Abstract: An interface system for transferring information between a local area network and a system memory associated with a station attached to the network. The interface system includes a bus interface unit for implementing the transfer of information between the interface system and the memory system. An indicate module transfers information received by the interface system from the network to the memory system via the bus interface unit. A request module transfers information received by the interface system from the memory system via the bus interface unit to the network. A status generation/space management module connected to the indicate module and to the request module monitors the status thereof and generates corresponding status signals and manages the allocation of storage space in the memory system for information transferred between the network and the memory system via the interface system.

Abstract: A high performance shared-bus signal detection mechanism comprises a plurality of access event registers, an address comparator, an event masking component, and a local processor access detector. The comparator component couples to a bus providing access to a shared memory address space. The bus can be used by a single processor or shared by a plurality of processors. A processor loads the address event registers with address base and extent values and type of access notification desired. As addresses and access-type signals appear on the bus, the comparator simultaneously compares the bus information to access event register information to determine if the bus access meets access event register criteria. When matches occur, the comparator emits an appropriate signal to an event masking component. The local processor also loads the event masking component to selectively mask off unwanted event notifications as well as those performed by itself.
