A process for maximizing the instruction processing efficiency of a digital computer for the purpose of calculating rotational speed wherein the calculation of speed is based upon speed signals generated by a tachometer. By (1) counting the quantity of the speed signals received during a fixed sampling period, and (2) recording the occurrence time of these speed signals only as necessary for the calculation of rotational speed, the invention improves over known methods in that it does not record the occurrence time of all speed signals, but rather records the occurrence time of only those speed signals necessary for the calculation. The invention accomplishes this by a) anticipating when the speed signals necessary for the speed calculation will be generated (and subsequently received by the digital computer) and b) recording the occurrence times only when it is anticipated that these necessary edges will be received by the digital computer. |
