Task Scheduling
FreeRTOS runs a preemptive scheduler on the Zynq PS Cortex-A core: tasks switch by priority, queues and semaphores handle inter-task communication and synchronization, and ISRs defer critical events to tasks via notifications — splitting a complex project into parallel simple tasks.
