Abstract: 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.

Abstract: Disclosed are methods, systems and devices for varying operations of a transponder device based, at least in part, on an availability of energy and/or power that may be harvested and/or collected. In one particular implementation, operations to generate one or more signals from sensor circuitry and/or to perform computations may be varied based, at least in part, on an availability of harvestable and/or collectable energy and/or power.

Abstract: A method and apparatus for transferring data maps the data to a modulation code using an encoder circuit having a configuration. A binary symbol of the data is mapped to a modulation code having a plurality of modulation digits and a modulation signal is generated based on the modulation code. A transmitter drive signal is modulated based on the modulation signal. A configuration of the encoder circuit is set based on a determined performance level. The transmitter drive signal may be used to produce an electromagnetic field by generating a positive, negative or zero electrical current in an induction coil of a first semiconductor die. A current induced by the electromagnetic field in an induction coil of a second semiconductor die is demodulated to recover the data whereby the data is transferred from the first semiconductor die to the second semiconductor die.

Abstract: An apparatus and method are described for generating debug information. The apparatus has processing circuitry for executing a sequence of instructions that includes a plurality of debug information triggering instructions, and debug information generating circuitry for coupling to a debug port. On executing a given debug information triggering instruction, the processing circuitry is arranged to trigger the debug information generating circuitry to generate a debug information signal whose form is dependent on a control parameter specified by the given debug information triggering instruction. The generated debug information signal is output from the debug port for reference by a debugger. The control parameter is such that the form of the debug information signal enables the debugger to determine a state of the processing circuitry when the given debug information triggering instruction was executed.

Abstract: The present disclosure provides a method and apparatus for communicating between dice of an inductively-coupled 3D integrated circuit (3D-IC). A transmit resonant circuit at a transmit die is inductively coupled to a first receive resonant circuit at a first receive die, and to a second receive resonant circuit at a second receive die. The resonant circuit at the targeted receive die is tuned to the frequency of resonance of the transmit resonant circuit, while the resonant circuit at the untargeted receive die is detuned, resulting in lower power consumption for a given bit error rate at the targeted die.
