Abstract
An arbiter apparatus for selecting an agent to use a shared resource such as memory. A normal round robin list is utilized in the selection process during boot operation. During the initialization process, a dynamic list is generated in accordance with system requirements. The dynamic list selection process may take any of several forms. In a first mode, it may select only priority listed agents, any one of which may be repeated during a given cycle of selection. In a second mode, it may select a designated buddy agent when the selected priority agent is idle. In either mode, and in accordance with a set of priority selection rules, one or more lowest priority default agents may be given access when the designated higher priority agents for a given list entry slot are idle.
