Abstract
A computer system having a hierarchical bus structure that allows decoupling of a local bus from a global bus thereof. Decoupling of the local bus is achieved through use of an asynchronous system bus adapter which includes a local bus adapter for handling transactions, initiated by a system device coupled to the global bus, that require access to a local device coupled to the local bus and a global bus adapter for handling transactions, initiated by a local device coupled to the local bus, that require access to a system device coupled to the system bus. The local bus adapter is further configured to issue signals which prevent the global bus adapter from handling transactions initiated by local devices coupled to the local bus while transactions initiated by system devices coupled to the global bus are on-going.
