Abstract
A method and apparatus for generating an interrupt signal. A counter value is decremented each time a task is completed by a slave processor. The counter value is incremented each time a task is read by the slave processor. A delay value is set using the counter value. An interrupt is generated after a period of time set by the delay value has passed. The counter value is compared to a threshold value. The interrupt is generated upon detecting a condition in which the counter value is less than the threshold value or when the completion queue is full instead of after the period of time.
