Abstract
A bus interface priority network provides access to a system bus by a plurality of different types of requestors as a function of the types of transactions they are required to process. The network includes programmable circuit for identifying the type of requestor and selecting a delay for accessing the system bus on the basis of requestor type thereby eliminating the need to adjust timing to the slowest requestor.
