A method and apparatus generate computer executable code as one or more code portions, detect a number of processing operations required to reach one or more predetermined stages in execution of each code portion, and associate with each code portion one or more progress indicators, each representing a respective execution stage of the one or more predetermined stages within execution of that code portion. Further aspects include, when a current execution stage of the program code is at least at the execution stage represented by the progress indicator, a first operation may be performed, and when the current execution stage of the program code is before the execution stage represented by the progress indicator, a second operation different from the first operation is performed.

Method and apparatus for instruction checkpointing in a data processing device powered by an unpredictable power source

In response to a power-loss warning event occurring during data processing, a checkpointing process is performed to save a checkpoint of context data associated with the data processing to non-volatile data storage. In response to detection of a power recovery event occurring when the checkpointing process is still in progress, it is determined whether a checkpoint abort condition is satisfied, based at least on a checkpoint progress indication indicative of progress of the checkpointing process. If the checkpoint abort condition is unsatisfied, the checkpointing process can continue. If the checkpoint abort condition is satisfied, the checkpointing process is aborted to allow the data processing to resume.

Checkpointing

Smart labels, methods of operating smart labels, and associated contexts in which such smart labels may be used are disclosed. The smart label, for use in conjunction with consumer product packaging, comprises an energy harvester to capture ambient energy to provide a source of electrical energy and electronic circuitry powered by the electrical energy. A fuse provides an electrical connection between the energy harvester and the electronic circuitry and destruction of the fuse permanently disconnects the energy harvester from the electronic circuitry. Unnecessary continued operation of the electronic circuitry powered by the energy harvester can therefore be prevented, for example when the consumer product packaging is disposed of or recycled, which may be an undesirable heat source. Smart labelling, and a connected network of smart bins which can read the smart labelling, may also be used to promote consumer recycling of consumer product packaging.

Circuitry comprises driver circuitry to control display of a prevailing display image by display elements of a display device, the driver circuitry generating a signal providing electrical charge for storage by display elements, in which an electrical charge stored by a display element controls a display output of that display element; detector circuitry to detect, for a display image transition from a current display image to a second, display image, a first set of one or more display elements which are in a respective first state controlled by a first stored electrical charge in the current display image and which are required to be in a respective second state controlled by a second electrical charge, in the second display image; switching circuitry, responsive to the detector circuitry, to divert electrical charge from the set of display elements to secondary charge store in response to initiation of the display image transition.
