DSP/BIOS Link performance

Hi all,

I'm using DSP/BIOS Link 1.63 on an OMAPL137.

My message queue transport is shared memory, zero copy.

It takes only 60 us for the DSP to send the message with MSGQ_put, but it takes almost 5 ms before the ARM receives the message with MSGQ_get.

Any ideas what's taking so long?

 

Thanks for your reply!
