Abstract: Systems and methods pertain to a branch target instruction cache (BTIC) of a processor. The BTIC is configured to store one or more branch target instructions at branch target addresses of branch instructions executable by the processor. At least one of the branch target instructions stored in the BTIC is a conditional branch instruction. Branch prediction techniques for predicting the direction of the conditional branch instruction allow one or more instructions following the conditional branch instruction, as well as a branch target address of the conditional branch instruction to also be stored in the BTIC.

Abstract: Providing loop-invariant value prediction using a predicted values table, and related apparatuses, methods, and computer-readable media are disclosed. In one aspect, an apparatus comprising an instruction processing circuit is provided. The instruction processing circuit is configured to detect a loop body in an instruction stream, and to detect a value-generating instruction within the loop body. The instruction processing circuit determines whether an attribute of the value-generating instruction matches an entry of a predicted values table. If the attribute of the value-generating instruction is determined to be present in the entry of the predicted values table, the instruction processing circuit further determines whether a counter of the entry exceeds an iteration threshold.
