Configure and run the MB profiler.
Syntax
mbprofile [options]Configure and run the MB profiler, a non-intrusive profiler for profiling the application running on MicroBlaze. The output file is generated in gmon.out format. The results can be viewed using the gprof editor. In case of cycle count, an annotated disassembly file is also generated clearly marking the time taken for execution of instructions.
Options
| Option | Description |
|---|---|
-low <addr>
|
Low address of the profiling address range. |
-high <addr>
|
High address of the profiling address range. |
-freq <value>
|
MicroBlaze clock frequency in Hz. Default is 100 MHz. |
-count-instr
|
Count number of executed instructions. By default, the number of clock cycles of executed instructions are counted. |
-cumulate
|
Cumulative profiling. Profiling without clearing the profiling buffers. |
-start
|
Enable and start profiling. |
-stop
|
Disable/stop profiling. |
-out <filename>
|
Output profiling data to file. <filename> Name of the output file for writing the profiling data. If the file name is not specified, profiling data is written to gmon.out. |
Returns
Depends on options used. -low, -high, -freq, -count-instr, -start, -cumulate Returns nothing on successful configuration. Error string, in case of error.
-stop: Returns nothing, and generates a file. Error string, in case of error.
Examples
mbprofile -low 0x0 -high 0x3FFFConfigure the mb-profiler with address range 0x0 to 0x3FFF for profiling to count the clock cycles of executed instructions.
mbprofile -startEnable and start profiling.
mbprofile -stop -out testgmon.outOutput the profile data in testgmon.out.
mbprofile -count-instrConfigure the mb-profiler to profile for entire program address range to count the number of instructions executed.
