Abstract:
1. Apparatus for use in a system coupled to a bus, the system issuing local requests, a local request requiring corresponding associated information in order to be serviced, the apparatus comprising: a local memory for storing some of said associated information, said associated information necessary to complete a given local request, such that for each given local request, said associated information is either present in the local memory or must be retrieved via a bus request; an output request queue coupled between the local memory and the bus for storing bus requests; a bypass path element coupled between the local memory and the bus, in parallel with the output request queue, for forwarding bus requests between the local memory and the bus, a first end of the output request queue and a first end of the bypass path element each connected to the local memory, a second end of the output request queue opposite the first end of the output request queue and a second end of the bypass path element opposite the first end of the bypass path element each in communication with the bus; logic for servicing local requests, the logic operable for each local request by controlling the output request queue and bypass path element operations as follows:
