Abstract: A processor and an operating method thereof are provided. The processor comprises a plurality of physical registers and a renaming circuit. The renaming circuit is coupled to the plurality of physical registers and is configured to receive an instruction sequence and check the instruction sequence. When a current instruction of the instruction sequence comprises a move instruction, the renaming circuit assigns a first physical register, which is assigned to a source logical register of the current instruction previously, to a destination logical register of the current instruction. The first physical register is one of the plurality of physical registers.

Abstract: An instruction translation circuit, a processor circuit, and an executing method thereof are provided. The instruction translation circuit is adapted for being disposed in the processor circuit. The instruction translation circuit includes a formatted instruction queue, a first instruction translator, an instruction detection circuit, and a second instruction translator. The formatted instruction queue stores a plurality of formatted macro instructions. The first instruction translator translates a first formatted macro instruction of the formatted macro instructions and outputs a first micro instruction. When the instruction detection circuit determines that a trap bit in the first formatted macro instruction is set and a part of the first formatted macro instruction can be translated in advance, the instruction detection circuit outputs first trap information.
