The present invention facilitates utilization of flexible and efficient power savings in graphics systems. A graphics power management method loads a first set of graphics commands from a CPU into a GPU at the beginning of a frame cycle. The CPU is put into a power saving mode after the loading is complete. The GPU processes the commands and forwards the results to a graphics buffer. The display begins the presentation of the data at the beginning of the following refresh cycle. The CPU leaves the power savings mode at end of the frame cycle to begin loading a second set of commands. The CPU recognizes the end of the frame cycle by counting a predetermined number of frame flip interrupt requests. After the CPU counts the predetermined number of frame flip interrupt requests the CPU begins to communicate additional graphics commands and then returns to the power savings mode.

An image forming device having a communication unit includes a system control unit which controls the entire image forming apparatus, the system control unit having a CPU that is set in one of a normal mode, a power-saving mode and a sleep mode by controlling a power supply unit. A real-time clock keeps track of hours, minutes and seconds of a current time and outputs a signal indicating the current time. A register stores a return time that indicates a time the CPU is to be switched from one of the power-saving mode and the sleep mode to the normal mode. A comparator compares the current time of the clock with the return time of the register, and outputs, when a match occurs, a control signal to the CPU so that the CPU is switched to the normal mode.

The time-delay pulses control conduction period of a semi-conductor switching device for transmitting AC power to a lighting load. This lighting control system enables the lighting load performing two-level or multi-level illumination in a simple and power saving manner. While the conventional circuits use cumbersome passive resistor-capacitor scheme to generate required timing control, this lighting control system uses simple scheme based on a built-in oscillator in the microcontroller. This scheme provides high flexibility and accuracy to implement delay-time triggering. The system and method in the present invention may simultaneously be applicable to lighting loads of different impedance types, especially to incandescent lamp, fluorescent lamp, and AC light emitting diode.
