SHORT Instruction cache miss rate/ratio
EVENTSET
PMC0 INST_RETIRED
PMC1 CPU_CYCLES
PMC2 L1I_CACHE
PMC3 L1I_CACHE_REFILL
METRICS
Runtime (RDTSC) [s] time
Clock [MHz] 1.E-06*PMC1/time
CPI PMC1/PMC0
L1I request rate PMC2/PMC0
L1I miss rate PMC3/PMC0
L1I miss ratio PMC3/PMC2
LONG
Formulas:
L1I request rate = L1I_CACHE / INST_RETIRED
L1I miss rate = L1I_CACHE_REFILL / INST_RETIRED
L1I miss ratio = L1I_CACHE_REFILL / L1I_CACHE
