  • Predecode repair cache for instructions that cross an instruction cache line
    Patent number: 8898437
    Abstract: A predecode repair cache is described in a processor capable of fetching and executing variable length instructions having instructions of at least two lengths which may be mixed in a program. An instruction cache is operable to store in an instruction cache line instructions having at least a first length and a second length, the second length longer than the first length. A predecoder is operable to predecode instructions fetched from the instruction cache that have invalid predecode information to form repaired predecode information. A predecode repair cache is operable to store the repaired predecode information associated with instructions of the second length that span across two cache lines in the instruction cache. Methods for filling the predecode repair cache and for executing an instruction that spans across two cache lines are also described.
