In the age of artificial intelligence, PSA platform uses 'core' to guard safety
The future is the era of artificial intelligence, according to the survey showed that 50% of people think drone safer, 47% of people are more inclined to AI doctors, then the safety is the top priority, so arm recently introduced the first Industry common framework - platform security architecture PSA, to create secure Internet devices, with 'core' to protect the Internet of Things industry security.
According to statistics, arm ecosystem partners have shipped more than 100 billion arm-based chips so far and expect to ship another 100 billion arm-based chips between now and 2021. This also means arm and arm ecosystems The important task to be done together to ensure that increasingly diverse interconnected devices can be based on a common security foundation.Arms that the entire industry from end to cloud value chain, security should not be an afterthought.
Despite this, more and more Internet-enabled devices, while pursuing security, are hoping to retain their diversity of innovation and uniqueness, and arm launches its first industry-standard framework, the Platform Security Architecture PSA, Platform Security Architecture) to create secure connected devices, aiming to lay a credible foundation for the interconnectedness of all things and to accelerate the ambitious vision of a trillion-trillion devices worldwide by 2035. To achieve this vision, not only There is a need for more people to protect the security of their devices and to convince people that the technology industry is doing its best to protect it, which is not easy because it requires constant hassle with hackers, and they are endlessly looking for loopholes and It intrudes into our lives as a starting point.
PSA provides a representative IoT threat model and security analysis; hardware and firmware architecture specifications based on key security principles define best practices for designing endpoint devices; Trusted Firmware-M, an open source reference compliant with the firmware specification The industry leader in China already supports PSA. The arm is taking a proactive approach to enabling its partners to thoroughly test the PSA architecture in hopes of formally unveiling the specifications and the public version of the software in the first quarter of 2018. Arm and Ecosystem partners and the industry as a whole have to step up their footsteps and all aspects of the industry value chain need to follow the guidelines and security is no longer an option.
Edge computing gets warmer, Mbed Edge enables edge-side gateway management
In the IoT applications, we see great opportunities for the development of business buildings, precision agriculture and interconnection sites, smart home applications, etc. Correspondingly, edge computing gradually enters the field of vision. Edge computing is the management of cloud computing systems Update, and data processing done at the 'edge' of the network closer to the data source.Using local processors and storage as the primary computing device for the application reduces the time to transfer all information back and forth from the central remote data center. The more complex and need to handle more data, the use of local computing power can help reduce the delay.For example, artificial intelligence program, the algorithm can make hundreds of decisions in a second.In industrial production, multiple processors simultaneously receive input and Coordinate Response In the AR system, the program synthesizes HD graphics and geospatial data in real time.
First, it allows gateways to drive simple applications without the need for cloud-based commands, such as a simple rule of thumb to monitor the pressure level in the production line, and if the pressure reaches a certain threshold, it can Cut off the entire production line, this rule should be in the working state regardless of the cloud is available.Secondly, in many cases, the original data stream does not have to pass through the cloud, but can be processed at the edge, especially when passed When traffic on a network (such as a cellular network) is connected to the cloud.
To this end, arm extends Mbed Cloud's IoT device management capabilities to enable Mwit Edge's IoT gateways for device access, control and management. Mbed Edge has three key capabilities: Non-IP network protocols, edge computing and Gateway management.
Protocol Translation: Many traditional networking devices use incompatible protocols such as Modbus and BACnet for communication protocols. Mbed Edge can translate these protocols so they are managed by Mbed Cloud just as IP-based protocols do.
Gateway Management: Mbed Edge's new set of features enhances IoT Gateway's continuous service capabilities to minimize costly downtime Key capabilities include early warning notification, process, resource and interface management, and detailed local diagnostic capabilities.
Edge computing: Mbed Edge will provide local application execution environment and related computing resources, so that the gateway can be on the rules of computing and data processing.Thus, even if the local network is disconnected from the external network, the local business can continue, reduce Impact on productivity.
With regard to future planning, arm said Mbed Edge plans to achieve two major capacity development, one is related to equipment, the other is involved in the cloud, especially for identification, access path management, and other related capabilities, arm will add another management to Above the device, realize gateway management and communication of the device.
Four disruptive technologies to promote display technology innovation
As content on smartphones is increasingly being played on a daily basis, browsing mobile content in a variety of indoor and outdoor environments is a challenge we face. From virtual reality games to HDR video playback, high-quality content presentations Excellent user experience is crucial.After all, the wonderful visual experience mobile display technology is a major new device is a major selling point. Arm observed several disruptive trends are driving the innovation of display technology:
VR headsets must keep the screen close to both eyes, so in order to ensure the quality of the viewing image, more pixels must be present in the same area of the screen.In addition, in order to reduce overall latency and achieve lower image blur on the LCD VR panel, Requiring high frame rates up to 120 frames per second.Virtual applications are arguably an unprecedented multiple of pixel requirements for VR applications over non-VR applications, resulting in significant design complexity and system bandwidth increases. This poses a significant challenge to the energy efficiency and cost per unit area of mobile devices.
High Dynamic Range (HDR) is a key step in improving image fidelity, and HDR gives images more full color and brightness for closer to the user's experience Because the display panel does not function as a panel The same, if you want at the same time in HDR and SDR display can browse HDR content display subsystem will cause challenges.
Multiple Window Mode, previously only available on desktop computers, allows multiple execution tasks to be rendered on the screen at the same time Window size adjustments and settings depend on the limits defined by the application and system control From the system design level , It's important to launch multiple windowing features, and the enhanced Android Window Composition feature in advanced display solutions allows users to perform multiple tasks on their mobile devices and achieve the same desktop-like Efficiency experience.
The wide variety of types of panels and interfaces requires continued growth in support for display technology, especially as it becomes more complex and requires functional optimization across application-processor and panel display-driven interconnects.From HDR To the SDR, if the media were to be able to render the full color and clear image we were looking for, the display pipeline had to output the content correctly according to the panel's efficiency and intelligently avoid unnecessary bandwidth waste.
These trends not only increase the throughput requirements, but also harsh test of the overall system performance, but also to take an integrated strategy arm display solutions to create market opportunities.
