Hello,

I want to know some information that how to develop example communication between ARM and DSP, ARM and SRIO.

ARM <-> DSP : send message from ARM to DSP and from DSP to ARM

ARM <-> SRIO : send message from ARM using SRIO

Thanks & Regards,

Hi,

Find the details at the below wiki for Communication between ARM & DSP:
http://processors.wiki.ti.com/index.php/MCSDK_UG_Chapter_Developing_Transports

See the below E2E post discussion to get more detailed info,

Park MinKeun,

Please check the latest MCSDK, the IPC_3 version of package supports for communication between ARM to DSP and DSP to DSP.
The IPC_3.22.2.11(Inter-process communication) supports between DSP-DSP and ARM-DSP (ARM/DSP portion).

The image processing application shows implementation of an image processing system using a simple multicore framework.
IPC Based: The IPC based demo uses SYS/BIOS IPC to communicate between cores to perform an image processing task parallel.

The IPC in this context is MessageQ based IPC between ARM to DSP .
This transport is based on rpmsg for communication between ARM and DSPs.
A proprietary shared memory protocol for communication between DSPs.
MessageQ is a reliable control path for inter-processor communication.

Park MinKeun,
Please see this E2E thread & find the basic details of how MessageQ is handled for DSP-DSP communication over IPC.
