3.9
Use the performance analysis function to measure the rate of execution time. The performance analysis function
does not affect the realtime operation because it measures the rate of execution time in the specified range by
using the circuit for measurement of hardware performance included in the emulator.
Select one of the following five modes according to the purpose of measurement.
Table 3.1
Use eight performance channels installed on the circuit for measurement of hardware performance in the
emulator for setting of conditions for measurement. Up to eight points can be set.
Note, however, that up to four points can be set in Start Range To End Range Measurement, Access Count Of
Specified Range Measurement, or Called Count Of Specified Range Measurement because two sequential points
are used for setting a condition in these modes.

Description
Measures the execution time and
execution count in the specified
range.
Measures the execution time and
execution count between the
specified addresses.
Measures the execution time
from a specified range to another
specified range.
Measures the number of times a
specified range is accessed from
another specified range.
Measures the number of times a
specified range has called
another specified range.
Purpose
Measurement of time taken for
processing of functions except for
that required for child functions
called from the functions.
Measurement of time taken for
processing of functions.
Measurement of execution time
spent from calling of any of
sequential subroutines to calling of
any of other sequential subroutines
in a program that includes
subroutines in sequence, such as
an assembly program.
Measurement of the number of
times a global variable is accessed
from a specific function.
Measurement of the number of
times a function is called from a
specific function.
