Apparatus for generating a channel time-out signal after 16.38 milliseconds |
摘要 |
An apparatus and method for processing channel time-out for input/output channels in a data processing system. A counting device is provided which cycles through a count indicative, in a first part, of each of a plurality of channels in the data processing system and, in a second part, a sequence of time indications. A time indication is saved for a particular channel upon the execution of an instruction for that channel and subsequent comparisons are made of the stored time indication and the present time indication to determine if a difference in these two time indications is sufficient to constitute a time-out. |
