Impact to kernel footprint and performance

Has there been any characterization to the code size impact and memory requirements for openAMP? It would be interesting to know how openAMP would impact small footprint RTOSes.

 

Understandably performance impacts are difficult to quantify, since there are numerous depenedencies and scenarios to consider. Has any level of characterization been done on this topic?

Re: Impact to kernel footprint and performance

Hi,

 

I don't know of any characterization that has been done, but it's easy enough to build the baremetal sample apps and get an idea.

 

Here's the size of the remote baremetal matrix multiply application and it seems reasonable in size.

Thanks

John
