Interrupt Routine Trade-off

• Although interrupt routines should be short they shouldn't be too short.

  • Interrupt routines usually cause a call to some RTOS routines to pass messages or activate semaphores.
  • RTOS routines are generally costly to execute.
  • Exceedingly small interrupt routines can therefor consume too much computational power by causing too many RTOS calls.

• Try for the balance of this trade-off
