IPC messaging latency for OMAPL138 board

Hi all,

I am trying to find latency for IPC message passing, with omapl138 based board, using the sample application provided by IPC 3.00.01.24(messageq_single.c). I have attached the sample application(Linux side MessageQApp.c) in the post.

With this application, I am getting 3mSec as round trip time and 1.5mSec as one trip time. Is the latency for messaging takes time in order of milliseconds? If some one has measured the latency please let me know. Even it is for some other Multi Core SoC is fine.

Thank you :)
