```
Then run the Vitis analyzer on the summary file, for example, `xclbin.ex.run_summary`
The following is the snapshot of the time trace for the LeNet design run.

Throughput calculation is as follows:
```
Difference in timeline (execution time) = 5097.847us
Throughput = no of images / execution time
= 100 / 5097.847us
= 19,617 images/s
The excution time reported by trace is with the data mover kernel running at 150MHz. Since the data mover kernel is running at 250MHz, we need to scale the execution time. Hence,
Throughput = 19,617 images/s x (250 / 150 ) = 32,695 images/s
```
