Patent number: 11971743Abstract: A deformable electronic device includes a flexible display, one or more sensors, at least one imager, and one or more processors. The one or more sensors detect deformation of the deformable electronic device. The at least one imager, which is disposed beneath the flexible display, captures one or more images of an identifiable marker of the flexible display in response to the one or more sensors detecting the deformation of the deformable electronic device. The one or more processors estimate an amount of the deformation of the deformable electronic device as a function of how far the identifiable marker of the flexible display translates across the at least one imager during the deformation of the deformable electronic device.Type: GrantFiled: December 8, 2021Date of Patent: April 30, 2024Assignee: Motorola Mobility LLCInventors: Vivek K Tyagi, Chao Ma, Joseph V Nasti, Kevin Dao, Nikhil Ambha Madhusudhana

Patent number: 11960727Abstract: A system and corresponding method perform large memory transaction (LMT) stores. The system comprises a processor associated with a data-processing width and a processor accelerator. The processor accelerator performs a LMT store of a data set to a coprocessor in response to an instruction from the processor targeting the coprocessor. The data set corresponds to the instruction. The LMT store includes storing data from the data set, atomically, to the coprocessor based on a LMT line (LMTLINE). The LMTLINE is wider than the data-processing width. The processor accelerator sends, to the processor, a response to the instruction. The response is based on completion of the LMT store of the data set in its entirety. The processor accelerator enables the processor to perform useful work in parallel with the LMT store, thereby improving processing performance of the processor.Type: GrantFiled: September 30, 2022Date of Patent: April 16, 2024Assignee: Marvell Asia Pte LtdInventors: Aadeetya Shreedhar, Jason D.
