A compute node capable of enhanced performance and/or energy savings is proposed. The proposed compute node may check whether a last instruction of a first group—retrieved in a first decode cycle—is potentially a fusible instruction. If so, the proposed compute node may refrain from decoding the last instruction in the first decode cycle. Instead, the proposed compute node may determine if a first instruction of a second group of instructions retrieved in a second decode cycle (subsequent to the first decode cycle) is fusible with the last instruction of the first group. If so, the two instructions may be fused to a single micro-operation.
