Hi all,
Iam trying to measure the performance cycles for my application on RVISS ARM1176JZF-S platform.
When I measure the cycles it is giving 471977 cycle counts,
But measuring the same application performance on different machine it is giving 423787 cycle counts (lesser than my measurement).
For measuring the performance cycles on my machine, I followed some steps of settings:
MCCFG=1 in default.ami file and given ICACHE_LINES, DCACHE_LINES to 1024.
but sitll Iam getting difference of 48190 cycles, why this difference of cycles is getting in my machine?
Is I need to set more settings other than above?
Please help me in this.
Thanks in advance,
Vinay.
