Title: Controller and method
Inventor: JEREMY GREENWOOD
IPC: B60L15/20
Filed: 2017-03-20
Abstract: A controller 7 is used to control an electric machine 6 to drive a wheel 4 of a vehicle 1 (e.g. EV, HEV, PHEV, BEV). The controller includes a processor 15 that: determines an effective torque T; receives a wheel speed signal 10 indicative of the wheel speed S; and outputs a speed demand signal 27 for controlling the wheel speed. The processor detects changes in the effective torque as the wheel speed changes and modifies the speed demand signal in dependence on the detected changes in effective torque. The effective torque may be determined at the wheel, particularly when each wheel of the vehicle is driven by a separate motor. The processor may determine a derivative dT/dS of the effective torque with respect to the wheel speed. An inverter 5 controls the electric machine to force commutation at a constant speed. The current induced in the armature windings may be used to estimate the effective torque at the wheels. The inverter and/or the electric machine provide a feedback signal, comprising a commutation current signal and the phase angle of the electric machine, to a torque estimator which uses the commutation current and phase angle to estimate the effective torque at the wheel.

Title: An apparatus and method for speculatively vectorising program code
Inventor: PENG SUN
IPC: G06F9/38
Filed: 2019-07-01
Abstract: Apparatus for speculatively vectorising program code comprises processing circuitry for executing program code, the program code including an identified code region comprising a plurality of speculative vector memory access instructions. Execution of each speculative vector memory access instruction performs speculative vectorisation of a series of scalar memory access operations using a plurality of processing lanes. Tracking storage maintains, for each speculative vector memory access instruction, tracking information providing an indication of a memory address accessed within each lane. Checking circuitry references the tracking information during execution of the identified code region to detect any inter lane memory hazard resulting from the execution of the plurality of speculative vector memory access instructions. For at least a first type of inter lane memory hazard, a status storage element maintains an indication of each lane for which the checking circuitry has determined the presence of that type of memory hazard. Replay determination circuitry is arranged, when an end of the identified code region is reached, to be responsive to the status storage element identifying at least one lane as having an inter lane memory hazard, to trigger re-execution of the identified code region for each lane identified by the status storage element.

Title: Image rendering method and apparatus
Inventor: MARK JACOBUS BREUGELMANS
IPC: G06T11/40
Filed: 2019-11-26
Abstract: Conventional 3D displays represent objects as a mesh of polygons, typically triangles and to render an object on a screen of pixels the mesh must be converted to a corresponding set of pixels by a process known as rasterization. This application is concerned with foveated rendering wherein rasterization is performed on a per-pixel level for the part of an image expected to be the centre of a user’s view, the foveal region whilst performing rasterization on only a subset of pixels in the part of the image outside of the foveal region. The invention of this application is directed to such a foveated rendering method known as flexible scale rasterization(FSR) in which triangles of a mesh correspond to an array of “bins” which have a non-uniform spatial resolution, typically defined by two curves respectively specifying horizontal and vertical mappings between a uniform distribution and the FSR distribution. The invention claimed performs flexible scale rendering with a first bin distribution for a luminance channel and maps the results to a first pixel space then performs flexible scale rasterization with a second bin distribution for chrominance channels and maps the results to a second pixel space then outputs an image based upon the luminance and chrominance results mapped to the first and second pixel spaces wherein the second bin distribution includes larger bins than the first bin distribution in a region outside the locus of interest.
