Pharos


DESCRIPTION

Pharos is a free open-source RTOS for secure, safe and real-time systems with the following characteristics:

- Memory and enhanced time partitioning (TSP)
- Native support for sporadic, periodic and aperiodic threads
- Fixed-priority preemptive scheduler
- Execution time protection (threads are prevented from executing for more time than they are configured to)
- Small size (full image has ~100 to 300KiB text, ~30KiB data)
- Hard real-time determinism
- Fast critical sections
- Prioritized nested interrupts
- inter-partition communication with filters to protect unwanted access
- Multicore support (RMP)
- Supports ARM9, Cortex-A/R/M and Aarch64, RISC-V64 (64 bits)
- The complete TestSuite (see below information) is run successfully for each platform in each release
- Tested: more than 170 KLOC of requirement-based tests, executed for each board at each release
- Up-to-date User Manual also available

See our wiki page for more information.
