Broadly speaking, the present techniques provide methods, apparatus and systems for monitoring operation of a device. More particularly, the present techniques provide methods for monitoring operation of a device based on a device firmware update that is associated with at least one power profile.

Systems and methods for monitoring power consumption

There is described a method, data processing apparatus and computer program product for initializing storage protection, the storage protection for enforcing access permission for a region of storage configured in a layout of regions according to at least one security constraint, the method comprising: receiving a set of storage requirements; generating a layout whereby the layout comprises a combination of storage regions that accommodate the storage requirements within the at least one security constraint; and configuring the storage protection according to the generated layout, wherein generating a layout comprises: calculating, for each storage requirement, a list of all storage regions that could accommodate the storage requirement within the at least one security constraint; selecting and testing combinations of storage regions until a selected combination accommodates the storage requirements within the at least one security constraint; and providing the accommodated combination of storage regions as a region layout.

Optimized storage protection

Broadly speaking, the present techniques provide methods, apparatus and systems for monitoring operation of a device. More particularly, the present techniques provide methods for monitoring operation of a device by observing state transitions which occur during the running of a device process following a firmware update, and either comparing the observed state transitions to a state transition map generated within the device or comparing the observed state transitions to a state transition model in, or associated with, the firmware update.
