Hi Andrew,
I was testing this patch locally, and wanted to see if we get some perf
improvements with some benchmarks available on the default image. What
benchmark do you recommend testing this against?
I ran '/runLinpack/' on the tisdk-default-image on j7200 and did not see
any difference in the reported performance with and without this
patch... is this expected?
With the default image built on latest SDK, WITHOUT the patch:
Unrolled Single Precision 1845878 Kflops ; 10 Reps
With default image built WITH the patch:
Unrolled Single Precision 1857362 Kflops ; 10 Reps
Thanks,
Aniket
