PROBLEM TO BE SOLVED: To efficiently operate an arithmetic unit without any waste. SOLUTION: Plural instructions and information indicating a competing state for those plural instructions are stored in a cache 2301. A first mask circuit 2302 and a second mask circuit 2303 input the instructions and the information from the cache, and decides the instruction to be outputted according to this information. An arithmetic unit executes the decided instruction. Thus, the instruction is applied to the arithmetic unit based on the information outputted from the memory so that plural arithmetic units can be operated without any waste, and processing efficiency can be improved. |
