Title: Leakage current reduction in an integrated circuit
Inventor: IDGUNJI SACHIN SATISH
IPC: H03K19/00
Filed: 2013-11-14
Abstract: An integrated circuit (IC) 2 is provided with operational mode header transistors 10 which connect a virtual power rail 6 to a power supply VDD 16. A controller circuit 22 responds to a sensed voltage signal from a voltage sensor 24 which reads the virtual rail voltage VVDD and, in response, the sensed virtual rail voltage, generates a control signal which controls the operational mode transistors 10. The control signal is derived from an interface voltage power supply 20 that provides higher voltage VDDIO than the VDD power supply and thus is able to overdrive the operational mode transistors 10 via a gate bias voltage. This provides a higher negative or reverse overdrive voltage. This both controls and reduces the current leakage through the operational mode transistors 10. The amount of leakage through the operational mode transistors 10 is controlled in a closed loop feedback arrangement operating so as to maintain a predetermined target value or range for the virtual rail voltage. A comparator compares a reference signal with the sensed signal and controls an adaptive retention mode device 25 whose output drives the operational mode transistors 10 and is also connected to a smoothing capacitor Cext. The operational mode transistor may also be controlled to support dynamic voltage and frequency scaling DVFS whereby the voltage and/or clock frequency supplied to the functional circuitry is changed to support different performance levels. The speed of control of the operational mode transistors is sufficiently high to avoid changes in processing activities of the functional circuitry 4 moving the virtual rail voltage VVDD outside the target range. A static retention mode and a normal operational mode are also enabled by means of devices connected to ground 38 or to the VDD supply 36 respectively under the control of the controller.

Title: Interface and communication device
Inventor: KATO NOBORU
IPC: H01Q7/06
Filed: 2013-10-29
Abstract: An antenna (34) of a communication terminal is disposed on the lower surface side of a reflective plate (71) that constitutes a display (32). When the reflective plate (71) is illuminated by an LED light source (82), the antenna (34) becomes invisible from the display screen (surface on the +Z side) side of the display (32). Consequently, it becomes unnecessary to form an antenna coil (62) that constitutes the antenna (34) using a transparent electrode, and thus it becomes possible to form the antenna coil using various materials with high conductivity. Accordingly, the antenna (34) with high sensitivity can be manufactured at low cost, thereby enabling good short-distance communication with an external device (90) located on the display screen side of the display (32).

Title: Decoding method and corresponding device
Inventor: CHRISTOPHE GISQUET
IPC: H04N19/70
Filed: 2015-06-08
Abstract: Decoding a picture parameter set used for decoding images from a bitstream. In a first embodiment a colour component parameter which indicates whether the image is monochrome and is involved in at least two steps of the decoding method is decoded and at least one step of the decoding method is skipped or amended if the parameter indicates that the image is monochrome. Preferably, this step is skipped rather than amended and relates to the application of a residual adaptive colour transform. In a second embodiment the decoding method includes a step related to the residual adaptive colour transform and a step for defining a palette predictor initialiser. The defining step is processed based on the value of a colour component parameter which indicates whether or not the image is monochrome and the colour component parameter is inferred from the execution of the residual adaptive colour transform. These embodiments rely on a redundancy in the parameters encoded in the extension to the picture parameter set defined in the HEVC Screen Content Coding draft specification A third embodiment has a step of initialising a palette predictor, the step being governed by rules when switching between images based on the number of colour components in each image.
