METRICS
Runtime (RDTSC) [s] time
Runtime unhalted [s] FIXC1*inverseClock
Clock [MHz] 1.E-06*(FIXC1/FIXC2)/inverseClock
CPI FIXC1/FIXC0
L1I request rate PMC0/FIXC0
L1I miss rate PMC1/FIXC0
L1I miss ratio PMC1/PMC0
LONG
Formulas:
L1I request rate = L1I_READS / INSTR_RETIRED_ANY
L1I miss rate = ICACHE_MISSES / INSTR_RETIRED_ANY
L1I miss ratio = ICACHE_MISSES / L1I_READS
