Abstract: A method of detecting sequential data transfer requests, includes determining whether a first data transfer request crosses a boundary address, and, if it does, determining if the first data transfer request may be indicated as combinable with subsequent data transfer requests. The method may also include determining whether a previous data transfer request has been indicated as combinable, and if it has been indicated as combinable, determining that a new data transfer request is addressed adjacent to the previous data transfer request.

Abstract: A method of coalescing transfer requests, includes storing a transfer request on a pending list, determining that no previous transfer requests are being processed, combining at least two transfer requests as a combined data transfer and releasing the combined data transfer. The method may also include determining that the pending list is not empty before releasing the combined data transfer.

Abstract: In one embodiment, a method is provided. The method of this embodiment may include determining whether requested data is stored in a memory. If the requested data is not stored in the memory, the method may include determining whether a plurality of requests to access the requested data have occurred during a predetermined number of most recent data accesses. If the plurality of requests to access the requested data have occurred during the predetermined number of most recent data accesses, the method may also include storing the requested data in the memory. Of course, many variations, modifications, and alternatives are possible without departing from this embodiment.

Abstract: A control system is described for controlling the flow of multi-format, multi-bit macroinstructions for loading data into registers. The control system is adapted to: (A) control microprogram flow of instructions based on data within a floating point macroinstruction, (B) speed up macroinstruction flow as a function of data within various fields of the macroinstruction, and (C) speed up macroinstruction branches.
