Abstract
A multi-module network having dual system busses using a common bus protocol which supports processor modules using a store-through cache memory and processor modules using a non-store-through cache memory which includes interface modules including a spy unit for maintaining cache coherency and arbiter modules so that any particular module is not starved out. A maintenance processor organizes the network as a joined system where both the store-through and non-store through processor units can utilize either one of the dual system busses or a split system where one bus is dedicated to the store-through processor units and one bus is dedicated to the non-store through processor units.
