A computer vision processor in an image cluster defines a fenced memory region (FMR) that controls access to image data stored in a first portion of a trusted memory region (TMR). The computer vision processor receives FMR requests from an application implemented in a processing cluster. The FMR requests are to access the image data in the first portion of the TMR. The computer vision processor selectively allows the requesting application to access the image data. In some cases, the computer vision processor acquires the image data and stores the image data in the first portion of the TMR, such as buffers in the TMR. A data fabric selectively permits the image processing application to access the data stored in the TMR based on whether the image cluster has opened or closed the FMR for the portion of the TMR.

Secure computer vision processing

Systems, apparatuses, and methods for implementing a unified kernel virtual address space for heterogeneous computing are disclosed. A system includes at least a first subsystem running a first kernel, an input/output memory management unit (IOMMU), and a second subsystem running a second kernel. In order to share a memory buffer between the two subsystems, the first subsystem allocates a block of memory in part of the system memory controlled by the first subsystem. A first mapping is created from a first logical address of the kernel address space of the first subsystem to the block of memory. Then, the IOMMU creates a second mapping to map the physical address of that block of memory from a second logical address of the kernel address space of the second subsystem. These mappings allow the first and second subsystems to share buffer pointers which reference the block of memory.

Unified kernel virtual address space for heterogeneous computing

Systems, apparatuses, and methods for performing real-time video rendering with performance guaranteed power management are disclosed. A system includes at least a software driver, a power management unit, and a plurality of processing elements for performing rendering tasks. The system receives inputs which correspond to rendering tasks which need to be performed. The software driver monitors the inputs that are received and the number of rendering tasks to which they correspond. The software driver also monitors the amount of time remaining until the next video synchronization signal. The software driver determines which performance setting will minimize power consumption while still allowing enough time to finish the rendering tasks for the current frame before the next video synchronization signal. Then, the software driver causes the power management unit to provide this performance setting to the plurality of processing elements as they perform the rendering tasks for the current frame.

Real-time GPU rendering with performance guaranteed power management

A hybrid co-processing system including both complex instruction set computer (CISC) architecture-based processing clusters and reduced instruction set computer (RISC) architecture-based processing clusters includes a parser to derive from a hardware configuration specific to the CISC architecture, such as an ACPI table, a device tree specific to the RISC architecture for booting. The hardware configuration information indicated by the device tree is specific to the RISC architecture, and in different cases includes more, less, or revised information than a corresponding ACPI table for the same hybrid co-processing system.

In an aspect, a user equipment (UE) is positioned within a driver operation zone of a vehicle, one or more UE-based user interfaces (UIs) are restricted and forwarded to a vehicle-based UI controller to permit access to the one or more UE-based features via a vehicle-based UI. In another aspect, the UE in the driver operation zone is engaged in hands-free speakerphone mode via a vehicle audio system of the vehicle, and an attempt to transition the UE to handset-based audio mode is blocked. In another aspect, when a handset-based audio capture and/or playback attempt of the UE is detected, the UE interacts with a vehicle audio system to temporarily reduce volume being output by one or more proximal speakers. In another aspect, the UE streams media to a media presentation device in its own zone or another zone of the vehicle for presentation thereon.

This disclosure describes methods, techniques, devices, and apparatuses for graphics and display processing for light field projection displays. In some examples, this disclosure describes a projection display system capable of rendering and displaying multiple annotations at the same time. An annotation is any information (e.g., texts, signs, directions, logos, phone numbers, etc.) that may be displayed. In one example, this disclosure proposes techniques for rendering and displaying multiple annotations at the same time at multiple different focal lengths.

Accelerated light field display

A software application executing on at least one processor may output a video at a frame rate for display at a display device. The at least one processor may synchronize a refresh rate of the display device displaying the video to the frame rate of the video. In response to detecting a potential delay in displaying, at the display device, a frame of the video to be output by the software application, the at least one processor may time-shift at least one of: compositing of the frame and refreshing of the display device to mitigate the potential delay in displaying, at the display device, the frame of the video to be output by the software application.

Refresh rate matching with predictive time-shift compensation

The apparatus and method for displaying video data are disclosed. Reference refresh frequency and/or time may be predetermined or derived from predetermined values. Measured refresh frequency and/or time of display panels may be determined and compared against the reference refresh frequency and/or time. Based on the comparisons and through one or more control loops, display properties of the display panels may be adjusted so that one or more display panels may be in sync with respect to their refresh timings without dedicated hardware or a common hardwired synchronization signal.

Apparatus and method for synchronous display of video data

A method and apparatus for wireless communication may provide an RLC reset procedure tailored for a multipoint HSDPA system utilizing a plurality of disparate Node Bs to provide an RLC flow from an RNC to a UE. Some aspects of the disclosure provide for a flush request to be provided to each of a plurality of Node Bs utilized as serving cells in the multipoint HSDPA system, so that stale packets are not retained in internal buffers at the Node Bs following the RLC reset procedure. In some examples, the RLC reset procedure is only completed after confirmation that the flush of the internal buffers has been completed. Confirmation may be explicitly provided by each Node B utilizing a backhaul interface, or may be implicitly determined utilizing timers or signaling between the respective Node Bs.
