Abstract
To perform execution scheduling of function blocks so as to control the total required power of the function blocks within a supplyable power budget value, and thereby realize stable operations at low power consumption. Function block identifiers are allotted to all the function blocks, and to a RAM area that a power consumption control device can read and write, a list to store identifiers and task priority, power mode value showing power states, and power mode time showing the holding time of power states can be linked. A single or plural link lists for controlling the schedules of tasks operating on the function blocks, a link list for controlling the function block in execution currently in high power mode, a link list for controlling the function block in stop currently in stop mode, and a link list for controlling the function block in execution currently in low power mode are allotted, and thereby the power source and the operation clock are controlled by the power consumption control device.
