20160139655 | Energy Efficiency Strategy for Interrupt Handling in a Multi-Cluster System - Energy efficiency is managed in a multi-cluster system. The system detects an event in which a current operating frequency of an active cluster enters or crosses any of one or more predetermined frequency spots of the active cluster, wherein the active cluster includes one or more first processor cores. When the event is detected, the system performs the following steps: (1) identifying a target cluster including one or more second processor cores, wherein the each first processor core in the first cluster and each second processor core in the second cluster have different energy efficiency characteristics; (2) activating at least one second processor core in the second cluster; (3) determining whether to migrate one or more interrupt requests from the first cluster to the second cluster; and (4) determining whether to deactivate at least one first processor core of the active cluster based on a performance and power requirement. | 05-19-2016 |
20160139964 | Energy Efficient Multi-Cluster System and Its Operations - A multi-cluster system having processor cores of different energy efficiency characteristics is configured to operate with high efficiency such that performance and power requirements can be satisfied. The system includes multiple processor cores in a hierarchy of groups. The hierarchy of groups includes: multiple level-1 groups, each level-1 group including one or more of processor cores having identical energy efficiency characteristics, and each level-1 group configured to be assigned tasks by a level-1 scheduler; one or more level-2 groups, each level-2 group including respective level-1 groups, the processor cores in different level-1 groups of the same level-2 group having different energy efficiency characteristics, and each level-2 group configured to be assigned tasks by a respective level-2 scheduler; and a level-3 group including the one or more level-2 groups and configured to be assigned tasks by a level-3 scheduler. | 05-19-2016 |

20110227819 | INTERACTIVE THREE-DIMENSIONAL DISPLAY SYSTEM AND METHOD OF CALCULATING DISTANCE - An interactive three-dimensional display system includes a three-dimensional display panel which has an optical sensor array, an interactive device which includes a projection light source and a shadow mask, and an image recognizing unit. The shadow mask has a pattern to define an image projected by the interactive device. The image is captured by the optical sensor array. The pattern includes two strip patterns which cross each other. The image includes two strip images which cross each other. The image recognizing unit is electrically connected with the optical sensor array and calculates relative positions of the interactive device and the three-dimensional display panel according to the image. A method of calculating the relative positions includes calculating according to the lengths of one of the strip patterns and one of the strip images, and a divergent angle and tilt angle of the projection light source. | 09-22-2011 |
