  • Tracking a relative arrival order of events being stored in multiple queues using a counter
    Patent number: 9823952
    Abstract: An order controller calculates an absolute value of a difference between a first counter value stored with a first next entry set to an active status in a first queue from among at least two queues and a second counter value stored with a second next entry set to the active status in a second queue. The order controller compares the absolute value with a counter midpoint value. The order controller, responsive to the absolute value being less than the counter midpoint value, selects a smaller value of the first counter value of the first counter value and the second counter value as a next event to process. The order controller, responsive to the absolute value being greater than or equal to the counter midpoint value, selects a larger value of the first counter value and the second counter value as the next event to process.

  • Tracking a relative arrival order of events being stored in multiple queues using a counter
    Patent number: 9189433
    Abstract: An order controller stores each received event in a separate entry in one of at least two queues with a separate counter value set from an arrival order counter at the time of storage, wherein the arrival order counter is incremented after storage of each of the received events and on overflow the arrival order counter wraps back to zero. The order controller calculates an absolute value of the difference between a first counter value stored with an active first next entry in a first queue from among the at least two queues and a second counter value stored with an active second next entry in a second queue from among the at least two queues. The order controller compares the absolute value with a counter midpoint value to determine whether the first counter value was stored before the second counter value.
