(2) AUD Performance Analysis Function (AUD Performance Analysis)
The emulator allows you to measure the time or count of execution between specified events in the
AUD event detection system. It is possible to set the resolution of the timer to any of the following
values:
20 ns, 40 ns, 100 ns, or 400 ns.
At 20 ns the maximum time that can be measured is about six hours, and at 400 ns the maximum
time is about five days.
(3) External Bus Performance Analysis Function (BUS Performance Analysis)
The emulator allows you to measure the time or count of execution between specified start and
end conditions. It is possible to set the resolution of the timer to any of the following values:
20 ns, 50 ns, or 400 ns.
At 20 ns the maximum time that can be measured is about six hours, and at 400 ns the maximum
time is about five days.
(4) Profiling Function (Profile)
The profiling function is used to measure the performance of each function.
A function having low performance can be easily found if the statistics of the time for each
function are maintained.
Items that can be measured are the same as those for the on-chip performance measurement
function.
Notes: 1. Use of the profiling and on-chip performance analysis functions at the same time is not
possible. The [Can not use this function] error message dialog box will be displayed if
simultaneous use is attempted.
2. In this function, a break occurs whenever a branch is generated, and information is
collected to execute the user program again. Therefore, realtime emulation of the user
program will not be performed.
