PROBLEM TO BE SOLVED: To provide a calculation device suitable for an intermittent operation capable of achieving the suppression of useless power consumption in an operation by a large-scale memory and operation setting to prevent a start-up time in the case of shifting the power source of a memory from OFF to ON from affecting processing.SOLUTION: The calculation device includes: first storage means for storing a first instruction code; second storage means for storing a second instruction code; central arithmetic processing means for executing an instruction in accordance with the first instruction code stored in the first storage means and the second instruction code stored in the second storage means; and power supply control means for putting the first storage means and the second storage means in an on-state or an off-state in response to the instruction. The central arithmetic processing means executes an instruction to put the second storage means in an on-state or an off-state in response to the first instruction code, and to put the first storage means in an on-state or an off-state in response to the second instruction code. |
