Does accelerator time contains memory transfer time?

Hi,
 
In the SNPE doc (benchmarking chapter), 'Accelerator' is explained as: measures the total execution time spent on the accelerator core, which may include different resources.
 
My question is: does it measures computational and memory time altogether? Or computational time only?
Thanks!

Refering to the document here:

https://developer.qualcomm.com/docs/snpe/benchmarking.html

Detailed metrics are provided for init and execution steps. Use '-l detailed' (detailed profiling level). Execution processing metrics include "Total Inference Time ". Quoting from the document:

  • Total Inference Time measures the entire execution time of one inference pass. This includes any input and output processing, copying of data, etc. This is measured at the start and end of the execute call.

 

Time taken for memory operations is accounted here
