Abstract: A data processing system operates in a plurality of modes including a first privilege mode and a second privilege mode with the first privilege mode giving rights of access that are not available in the second privilege mode. Application code executes in the second privilege mode and generates function calls to hypervisor code which executes in the first privilege mode. These function calls are to perform a secure function requiring the rights of access which are only available in the first privilege mode. Scheduling code which executes in the second privilege mode controls scheduling of both the application code and the hypervisor code. Memory protection circuitry operating with physical addresses serves to control access permissions required to access different regions within the memory address space using configuration data which is written by the hypervisor code. The hypervisor code temporarily grants access to different regions within the physical memory address space to the system in the second privilege mode as needed to support the execution of code scheduled by the scheduling code.

Abstract: A method for detecting and responding to a configuration setting capable of causing undesired energy consumption in a configurable electronic device comprises measuring a power state of at least one connection point of the configurable electronic device to establish a measured power state value; comparing the measured power state value with a stored power state value for the connection point; and responsive to a discrepancy between the measured power state value and the stored power state value for the connection point where the discrepancy is capable of causing undesired energy consumption, emitting a condition signal.

Abstract: A data processing apparatus has a scheduler which maintains a queue of function calls to be scheduled for processing by processing circuitry. The scheduler identifies, for every function call in the queue, a target time window within which the processing circuitry should process the function call. The scheduler schedules processing of the function calls based on the target time window.

Abstract: A data processing device 2 has a processor 4 which executes software directly from non-volatile memory 6, 8. The processor 4 has a runtime component 20 which dynamically maps software element identifiers specified by the software to corresponding software elements in memory 6, 8. Mapping information 22 is used to determine which software elements identifiers correspond to which software elements. This provides a level of indirection which can be used to make software updates more efficient, by updating only parts of the software while leaving old parts of the software as they are. Updated software elements can be stored to memory and the mapping information updated to point to the new elements, while existing mappings may be retained.
Abstract translation: 数据处理设备2具有直接从非易失性存储器6,8执行软件的处理器4.处理器4具有运行时组件20，其将由软件指定的软件元素标识符动态地映射到存储器6,8中的相应软件元件。 映射信息22用于确定哪些软件元素标识符对应于哪些软件元素。 这提供了一定程度的间接，可以通过只更新软件的一部分，同时保留软件的旧部分，从而使软件更新更加高效。 更新的软件元素可以存储到内存中，映射信息更新为指向新的元素，而现有的映射可能被保留。

Abstract: Proximity of a wearable processing device to a data processing apparatus is detected based on wireless signals received by the data processing apparatus from the wearable processing device. A user input operation is detected which comprises a physical interaction with the data processing apparatus. In response to detecting the user input operation, at least one detection parameter is calibrated for the proximity detection. This provides a convenient technique for calibrating the proximity detection which does not require complicated operations from the user.
