ABSTRACT:
A method of operating a timer mechanism in a digital data processing system is described in which the contents of at least one timer register is updated by a predetermined time increment during each of successive periodic update cycles. Each update cycle includes a predetermined number of operating cycles of the data processing system. During each update cycle, the contents of an adjustment register is circularly shifted by one bit position and if the bit value at a particular position in this adjustment register has a predetermined binary value during an update cycle, then actual updating of the timer register is omitted during a related update cycle.
