(1)FPGA send data via GPMC to AM57x
(2)Calculation using C66DSP
(3)C66DSP feedback to FPGA
and We think Data Flow in AM57x is below:
(a)GPMC get Data and transfer data via EDMA
(b)After transfer comleate, EDMA issues an interrupt to the DSP.
(c)DSP calculate
(d)After compleate of calculation, DSP send result data to GPMC
(e)GPMC send Data to FPGA
so I have a few question.
(i)I think C66DSP can not access to GPMC directly. but C66DSP access EDMA.
Because It is described
This understanding is correct?
(ii)I beleive AM57x has capability for this system using only GPMC
and C66DSP and EDMA After initialization.
It means we do not want to use M4 and A15. Because of realtime system.
Can you give me any advice whether this system is feasible? and If you have other idea for realtime system using AM5716, Please let me know.
Best regards
Hiroyasu
