LOW-POWER GPU STATES FOR REDUCING POWER CONSUMPTION |
| 摘要 |
The disclosed embodiments provide a system that drives a display from a computer system. During operation, the system detects an idle state in a first graphics-processing unit (GPU) used to drive the display. During the idle state, the system switches from using the first GPU to using a second GPU to drive the display and places the first GPU into a low-power state, wherein the low-power state reduces a power consumption of the computer system. |

1. A method for driving a display in a computer, comprising:
driving the display with a first graphics-processing unit (GPU); switching from using the first GPU to drive the display to using a second GPU to drive the display; and transitioning the first GPU into a low-power state, wherein transitioning the first GPU into the low-power state comprises powering off the first GPU and an interface with the first GPU, and maintaining power to a video memory of the first GPU. |
