Abstract
In a bus-oriented computer system, the decision as to which unit is to receive the bus takes account of the current status of the bus system and the respective operation to be performed on the bus. For that purpose, status information of the connected units, the bus command to be executed and the address of the requested unit are fed to the allocation logic (arbiter) on separate or commonly used lines, thus avoiding idle times during the use of the bus. By evaluating the bus command, the allocation priority can be dynamically changes in order to suppress bus accesses that are bound to fail from the start.
