Clear Human-Computer Interaction barriers around computing

With one eye and one gesture, you can control all the smart terminal devices to achieve accessibility to human-computer interaction. AMD's computation will turn this dream into reality and redefine the future of computation.

In a 360-degree dome theater, a group of animated monsters are playing various types of musical instruments, and you can use gestures to control the actions of these monsters. This is not a fantasy, but amd uses advanced surround technology to create a surround house, which integrates audio, video, surround sound, and gesture control, this gives people an immersive 360-degree surround experience. The computation that amd advocates will clear all the obstacles to human-computer interaction, making communication between people, devices, and devices easier and more free.

　Redefinition of Computing

Every day, a large amount of data flow from various Smart terminal devices to the cloud, and better human-computer interaction becomes an urgent need. Mark papermaster, AMD's senior vice president and chief technology officer, said AMD had created a new highly efficient computing method called surround computing, which would redefine modern computing.

Surround computing has made many new developments in human-computer interaction, such as gesture recognition, augmented reality, and virtual reality. Various devices around people are equipped with a more efficient microprocessor, which makes human-computer interaction more intelligent and free from the limitations of time and space, this makes people's digital life more secure, intelligent, and convenient.

The core support for peripheral computing is Apu. AMD has been committed to the integration of CPU and GPU for a long time, and application innovation is achieved through the product Apu. AMD has just released the fourth generation Kaveri Apu. The biggest change is that it supports heterogeneous computing. The CPU and GPU in Kaveri Apu can share memory to achieve memory consistency and achieve more efficient collaborative computing.

At the hot chips conference in 2012, amd proposed the concept and implementation steps of Surround computing. After that, AMD has invested a lot of energy in R & D of related technologies and products along the path of computation, and has made great progress. This is a vivid example of computation. In addition to the shocking audio-visual effect, the appearance of the surround House also shows that the surround computing technology has stepped out of the lab and started to enter the practical stage.

"People can use gestures to control the operations of the entire surrounding house and achieve very friendly human-computer interaction. Surround computing will change the future trend of animation ." Mark papermaster said: "surround computing has several key technologies, including speech recognition, gesture recognition, and facial recognition. The implementation of these technologies depends on the heterogeneous system architecture ."

Creating an immersive virtual world requires huge raw processing capabilities, which requires that computing engines in the future have powerful computing processing capabilities and must also have efficient and energy-saving features. At the just-concluded China International software and information service Fair (cisis) in Dalian, amd provided an example of peripheral computing. For example, AMD's next-generation Kaveri Apu can provide 12 computing cores (including 4 "roller" Architecture CPU cores and 8 GCN architecture GPU cores ), supports mantle visual acceleration and 32-channel surround sound true audio. Based on the heterogeneous system architecture, Kaveri Apu can greatly reduce energy consumption while improving performance.

"If you want to achieve an immersive computing experience, all of the above factors are critical and indispensable. However, this is just the beginning ." "We are at the inflection point of the new computing age," Mark papermaster told reporters. AMD is the creator of Surround computing. We will completely change the future computing mode through computation. Surround computing will create a new product category in the future, mainly serving augmented reality and virtual reality ."

Three key factors for improving energy efficiency

 

All types of Smart terminal devices, including PCs, smartphones, tablets, and even wearable devices, will be an important carrier of peripheral computing. To facilitate communication and mobility, these terminal devices will become smaller and more portable. Therefore, energy-efficient components are required.

Mark papermaster made it clear in his keynote speech at the China International software and information service fair that amd Apu will be 25 times more energy efficient by 2020. To this end, AMD will introduce new innovations in Apu design, energy consumption management, and heterogeneous system architecture design.

AMD will primarily implement its commitment to improving Apu energy efficiency through the following efforts.

First, heterogeneous computing and power consumption optimization. AMD integrates dedicated accelerators such as CPU and GPU computing cores and digital signal processors into a single chip through heterogeneous system architecture to become Apu. AMD's innovation achieves energy saving by canceling the connection between independent chips. The CPU and GPU are in the same computing position, and the computing workload can be seamlessly transferred to the optimal processing component, this improves the efficiency of common workloads.

"AMD has already provided HSA-specific APUs for embedded devices and the PC market, and its semi-customized APUs are also widely used in new-generation game consoles," Mark papermaster said ."

Second, smart real-time power consumption management. For power consumption management, it is vital to complete the task as soon as possible and quickly return to the STANDBY state, and then minimize the standby power consumption. The latest amd Apu can analyze workloads and Applications in real time and dynamically adjust the clock speed to achieve the optimal throughput. Similarly, AMD's platform's inductive power management technology allows the processor to quickly complete tasks through overclocking, and then quickly returns to the low-power STANDBY state.

Third, energy efficiency innovation in the future. Technological innovation is needed to improve energy efficiency. Many years ago, AMD realized the importance of energy efficiency and actively invested in R & D and launched many innovative technologies, including inter-frame power control, multi-domain adaptive voltage, voltage Island, and deep integration of system components. These technologies, coupled with AMD's ongoing innovations in energy efficiency, this will improve the energy efficiency of APU more effectively.

"AMD's strength lies in its ability to improve overall system energy efficiency through innovations in energy consumption control technologies and architectures ." Mark papermaster said, "the most critical innovation is the smart energy management technology that supplies power to the corresponding components on demand. It can accomplish tasks more efficiently, this allows the system to quickly switch to the idle state with ultra-low power consumption to save energy. In addition, the heterogeneous computing technology can continuously improve the efficiency of GPU in parallel computing. The more heterogeneous computing is used, the more effective the energy efficiency is ."

Taking AMD as an example, although 28 nm manufacturing process is also used, the energy efficiency of beema, a new mainstream mobile Apu platform launched in 2014, is 211% of that of the previous generation of kabini platform.

Servers and mobile devices have different ideas on energy-saving design, because the workload of servers is very different from that of mobile devices. The load on the mobile platform is cyclical, while the load on the server is stable.

Based on workload requirements, servers need to be different from mobile device energy management and energy efficiency improvement methods. Mark papermaster said AMD Server products have always been designed to improve energy efficiency as the primary factor. By using an ARM processor and high-density server architecture, more energy efficiency can be achieved.

　Integration brings better application experience

From APU to dual-architecture computing, AMD has been very resolute in implementing its fusion strategy. Both the integration of CPU and GPU and the integration of X86 and arm have led the industry's technological development trend. Mark papermaster said: "The first step of integration is to combine the CPU and GPU, and use a very direct interface to connect the two. However, in the early stage of integration, the CPU and GPU were still in independent memory access. When the fourth generation Kaveri apu was launched, the Memory Sharing and memory consistency were realized, this allows the GPU + CPU to work collaboratively and better support heterogeneous computing."

Both Apu and dual-architecture computing require a wide ecosystem to support and promote their applications. AMD has established partnerships with many software vendors to enhance application development based on APU. "In order to better promote the development and application of HSA heterogeneous system architecture, we established the HSA Foundation to allow partners to better utilize the heterogeneous computing platform and use more advanced programming languages, to achieve better computing results." According to mark papermaster, 40 companies around the world have joined the HSA (heterogeneous system architecture) Foundation. These members share the same ideals as AMD, it is easier to deploy and use heterogeneous computing.

In the past, people often habitually compared AMD with intel. However, from the past few years, the positioning and development ideas of the two companies have greatly changed, AMD has clearly defined the path to integration development.

"Our wish is to bring users a better application experience ." Mark papermaster added, "We provide various energy-efficient computing engines, including CPU, Apu, and graphics cards, to help users implement surround computing more easily. We work with all software developers to develop related applications more easily and run on AMD's energy-efficient computing platform to continuously optimize workloads, it provides a better user experience."
