Abstract

Apparatuses and methods for branch prediction are provided. Branch prediction circuitry generates prediction with respect to branch instructions of whether those branches will be taken or not-taken. Hypervector generation circuitry assigns an arbitrary hypervector in deterministic dependence on an address of each branch instruction, wherein the hypervectors comprises at least 500 bits. Upon the resolution of a branch a corresponding hypervector is added to a stored taken hypervector or a stored not-taken hypervector in dependence on the resolution of the branch. The branch prediction circuitry generates a prediction for a branch instructions in dependence on a mathematical distance metric of a hypervector generated for that branch instruction from the stored taken hypervector or the not-taken hypervector.
