Performance Analysis
Your TA660 offers you two ways to do Performance Analysis, Real-
time and statistical. Performance Analysis may be performed in any
of the TA660 configurations.
Exerciser Program When operating in the State Analyzer & Exerciser
configuration, an exerciser program is required to generate
bus traffic.
Real-time analysis uses hardware counters and dual ported FIFOs.
The counters count the events at all times and interface with CPU via
the FIFO to pass the results. This method results in the most accurate
performance measurement since the counters are never stopped to be
read.
ADVANTAGE: Continuous Real-time measurement.
DISADVANTAGE: Measurement results are based on an
average. Minimum and maximum can
not be measured and reported in this
mode.
Statistical analysis is done by capturing the data
into memory and post processing it by software. In this mode TA660
allows the capture to occur after an occurrence(s) of events so the
captured data would include mostly the desired transactions and not
unrelated bus activities.
ADVANTAGE: Many more measurements are
possible than in the Real-time method.
It is possible to measure Min, Max
and Average counts.
DISADVANTAGE: Non Real-time, Software post
processing the data.
Real-time Analysis
Continuous, Real-Time Analysis measures bus performance of up to
533 MB/Sec, 64-bit 66MHz. The analysis measurements are taken in
accordance with predefined analysis projects (*.pep). Some
predefined analysis projects are included with your software for
immediate use or, you may create your own custom analysis projects
by setting analysis options, creating analysis equations, event patterns
and exerciser programs.
