ALEXANDRIA, Va., Sept. 17 -- United States Patent no. 12,417,104, issued on Sept. 16, was assigned to Arm Ltd. (Cambridge, Great Britain).

"Switching a predicted branch type following a misprediction of a number of loop iterations" was invented by Guillaume Bolbenes (Vallauris, France), Thibaut Elie Lanois (Peymeinade, France) and Houdhaifa Bouzguarrou (Austin, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "When a predicted branch type for a given address is a first branch type corresponding to a predicated-loop instruction for triggering processing circuitry to perform a variable number of iterations of a predicated loop body, branch prediction circuitry generates a first type of branch prediction ind...
