Abstract
A method for determining whether a bus interface should immediately acknowledge a read request. In one embodiment, devices connected to a plurality of buses are assigned addresses from a first set of addresses or a second set of addresses depending upon whether the device will accept a read request within a predetermined period of time. The bus interface immediately acknowledges a read request directed toward a device with an address in the first set of addresses and delays the acknowledgement for a read request directed toward a device with an address in the second set of addresses.
