Core Partitioning
 

Core Partitioning

Shared Mode (Host OS and RTOS share a single core)

  • Used on single core processors
  • RTOS ISRs/Tasks always have priority over Hypervisor Host OS
  • RTOS execution unaffected by Host OS interrupts and exceptions
  • API to force RTOS immediately transferring back to Host OS
  • Available on multi core processors as well
Exclusive Mode
  • Used on multi core processors
  • RTOS operation is completely independent from the Host OS
  • Extremely short RTOS latency: no OS transition necessary
  • Modes and usage of cores can be easily re-configured
