software

OSEK-like operating system

(used in automotive and in household appliances)

available for 16-bit Microchip microcontrollers

PIC24, dsPIC30, dsPIC33

performance:

  • preemptive fixed priority multithreading
  • EDF scheduling
  • Immediate Priority Ceiling to avoid priority inversion
  • stack sharing to reduce stack RAM usage
  • minimal footprint: < 1 Kb Flash

double licensing: GPL and commercial per seat license
