DSPLink Latency

Other Parts Discussed in Thread: OMAP3530

Hello,

1)  I currently have the DSPLink "Loop" project supplied by TI running on an OMAP3530 using the Mistral EVM.  The version of "Loop" running is the task based version with a 1K byte buffer size.  Using this buffer size I'd like to know what the lowest achievable round trip time I can expect.  I'm currently measuring a round trip time of between 350us - 720us and this seems excessive.   

2) What kind of performance can I expect from the SWI version of the "Loop" project using the same buffer size?

 

Thanks,

Len
