System Performance Analysis (SPA) Software
SPA measurement processes
Example
Time Interval example
A team of applications programmers is writing a math package for a
spreadsheet. They need to develop standards for the various math functions.
Using time interval mode, they can test the execution time of each of the
math functions.
For each math function, they enter the starting and ending addresses in the
Time Interval menu. They run the math function while monitoring its
execution time with their logic analyzer in the Time Interval mode. Using
Auto-range, they can quickly vary the time interval ranges for either greater
time coverage or greater time resolution.
If the programmers wanted to see the details of the time intervals, they could
set up a state analyzer measurement (not using SPA) and capture the activity
between the start and stop events. The details could then be viewed in the
state listing menu.
The figure below shows a sample Time Interval menu and its display.
