Abstract

Techniques of power management in devices having multi-processor core are described herein. In an example, an ethernet controller of a device comprises a MAC layer module which receives a data packet through a physical network. A multi-processor core coupled to the ethernet controller comprises a first and a second processor. The first and second processor comprise a first driver and a second driver, respectively. The second driver determines that the first processor has entered a power saving mode, receives the data packets directed towards the multi-processor core from the MAC layer module and stores the data packet in a data structure. The econd driver invokes the first driver based on a determination that the data packet is to be handled by the first processor and provides an address of the data structure storing the data packet to the first driver, the data structure being accessible to the first driver.

Abstract

Object model data is obtained, representing one or more objects to be generated by an additive manufacturing system. An object model is generated, representing an arrangement of the one or more objects within a build volume, by determining a solution to a packing optimization function. A layer of the object model is analysed to determine a parameter representing the complexity of the layer, and if the determined parameter exceeds a given threshold, the process is repeated by generating a revised object model representing a different arrangement of the one or more objects within the build volume.

Abstract

BIOS for a computing device having internal and external PCIe devices includes an OpROM manager having a selectively enabled update feature. Upon boot-up of the computing device, the BIOS to copy to an execution database of the computing device an OpROM from each external PCIe device and an OpROM for each internal PCIe device from BIOS. With the update feature enabled, the OpROM manager provides for each PCIe device a latest version number of corresponding OpROM from versions stored in the execution database and an update database of the computing device to a remote OpROM monitor which maintains a database of a most recently certified OpROM for each PCIe device for the BIOS. For each PCIe device, if the most recently certified OpROM has a version number more recent than the latest OpROM version number, the OpROM manager copies the most recently certified OpROM to the update database.

Abstract

In one example, an electronic device may include a display screen defining a plurality of display regions. Further, the electronic device may include a camera to capture an image of an operator of the electronic device. Furthermore, the electronic device may include a controller operatively coupled to the camera and the display screen. The controller may detect an orientation of the operator's face with respect to the display screen using the captured image. Further, the controller may determine a first display region of the plurality of display regions corresponding to the detected orientation of the operators face. Furthermore, the controller may activate the first display region to position a cursor of a pointing device within the first display region.
