Title: Method of controlling a vehicle
Inventor: ASHISH NAIDU
IPC: F02D41/00
Filed: 2016-03-07
Abstract: A method of controlling a vehicle having a drive train that comprises a variable displacement engine (10, fig 4) having a crankshaft connected to drive wheels (16) via a transmission (14) and an auxiliary machine, e.g. electric motor/generator (18). The motor (18) is connected directly to an engine crankshaft and to an energy storage device, e.g. a battery (20). An engine is switched from a cylinder disablement VDE mode to a normal mode when a torque demand and engine speed lie outside an outer range defined by a first threshold Tout and is switched from the normal mode to the VDE mode when the torque demand and engine speed lie within an inner range, lying within the outer range and defined by a second threshold TH. When operating within a torque demand and engine speed band between the two thresholds, the motor (18) draws energy from the battery (20) and supplements the output torque from the engine if operating in VDE mode and derives torque from the engine crankshaft to recharge the battery (20) if the engine is operating in the normal mode.

Title: A data processing apparatus and method for performing segmented operations
Inventor: MBOU EYOLE-MONONO
IPC: G06F9/38
Filed: 2015-01-21
Abstract: A data processing apparatus and method are provided for performing segmented operations. The data processing apparatus comprises a vector register store for storing vector operands, and vector processing circuitry providing N lanes of parallel processing, and arranged to perform a segmented operation on up to N data elements provided by a specified vector operand, each data element being allocated to one of the N lanes. The up to N data elements forms a plurality of segments, and performance of the segmented operation comprises performing a separate operation on the data elements of each segment, the separate operation involving interaction between the lanes containing the data elements of the associated segment. Predicate generation circuitry is responsive to a compute descriptor instruction specifying an input vector operand comprising a plurality of segment descriptors, to generate per lane predicate information used by the vector processing circuitry when performing the segmented operation to maintain a boundary between each of the plurality of segments. As a result, interaction between lanes containing data elements from different segments is prevented. This allows very effective utilisation of the lanes of parallel processing within the vector processing circuitry to be achieved.

Title: Non-volatile memory with adjustable cell bit shape
Inventor: LUIZ M FRANCA-NETO
IPC: H01L45/00
Filed: 2016-06-24
Abstract: Non-volatile resistive random access memory (RRAM, ReRAM) comprising adjustable cell bit shapes. The memory cell includes a gate electrode, a gate (oxide) insulator, a channel and one or more recording layers comprised preferably of phase change material. The channel layer supports a depletion region disposed between the gate electrode and the recording layer(s). Upon activating the gate, the channel layer may be depleted and current initially flowing through the channel will steer (divert, direct) through the recording layer. A portion of the recording (memory or storage) layer may be transformed from a first resistance to a second resistance state based on the current steered through the recording layer, whilst the size or shape (volume) of the transformed portion can be controlled to store one or more bits (Single or multi bit cell SLC, MLC). The geometry, size and shape and also the resistance of the recording layer may be determined by applying a constant or varying voltage to the gate and a constant or varying current to the channel layer. The recording (Phase Change) layer preferably supports the depletion region, the resistance dependent on the depth of the depletion region in the recording layer. A method of operation is also included. Alternative embodiments relate to a system comprising a plurality of the described memory cells and a processor to address each of the cells and apply current to the channel layer and apply a voltage to the gate of the cells. Figures 4A-5C demonstrate the effect of the variation in gate and channel voltages on the shape of the bit cell. Each memory cell may be integrated into a string of memory cells (figures 6-7) comprising of common shared series connected channel and recording layers,
