Performance Analysis

Performance Analysis (Advanced Mode)
Conquest M2 has two ways to do Performance Analysis: Real-time and
Statistical Trace analysis.
Real Time analysis uses hardware counters and dual ported FIFOs. These
counters continually count the events and interface with the CPU via the FIFO
to pass the results. This method results in the most accurate measurement,
since the counters never stop for reading.
Advantage
Continuous Real-Time measurement.
Disadvantage Measurement results are based on an average.
Minimum and maximum cannot be reported in this mode.
Statistical Trace analysis is done by capturing the data into memory and then
post processing it with software. In this mode, Conquest M2 allows capture to
occur after an occurrence(s) of events such that the data includes mostly
interesting transactions and not unrelated bus activity.
Advantage
Many more measurements are possible than in the
Real-Time analysis. It can measure Min, Max, and Average
counts.
Disadvantage Non-Real-Time software post-processing of data.
Real Time Analysis
To do a Real-Time performance analysis, open an existing project file or
define a new analysis project by defining:
•
Packets to use in the analysis
• An Exerciser program, to measure performance with specially generated
bus traffic
• An analysis expression or expressions, to measure multiple performance
parameters
• Results display configuration
• Performance analysis project options
