Arm officially released Komeda, a new display solution, at a technology forum held in Taipei in early November to meet the needs of the next generation of mobile devices in virtual reality (VR), high dynamic range (HDR), multi-window / multi-display and multi- Panel and interface technologies and other challenges, claiming to be by providing intelligent solutions to enhance display performance.
Focusing on the growing demand for end-user displays of all types of devices, Arm set up its IP product line in 2013 and acquired Assertive Display technology in 2016 through the acquisition of Apical, a visual IP / embedded PC supplier ; While the recently released Komeda display architecture includes Mali-D71 display processor IP, CoreLink MMU-600 memory management unit IP, and Assertive Display 5 (AD5) display management core, which enables high-end imaging of the device's main processor and GPU Display functions bring computing tasks, while enhancing the user experience without sacrificing system performance.
Ian Hutchinson, Director of Marketing for Arm Computing Group, said that in an effort to enhance the visual experience of mobile device users, mobile displays are moving toward higher resolutions and support for higher-order functions: for example, the screen needs VR headsets near both eyes to progress To 2,560 × 1,440 pixels, also achieve 120fps higher picture update rate (frame rate) to reduce the delay, to avoid image blur; also can enhance the fidelity of the image to provide higher saturation and brightness display HDR function, and to allow the implementation of separate Multiple task windows present multiple window modes simultaneously on the phone screen; these pose significant challenges to the mobile device's display system design and power consumption.
Komeda shows that the architecture-integrated three IPs are designed to help mobile device monitors meet the above design challenges. The latest generation of display processors, the Mali-D71, is designed for VR applications with high resolution of 4K and above, which transmits the image output signal to the front of the screen In the final phase, GPU workload was shared by overlays, rotations, high-quality scaling, and other image-processing methods, with side-by-side operating mode claims of 30% lower system power consumption; CoreLink MMU-600 was affordable Display signal processing data management tasks to reduce the latency of 50%; and AD5 display management core in any dynamic range and color gamut of the screen rendering HDR content, in addition to improving the performance of the display in outdoor light through the ambient light Compensation, even dark scenes also allow users to see more details of the image.
