David B Fite, John E Murray, Dwight P Manley, Michael M McKeon, Elaine H Fite, Ronald M Salett, Tryggve Fossum: Branch prediction. Digital Equipment Corporation, Arnold White & Durkee, August 25, 1992: US05142634 (188 worldwide citation)

A branch prediction is made by searching a cache memory for branch history information associated with a branch instruction. If associated information is not found in the cache, then the branch is predicted based on a predetermined branch bias for the branch instruction's opcode; otherwise, the bran ...

David B Fite, Ricky C Hetherington, Michael M McKeon, Dwight P Manley, John E Murray: Virtual instruction cache system using length responsive decoded instruction shifting and merging with prefetch buffer outputs to fill instruction buffer. Digital Equipment Corporation, Arnold White & Durkee, May 12, 1992: US05113515 (52 worldwide citation)

An instruction buffer of a high speed digital computer controls the flow of instruction stream to an instruction decoder. The buffer provides the decoder with nine bytes of sequential instruction stream. The instruction set used by the computer is of the variable length type, such that the decoder c ...

Digital Equipment Corporation, Arnold White & Durkee, August 25, 1992: US05142631 (25 worldwide citation)

A method is provided for preprocessing multiple instructions prior to execution of such instructions in a digital computer having an instruction decoder, an instruction execution unit, and multiple general purpose registers which are read to produce memory addresses during the preprocessing. The met ...
