Major Functions of Simulator Memory System Analysis
9.1 Major Functions of Simulator Memory System Analysis
The ’C6x memory system analysis functionality allows you to set breakpoints
on or count any event that is supported by the simulator core. These events
are added to the Analysis Events dialog box by polling the simulator core to
determine which events it can support.
The ’C6x memory system analysis interface allows you to set breakpoints on
or count the following events, which are supported by the ’C6x:
- Program memory accesses
- Program cache hits
- Program cache misses
- Memory stalls
- Off-chip program memory accesses
- Off-chip data memory accesses
- Data memory bank conflicts
You can set breakpoints on or count multiple events.
Set up event breakpoints
’C6x memory system analysis enables you to set breakpoints on system
events. These events are called break events. You can break on any of the
events supported by the ’C6x core, and you can set a breakpoint on one or
more of these events.
Break events are automatically counted by the event counter. Each break
event is displayed in the Analysis Statistics window, along with the number of
times that break event occurred during each execution of the program, the program address on which the last breakpoint occurred, and the name of the routine in which the breakpoint occurred.
Count system events
You can set up memory system analysis to count occurrences of system
events during the execution of your program. You can count any single event
or any combination of events supported by the ’C6x. Each event that you select
to count is displayed in the Analysis Statistics window, along with the number
of times that event occurs during the execution of your program.
You can use all of the basic debugger step and run commands to determine
the number of occurrences of each selected event that you want to count. The
event counters keep incrementing with each execution of your program unless
you select the Reset Counter button on the Analysis Statistics window. When
you select the Reset Counter button, each of the event counters resets to 0
immediately.
