Hi,

We are profiling our system using TSCH and TSCL registers. To reach to an reliable estimate, we need to measure

Number of times the context switch has occured
Average clock cycles consumed in context swith
SYSBIOS overhead details

Please convey some references, APIs using which I can compute all these. I am using 6670 Keystone DSP processor.

Thanks,

Hi,

Have you already taken a look at Appendix B of SYSBIOS userguide and BIOS_INSTALL_DIR/packages/ti/sysbios/benchmarks/doc-files/Results.html

Regards

Hi Johannes,

Thanks, I understand that values specified tell me the cycles consumed in various context switch scenarios but i would also like to find number of context switch occurred, semaphore pends and post counts that occurred in last 1 msec etc.

Regards,

Pankaj
