3. Others
(a) When the profiling function is used, an internal break occurs in the execution of the user
program. Therefore, the measurement results of AUD performance analysis, bus
performance analysis, and realtime profile will contain errors.
(b) When the profiling function is used, the contents that have been set in the on-chip
performance measurement function or data that has been measured will be deleted.
(c) Since the profiling function is implemented with the internal break, it takes a long time to
start and end the user program execution. The stopping time of the user program depends
on the performance of the host machine in use or the JTAG clock; that time under the
following environment is shown below:
Environment:
Host machine: 850 MHz (Pentium
Memory: 256 Mbytes
SH7323: 10 MHz (TCK clock)
OS: Windows
Execution program: 10,000 nested calls
(i)
When the profiling function is not used: 1 second or lower
(ii) When the profiling function is used in the setting without including a child function:
63 seconds
(iii) When the profiling function is used in the setting including a child function:
72 seconds
(d) When the profiling function is used, the trace settings are internally changed and the
[Internal trace] mode is set. Note that a part of emulator functions cannot be used if the
mode is not changed to [AUD trace].
