TI RTOS interrupt latency on CC3200

Other Parts Discussed in Thread: CC3200, SYSBIOS

Hello,

I am designing a product based on the CC3200 (running at 80MHz).

Can anyone tell me what TI's kernel interrupt latency is? I have looked all through the documentation and cannot find any references to it.

Thanks,

Mark,

The RTOS kernel benchmarks are part of the SYS/BIOS kernel that is the foundation of TI-RTOS. They are provided with each release. If you have TI-RTOS installed, look in the tirtos_your-version/products/bios_your-version/packages/ti/sysbios/benchmarks directory. An online version is here:

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/bios/sysbios/6_42_03_35/exports/bios_6_42_03_35/packages/ti/sysbios/benchmarks/doc-files/benchmarks.html

and specifically see the M4 results, which are generated on the CC3200:

The source code is provided so you can see how the measurements are actually made.
