" Linglong " D8/D6/D2 DPU

Ultra-high-definition image display " core " engine

With the continuous advancement of terminal intelligent transformation, the application boundaries of video image display technology are constantly expanding, and technical trends such as ultra-high definition, ultra-large screen, cross-screen linkage, and multi-screen display are becoming more and more obvious. Various application scenarios have put forward higher requirements for key capabilities such as real-time processing, image quality enhancement, and data security of display technology. As the first display processor independently developed by ARM Technology, the "Linglong" D8/D6/D2 DPU can provide ultra-high-quality display experience for smart terminals such as car cockpits, mobile phones, PCs, tablets, TVs, and wearable devices with its advantages of flexible expansion, high efficiency and low latency, low system bandwidth, and high data security.

The Linglong D8/D6/D2 DPU is designed based on a multi-core architecture, supporting flexible programming and configuration on demand. The single-core performance can reach up to 8K60 frames per second, or can simultaneously process 4 channels of 4K60 frames per second real-time display output, and can support up to 16 layers of content input, effectively promoting the utilization and management of system resources. Thanks to the deep collaboration with the Arm ^® architecture, the Linglong D8/D6/D2 DPU integrates the Arm frame buffer compression (AFBC) technology to maximize bandwidth and power consumption while ensuring the high performance and high image quality of the overall system solution. The translation buffer unit (TBU) module in its built-in Arm system memory management unit MMU-600/700 can be specially optimized for different display scenarios to further reduce system access latency. In addition, the Linglong D8/D6/D2 DPU also supports the Arm TrustZone ^® media protection (TZMP) architecture, realizing a hardware-software integrated design, which can provide strong protection for the security of display data.

Overview of Linglong D8/D6/D2 DPU

Compared with the previous generation Arm Mali™-D71/D51/D37 DPU, the new "Linglong" D8/D6/D2 DPU has achieved a two-fold improvement in core performance. Specifically, its single-core performance has been increased from the original maximum supported 4K120 frames per second to 8K60 frames per second, and the real-time display output supported has been expanded from 2 to 4 channels, fully meeting the diversified display needs of smart application scenarios.

" Linglong " V510/V710 VPU

Next-generation ultra-high-definition video processing core

In order to cope with the challenges of mass information transmission and storage brought about by the popularization of high-definition video technology, the industry's latest international video coding standard H.266 can improve the compression efficiency of 4K and 8K ultra-high-definition videos. With the same image quality, H.266 can save about 50% of traffic compared with the previous generation standard, and the transmission and storage costs of high-definition videos can be significantly reduced.

As the first batch of encoding and decoding video processors in China that support the H.266 standard, the Linglong V510/V710 VPU adopts a programmable processing architecture that integrates multi-core and multi-format encoding and decoding. The encoding or decoding performance of a single core can reach 4K60 frames per second. According to the needs of different scenarios such as end, edge, and cloud, it provides 1-4 cores, 4-8 cores and other configurations. While greatly saving storage space and bandwidth costs, the Linglong V510/V710 VPU can also be easily configured on demand to ensure the best balance between system performance, power consumption and area.

Overview of Linglong V510/V710 VPU

Compared with the previous generation "Linglong" V6/V8 VPU, the new generation "Linglong" V510/V710 VPU has doubled the encoding and decoding performance, and the encoding quality in 4K/8K application scenarios can be improved by more than 25%. In particular, the screen display menu OSD pre-processing function has been added to better take into account the real-time encoding and decoding needs of mainstream markets and emerging applications. In addition, in order to help developers quickly deploy based on various video encoding and decoding standards, the "Linglong" V510/V710 VPU also provides a complete set of firmware tools and software support. With the architectural design of software and hardware interaction, developers can also flexibly expand and optimize existing hardware through software upgrades in the future.

After three years of iteration and optimization, the "Linglong" VPU has been authorized to more than 30 domestic partners and is widely used in many video application scenarios such as mobile terminals, PCs, smart cars, and smart security. In the future, Arm Technology's "Linglong" product line will continue to strengthen its multimedia technology stack, while integrating advanced AI processing units, striving to play a higher-level intelligent imaging "core" role in AI mobile phones, AI PCs, smart cars, data centers and other fields.
