Abstract
A control system attends to an orderly transmission of data over a time division multiplex data bus. Each time that a terminal wants to transmit data over the data bus, it files a request for data transmission with an arbiter circuit, which normally grants the requests on a first come, first serve basis. If there are simultaneous requests, the arbiter consults a table of priorities stored in its memory. The one of the simultaneous requests with the highest priority is served first. Each terminal acknowledges the data which it receives. If the acknowledgment does not come back in a timely manner, the data is retransmitted.
