GPU graphics processor tends to mid-price high energy

Smooth touch screen experience, well-designed UI interface, realistic game and visual effects bring a brand new experience for multimedia applications with powerful CPU and GPU processing capabilities. The bright spots of multimedia applications in the future will be in mobile phones, tablet computers and other mobile platforms that integrate sensing technology, the Internet of Things, and home networking. Mobile terminals with high-end features and mid-range prices will be the mainstream of multimedia applications in the future.

In the recent "ARM Visual Experience and Graphics Technology Seminar" held in Shenzhen, Ian Ferguson, vice president of marketing for ARM's segment, told reporters that based on the above application trends, our new IP portfolio includes ARM® Cortex®- A12 processor and MaliTM-T622 graphics processor, and joined the latest video IP solution Mali-V500. Supported by ARM POPTM technology and DS-5TM tool suite, starting from the power consumption, performance and chip size, targeting the mid-priced mainstream mobile terminal market, consumers can enjoy virtualized, big.LITTLE processor technology at a medium price point. And various high-end functions such as GPU computing.

Based on the leading position of the ARM Cortex series in the mobile market, graphics processor cores represented by the ARM Mali series have also made great strides in the market in recent years. Truna Watt, director of channel marketing from ARM MPD in the United Kingdom, analyzed the reporter at the exchange. Currently, there are more than 20% of Android smart phones, over 50% of Android tablet PCs, and more than 70% of digital TVs with graphics cores are equipped with Mali GPUs. ARM Mali GPU licensing products have grown by 30% to 75. Data from ARM partners show that Mali GPU shipments have grown from less than 50 million SoCs in 2011 to 150 million in 2012. All these have promoted ARM's deep development in the visual experience and graphics technology market. Currently, the Cortex®-A9 processor and Mali-400 GPU have been widely used in DTV and STB. Samsung’s smart TV and the world’s first quad-core are built in by using a quad-core ARM Cortex-A15 processor and a Mali-T604 GPU. The processor F8000 series, with its innovative user interface and faster performance, has created a new way to enjoy TV content.

Mali GPU has achieved such rapid development in the past two years. One of the key factors is that ARM has been committed to creating a multi-win-win, innovation-growth ecosystem. Ian Ferguson analyzed that we interact with games, user interfaces and browsers, and browsers. Collaboration with partners in the fields of image and multimedia processing, augmented reality, graphic computing, and developer communities has continued to deepen cooperation. This not only ensures that the Mali processor's performance and features are fully utilized and utilized, but also through the industry chain. Downstream cooperation has promoted the innovation and growth of the entire ecosystem. In this exchange meeting, many ARM partners will use Mali processor products to conduct live demonstrations, allowing reporters to experience the GPU's superior computing capabilities for image and multimedia processing. It will give the future embedded industry With profound influence, many applications with high data density and high computational complexity, such as extended reality, face recognition and detection, will be fully presented in smart mobile and home entertainment devices with the help of graphic computing.

Our compiler tools can automate the migration of code on heterogeneous processor architectures and achieve maximum performance. Dr. Zhanghua Zhang of U.S. Multicore Technology Co., Ltd. introduced the video transcoding program implemented on ARM Mali GPU using multi-core heterogeneous technology. , Including shakehe and upscaling filters, using Mali-T600 series GPUs for calculations can not only accelerate performance but also achieve significant energy savings.

In recent years, under the trend of GPGPU heterogeneous computing, the accelerated application of multimedia through the graphics core has become more and more mature. Such as EyeSight's gesture recognition technology based on heterogeneous computing, high-quality images captured by the lens, noise reduction through heterogeneous operations, and then highly efficient identification, under normal circumstances can be 0.5 seconds The real-time and accurate recognition is achieved, and the TV picture can be operated with a simple gesture. In addition, if multi-face recognition is performed, the heterogeneous operation is not only more accurate, but also the judgment error is less.

Although the use of hardware video encoding and decoding is a trend nowadays, it cannot be supported in real time in the face of new standards such as HEVC (H.265). However, if the CPU architecture is used for soft solution and the current mobile phone is overloaded, it can be used at this time. Parallel computing approach to soft solution as an alternative, Lttiam Asian regional market general manager Guo Fangxu uses Exynos 5 Duo development platform for CPU and heterogeneous computing soft solution display, although power consumption is not as hard solution, but in addition to providing real-time decoding It also offers lower power consumption than pure CPU decoding.

It is understood that the HD resolution of HEVC decoding will greatly load the CPU. Therefore, a GPU-accelerated solution will be able to share part of the CPU system tasks. The GPU-accelerated solution will also enable HEVC to broadcast to 1080@60fps or 4kx2k @30 fps, and the GPU on the dual-core A15 will run to 30%. The cost of a dedicated hardware HEVC decoding SoC is eliminated. This also means that when you use H.265 with pure CPU decoding, the device will be very stuck. Now you can use the CPU and heterogeneous computing software to solve the problem. Your device can not only chat with Weibo, but also send messages, check emails, and watch smoothly. A H.265 video.

The ultimate sensory experience is the goal of the mobile and home entertainment equipment manufacturers competing to chase, and is also the key to the success of their products. The GPU graphics processor undoubtedly played an indispensable role. Through this conference, we experienced the endless fun of the GPU graphics processor for the users and saw the future of the GPU.
