PROBLEM TO BE SOLVED: To solve the problem that a product cost increases when the required amount of a high-speed accessible memory necessary during performing timer processing increases.SOLUTION: An information processing device includes a first memory for storing high-order bits of a count to be used by a timer, a second memory for storing low-order bits of the count value to be accessible at a higher speed than the first memory, first calculation means for performing a first prescribed calculation of the low-order bits stored in the second memory at a predetermined cycle, and second calculation means for performing a second prescribed calculation of the high-order bits stored in the first memory when the low-order bits stored in the second memory become a prescribed value.SELECTED DRAWING: Figure 3 |
