Overview

What it does: Robotheca's summary

  • Tasks are the unit of concurrency, triggered by asynchronous events or spawned on demand by the application.
  • Messages can be passed to software tasks at spawn time.
  • A timer queue lets software tasks be delayed or scheduled, which can implement periodic tasks.
  • Shared memory is accessed through fine-grained priority-based critical sections, avoiding data races.
  • Deadlock freedom is guaranteed at compile time.
  • The scheduler has a minimal software footprint, with the hardware doing most of the scheduling, and needs no dynamic memory allocator.
