PERFORMANCE-MONITORING EVENTS
10H
01H
FP_COMP_OPS_EXE.X87
Counts the number of FP Computational Uops
Executed. The number of FADD, FSUB, FCOM,
FMULs, integer MULs and IMULs, FDIVs, FPREMs,
FSQRTS, integer DIVs, and IDIVs. This event does
not distinguish an FADD used in the middle of a
transcendental flow from a separate FADD
instruction.
10H
02H
FP_COMP_OPS_EXE.MMX
Counts number of MMX Uops executed.
10H
04H
FP_COMP_OPS_EXE.SSE_FP
Counts number of SSE and SSE2 FP uops executed.
10H
08H
FP_COMP_OPS_EXE.SSE2_INT
EGER
Counts number of SSE2 integer uops executed.
10H
10H
FP_COMP_OPS_EXE.SSE_FP_P
ACKED
Counts number of SSE FP packed uops executed.
10H
20H
FP_COMP_OPS_EXE.SSE_FP_S
CALAR
Counts number of SSE FP scalar uops executed.
10H
40H
FP_COMP_OPS_EXE.SSE_SING
LE_PRECISION
Counts number of SSE* FP single precision uops
executed.
10H
80H
FP_COMP_OPS_EXE.SSE_DOU
BLE_PRECISION
Counts number of SSE* FP double precision uops
executed.
12H
01H
SIMD_INT_128.PACKED_MPY
Counts number of 128 bit SIMD integer multiply
operations.
12H
02H
SIMD_INT_128.PACKED_SHIFT Counts number of 128 bit SIMD integer shift
operations.
12H
04H
SIMD_INT_128.PACK
Counts number of 128 bit SIMD integer pack
operations.
12H
08H
SIMD_INT_128.UNPACK
Counts number of 128 bit SIMD integer unpack
operations.
12H
10H
SIMD_INT_128.PACKED_LOGIC
AL
Counts number of 128 bit SIMD integer logical
operations.
12H
20H
SIMD_INT_128.PACKED_ARITH Counts number of 128 bit SIMD integer arithmetic
operations.
12H
40H
SIMD_INT_128.SHUFFLE_MOV
E
Counts number of 128 bit SIMD integer shuffle and
move operations.
13H
01H
LOAD_DISPATCH.RS
Counts number of loads dispatched from the
Reservation Station that bypass the Memory Order
Buffer.
13H
02H
LOAD_DISPATCH.RS_DELAYED Counts the number of delayed RS dispatches at the
stage latch. If an RS dispatch cannot bypass to LB, it
has another chance to dispatch from the one-cycle
delayed staging latch before it is written into the
LB.
13H
04H
LOAD_DISPATCH.MOB
Counts the number of loads dispatched from the
Reservation Station to the Memory Order Buffer.
13H
07H
LOAD_DISPATCH.ANY
Counts all loads dispatched from the Reservation
Station.
