Performance Analysis
Your TA700/800 offers you two ways to do Performance Analysis, Real-time and
statistical. Performance Analysis that may be performed in any of the TA700/800
working modes except the Timing and Timing Asynchronous.
Exerciser Program When operating in the State Analyzer & Exerciser working mode, 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 TA700/800 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 796MB/Sec,
64-bit 100 MHz. The analysis measurements are taken in accordance with predefined
analysis projects (*.pap). 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.
