Abstract
In computer input-output systems contention occurs when two or more peripheral devices make interrupt requests simultaneously. The currently used methods for resolving this contention are outlined, and an improved method which avoids their drawbacks is presented. Synchronous and asynchronous implementations are described, and the effects of bus propagation time are discussed.Keywords
