  • Patent number: 7035999
    Abstract: A register window fill technique for a retirement window having an entry size less than a number of fill instructions used in a fill condition is provided. The technique uses modified fill instructions that allow the retirement window to retire a portion of the fill instructions without having to determine whether a remaining portion of the fill instructions will execute without exceptions.
    Type: Grant

  • Publication number: 20030221088
    Abstract: A technique for flattening architectural register windows into flattened space depending on a current window pointer to a register window is provided. The technique involves converting an n-bit value of a particular register in a register window to an x-bit value dependent on the current window pointer, where x is greater than n, and where the x-bit value is used for register dependency checking among a plurality of instructions.

  • Publication number: 20030191885
    Abstract: A technique for operating a cache memory in one of multiple modes is provided. The technique involves using an fuse dependent control stage to control the generation of read and write enable signals to redundantly implemented tag and data arrays such that a portion of the cache memory may be effectively used even if another portion of the cache memory is defective due to malfunction, yield issues, process variations, etc.
