RTOS/TM4C129XNCZAD: TI-RTOS response times

Part Number: TM4C129XNCZAD

Tool/software: TI-RTOS

For their products, RTOS vendors often provide maximum interrupt latencies, highest interrupt priority used, and maximum interrupt-to-task-reinstatement times.  Does TI do this for TI-RTOS?  For the above target, I would like to know if TI-RTOS ever disables ALL interrupts while running, if so, for how long, and, if not, what the maximum interrupt priority is for which TI-RTOS disables interrupts.  I would also like to know the time from an interrupt service routine task reinstatement request until the task runs, assuming it is the highest-priority task which is next on the queue to run.  If you can point me to a document to download, I'll be happy to read it.

  • Hi Leo,

    Look in the Documentation Overview (in the <install_dir>\docs directory. Go to the kernel release notes and look for the link to benchmarks. Here we have all the devices we support. Go to the "Times" for M4F. You'll see the post maximum interrupt latency for the kernel (see pic below). This same page has lots of other timing.

    There are more details about these pages in the Appendix of the SYS/BIOS User Guide (accessible from the documentation overview page).

  • This was the information I was looking for. Good work.
