Texas Instruments provides full timing benchmarks with each version of the product for all the cores that are supported. Shown on this slide is a subset of these timing benchmarks. The interrupt latency which is 156 for the 28x core in the default mode can be seen in the table, but it can be thirty five if the low interrupt latency model is used, and eighty two on the -M3 or zero if the zero-latency option is applied. Also shown is the Interrupt to Blocked Task time, which is 606 cycles on the 28x and 553 on the -M3, as well as the length of time it takes from a semaphore pend on one task to resume execution on the separate task.
