    摘要: An improved cache memory for use with a microprocessor. A line buffer which stores a tag and offset field and the corresponding line of data is employed. Valid bits are associated with different potions of the data stored in the line buffer. Thus during a line fill, by way of example, an instruction may be read from the line buffer before the entire line is filled from main memory.

    摘要: A loop detector with an array to store a counter of loop iterations, where the number of entries in the array may be for example smaller than the number of entries in the loop detector. Entries in the array may for example be associated with more than one entry in the loop detector. The array may store for example a counter of speculative iterations of a loop or for example a number of actual iterations of a loop.

    摘要: An improvement in a microprocessor permitting the selection of write-back, write-through or write-once protocols is disclosed. A pin is connected to either ground or Vcc potential to select either the write-through or write-back protocols. When this pin is connected to the read/write line, the write-once protocol is selected. Interconnection between two processors is described which permits the processors to operate in a write-once protocol with a minimum of glue logic.

    摘要: A system, method and device for storing branch predictions in a queue that may be connected to a branch prediction unit, and for delivering the stored predictions to an instruction fetch unit. A look up may be made of for example two sequential lines, and for example a segmented cache of a branch prediction unit may generate predictions of an address having an even numbered index by referring to for example a first side of the cache, and an address with an odd numbered index by referring to for example a second side of the cache. Branch predictions for two sequential lines may be generated during for example a prediction period such as two clock cycles. In some embodiments, a next instruction pointer of a branch prediction unit may be independent or decoupled from of a next instruction pointer of an instruction fetch unit.
