I get slightly worse performance on rmx500_perf using this patch as compared to using the rhx100 mtune. Do you know why? Can you look into it?
added pipeline support for rmx500 to be taken into account while doing instruction fusion it is enabled by -mtune=arc-v-rmx-500-series Signed-off-by: Alex Turjan <turjan@synopsys.com>

I looked into it and it has to do with the change in the number of iterations inside the testing environment. This implies that there is a runtime behavior. For 100 iterations there improvements were slightly better for rmx500. But when the number of iterations went to 150 the rhx100 got slightly better. |
