15 Mar 2013
TL;DR: In this article, an electronic device consisting of a receiver, a display, an application processor and a sensor hub is disclosed, where the receiver is configured to receive notifications from a remote device.
Abstract: There is disclosed an electronic device comprising a receiver, a display, an application processor and a sensor hub. The receiver is configured to receive notifications from a remote device. The display is configured to provide information including notifications. The application processor and the sensor hub are in communication with the display. The application processor is configured to provide instructions for displaying full screen information at the display during a non-sleep mode of the electronic device. The full screen information includes a first notification associated with information received by the electronic device during the non-sleep mode. The sensor hub is configured to provide instructions for displaying partial screen information at the display during a sleep mode of the electronic device. The partial screen information includes a second notification associated with information received by the electronic device during the sleep mode.

TL;DR: In this article, a run list is provided allowing a coprocessor to switch from one task to the next, without waiting for CPU intervention, and a "flip" technique is described that can switch a base reference for a display from one location to another.
Abstract: Techniques for minimizing coprocessor "starvation," and for effectively scheduling processing in a coprocessor for greater efficiency and power. A run list is provided allowing a coprocessor to switch from one task to the next, without waiting for CPU intervention. A method called "surface faulting" allows a coprocessor to fault at the beginning of a large task rather than somewhere in the middle of the task. DMA control instructions, namely a "fence," a "trap" and a "enable/disable context switching," can be inserted into a processing stream to cause a coprocessor to perform tasks that enhance coprocessor efficiency and power. These instructions can also be used to build high-level synchronization objects. Finally, a "flip" technique is described that can switch a base reference for a display from one location to another, thereby changing the entire display surface.

TL;DR: In this article, a microcontroller comprising a central processing unit and a further fault processing unit is proposed for automotive System On Chip (SoC) applications, which includes a method for designing and verifying such faultrobust system on chip, and a fault-injection technique based on e-language.
Abstract: A microcontroller comprising a central processing unit and a further fault processing unit suitable for performing validation of operations of said central processing unit. The further fault processing unit is external and different with respect to said central processing unit and said further fault processing unit comprises at least a module for performing validation of operations of said central processing unit and one or more modules suitable for performing validation of operations of other functional parts of said microcontroller. Validation of operations of said central processing unit is performed by using one or more of the following fault tolerance techniques: data shadowing; codef data processing legality check; addressing legality check; ALU concurrent integrity checking; concurrent mode/interrupt check. The proposed microcontroller is particularly suitable for application in System On Chip (SoC) and was developed by paying specific attention to the possible use in automotive System On Chip. The invention also includes a method for designing and verify such fault-robust system on chip, and a fault-injection technique based on e-language.

TL;DR: In this article, a networked sensor system that simultaneously acquires, processes, and transmits sensor data under the control of a central processing unit is described, which includes sensors connected to sensor processing modules.
Abstract: A networked sensor system that simultaneously acquires, processes, and transmits sensor data under the control of a central processing unit. The system includes sensors connected to sensor processing modules. The sensor processing modules are serially coupled together and to the central processing unit by a fiber optic network. The central processing unit can change the sensor sampling rate by changing a global clock rate, can describe the number and layout of sensor processing modules and their associated sensors allowing for reconfiguration in accordance with a desired application, and can download code to the sensor processing modules for modifying processing functions for a given application. The global clock also allows for synchronous sampling throughout the network. Sensor gain in the sensor processing modules is dynamically programmed by the central processing unit.
