SHORT Instruction cache miss rate/ratio

EVENTSET
PMC0  INSTRUCTIONS_RETIRED
PMC1  ICACHE_FETCHES
PMC2  ICACHE_REFILLS_L2
PMC3  ICACHE_REFILLS_MEM

METRICS
Runtime (RDTSC) [s] time
L1I request rate   PMC1/PMC0
L1I miss rate    (PMC2+PMC3)/PMC0
L1I miss ratio   (PMC2+PMC3)/PMC1

LONG
Formulas:
L1I request rate = ICACHE_FETCHES / INSTRUCTIONS_RETIRED
L1I miss rate = (ICACHE_REFILLS_L2+ICACHE_REFILLS_MEM)/INSTRUCTIONS_RETIRED
L1I miss ratio = (ICACHE_REFILLS_L2+ICACHE_REFILLS_MEM)/ICACHE_FETCHES
