Formulas:
|
||
|
|
Load ops spec. ratio = LD_SPEC / INST_SPEC
|
||
|
|
Store ops spec. ratio = ST_SPEC / INST_SPEC
|
||
|
|
Integer data ops spec. ratio = DP_SPEC / INST_SPEC
|
||
|
|
Scalar FP ops spec. ratio = VFP_SPEC / INST_SPEC
|
||
|
|
Vector FP ops spec. ratio = ASE_SPEC / INST_SPEC
|
||
|
|
Other ops spec. ratio = (INST_SPEC-LD_SPEC-ST_SPEC-DP_SPEC-VFP_SPEC-ASE_SPEC) / INST_SPEC

This group gives information about the speculative execution of micro-ops.
|
||
|
|
It is currently unclear why Other ops spec. executed and ratio is negative
|
||
|
|
in some cases. Although the documentation contains an OP_RETIRED, there is no
|
||
|
|
equivalent OP_SPEC which could be a better reference in this group instead of
|
||
|
|
INST_SPEC.
