  • Technique for creating extended bit timer on a time processing unit
    Patent number: 7020231
    Abstract: A technique for implementing an extended bit timer with a time processing unit (TPU), without using the channel hardware of the TPU includes a number of steps. A timer of the TPU is periodically read to determine the value of the timer. A counter is incremented when rollover of the timer has occurred and a coherency flag is de-asserted after the timer transitions through a first count. The coherency flag is asserted after the value of the timer transitions through a third count and the value of the timer is combined with the value of the counter to provide a current count. When the coherency flag is asserted and the value of the timer is equal to or between the first and second counts, the current count is adjusted.
