Abstract
The invention provides a system and method which can be used for pre-decoding one-byte instruction prefixes and branch instruction indicators. A static line detect generates a number of instruction indicators. Further, a prefix and branch decode unit combines at least two of the number of instruction indicators, and a pre-decode unit decodes the combined instruction indicators. Embodiments of the invention decode one byte prefixes without additional cycle penalty and generate one and two byte branch indications early.
