Table B-1 Pentium 4 Processor Performance Metrics (continued)
Metric Description
Logical The number of
Processor 0 cycles that the trace
Build Mode and delivery engine
(TDE) is building
traces associated
with logical
processor 0,
regardless of the
operating modes of
the TDE for traces
associated with
logical processor 1. If
a physical processor
supports only one
logical processor, all
traces are
associated with
logical processor 0.
Logical The number of
Processor 1 cycles that the trace
Build Mode and delivery engine
(TDE) is building
traces associated
with logical
processor 1,
regardless of the
operating modes of
the TDE for traces
associated with
logical processor 0.
This metric is
applicable only if a
physical processor
supports
Hyper-Threading
Technology and have
two logical
processors per
package.
