Abstract
An apparatus comprises sampled state storage to store sampled values of at least one register operand sampled at a sampling point in program flow, and a correlation prediction table to store at least one correlation prediction entry, each correlation prediction entry providing at least one confidence indication for a corresponding branch instruction, and each confidence indication indicating a likelihood that a corresponding function of register state sampled at the sampling point correlates to a branch outcome for the corresponding branch instruction. The apparatus comprises prediction circuitry to make a prediction of a branch outcome for a particular branch instruction based on performing a particular function of register state sampled at the sampling point, the particular function corresponding to a confidence indication, meeting a prediction criterion, in a corresponding entry of the correlation prediction table.
