Abstract
A method and circuit arrangement speculatively preprocess data stored in a register file during otherwise unused cycles in an execution unit, e.g., to prenormalize denormal floating point values stored in a floating point register file, to decompress compressed values stored in a register file, to decrypt encrypted values stored in a register file, or to otherwise preprocess data that is stored in an unprocessed form in a register file.
