A method for converting a distance of dependency (DoD) value to a cycle of dependency (CoD) value is disclosed. The method comprises the steps of (i) simulating a dependency system timer (DST) on a data processing system, with the DST having a present time measured in cycles and a period, (ii) adding a DoD value of N bits to the present time to yield a resulting time of the least significant N bits of said adding step, and (iii) creating the CoD value by appending a carry over of the adding step to the resulting time, where when the carry over is not equal to zero, the carry over signals a user of the CoD value to wait until a next period before the CoD value should be applied. In one embodiment, the carry-over value is added to the value corresponding to a respective alternating period to yield an even/odd bit which determines the period. |
