Apparatus and method for speculative conditional move operation

Abstract:

An apparatus and method for a speculative conditional move instruction. A processor comprising: a decoder to decode a first speculative conditional move instruction; a prediction storage to store prediction data related to previously executed speculative conditional move instructions; and execution circuitry to read first prediction data associated with the speculative conditional move instruction and to execute the speculative conditional move instruction either speculatively or non-speculatively based on the first prediction data.
