Taking advantage of the Cortex- M3. Essentially, the Sys. Tick interrupt enables round- robin style scheduling while the Pend. SV supports FIFO style.
Figure 1: Values assigned to the PSP when switching tasks When an interrupt request is serviced on the CM3, some registers (see . Software flow diagram of system routines. The context switcher is invoked only through the Sys. Tick and Pend. SV interrupt requests. Values of an initialized task stack.
Once the task. The interrupt interval is calculated by multiplying the CPU frequency by the reload value. The Pend. SV interrupt is enabled by default, and no initialization is required. Conclusion. The CM3 has many advanced features that lend themselves to creating an embedded operating system. Tyler Gilbert is the lead developer on Co.
