摘要： A handheld device 300 generates a verification image to indicate that the device is operating in a secure domain. The verification image is generated in dependence upon secure data stored within a secure region 324 of a memory 310 and user input data captured from a user input device 314, 316, 320. The secure data may be data defining a three-dimensional object. The user image data may be captured from accelerometers 314 defining a viewpoint of the secret three-dimensional object.

摘要： A data processing apparatus and method are provided for controlling access to registers. The data processing apparatus comprises a processing unit for performing data processing operations on data values, the processing unit having a plurality of modes of operation. A plurality of registers are provided for storing data values for access by the processing unit, with a subset of those registers being mode specific registers. Each mode specific register is used by the processing unit when operating in an associated mode of operation. The processing unit is switchable between a plurality of contexts, the data values stored in the plurality of registers being dependent on a current context of the processing unit. The processing unit performs a switch operation to switch from the current context to a new context, during which the data values in the registers are updated having regard to the new context. A control register is provided which, for at least one mode of operation having at least one mode specific register associated therewith, has an access field which is programmable by the processing unit when operating in a predetermined mode of operation. When the access field is set, the processing unit is selectively denied access to the associated at least one mode specific register, whereby updating of the data values in the associated at least one mode specific register is avoided during the switch operation. This significantly increases the speed of the switch operation.

摘要： Power management control software including power management policies is provided with those policies divided into observation code 18, 20, 22 and response code 26, 28, 30. When predetermined execution points 10, 12 within the operating system 2 are reached registered observation code 18, 20 for those execution points 10, 12 is triggered to be executed and serves to store event data within an event data store 24. At another time independent of the execution points 10, 12, the response code 26, 28, 30 is executed to read the event data from the event data store 24 and generate power control predictions and control signals therefrom.
