Patent number: 12131155Abstract: An apparatus and method are provided for speculatively vectorising program code. The apparatus includes processing circuitry for executing program code, the program code including an identified code region comprising at least a plurality of speculative vector memory access instructions. Execution of each speculative vector memory access instruction is employed to perform speculative vectorisation of a series of scalar memory access operations using a plurality of lanes of processing. Tracking storage is used to maintain, for each speculative vector memory access instruction, tracking information providing an indication of a memory address being accessed within each lane. Checking circuitry then references the tracking information during execution of the identified code region by the processing circuitry, in order to detect any inter lane memory hazard resulting from the execution of the plurality of speculative vector memory access instructions.Type: GrantFiled: March 25, 2020Date of Patent: October 29, 2024Assignees: Arm Limited, The Chancellor, Masters and Scholars of the University of CambridgeInventors: Peng Sun, Timothy Martin Jones, Giacomo Gabrielli

Patent number: 11874459Abstract: The disclosure provides a display device for head mounting, in particular a Maxwellian display device, with an enlarged eye-box. The display device includes a light source emitting light beams for forming an image, an optical system for guiding the light beams to a beam forming element. The beam forming element is configured to converge each of multiple sets of the light beams into a different point of convergence, for example on an exit pupil of the display device. Each point of convergence is a convergent viewing point for a user. The eye-box is thus enlarged.Type: GrantFiled: September 24, 2020Date of Patent: January 16, 2024Assignees: Huawei Technologies Co., Ltd., The Chancellor, Masters and Scholars of The University of CambridgeInventors: Tao Lin, Qing Zhang, Jia Jia, Pawan Shrestha, Matt Pryn, Daping Chu

Patent number: 10730862Abstract: The present invention relates to bifunctional compounds, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins that are degraded and/or otherwise inhibited by bifunctional compounds of the present invention. In particular, the present invention is directed to compounds, which contain on one end a VHL ligand that binds to the ubiquitin ligase and on the other end a moiety that binds a target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. The present invention exhibits a broad range of pharmacological activities associated with compounds of the present invention, consistent with the degradation/inhibition of targeted polypeptides.Type: GrantFiled: January 11, 2013Date of Patent: August 4, 2020Assignees: Yale University, Glaxosmithkline Intellectual Property Development, Cambridge Enterprise Limited University of CambridgeInventors: Craig M.
