At the just concluded annual devsummit Technology Conference of arm, arm shared the great success of project Cassini. With the participation of leading chip and equipment manufacturers in the edge supply chain of Internet of things and infrastructure, the number of partners participating in the project has doubled, from 30 12 months ago to more than 70.

So far, arm partners have shipped more than 200 billion chips, most of which are used in devices for daily life applications. With the wide application of ARM Technology in the field of Internet of things, the scene of “100% of the world’s shared data will soon be processed through arm technology” is further consolidated.

Mohamed Awad, vice president of arm Internet of things and embedded business unit, said: “In order to give full play to the potential of the Internet of things and edge technology, it must be expanded at a faster development and deployment speed than at present. In the process of delivering these systems, there is a long list of challenges to be solved, including embedded software, cloud services, hardware design, connectivity, machine learning, security, etc., while many challenges are slow to be solved due to complexity, fragmentation or other problems. This is arm The reason for launching Cassini project in 2019 is to solve the key friction points of realizing cloud native software experience in a secure arm edge ecosystem by uniting the strength of the industry. What excites me most this year is that we have seen some partners focusing on ‘far edge’ gateways and endpoints join the project, including several large ODM manufacturers around the world. “

Moving towards the primary edge of the cloud

The industry is clearly aware of the benefits of scalable, on-demand blueprints in achieving large-scale software deployment, as well as the benefits of a consistent API development method to ensure the security of devices from scratch. The development and adoption of Cassini project clearly reflects the importance of its three development priorities to the industry. The first is standardization.

Arm systemready is a standardization program designed to ensure that operating systems are deployed to edge devices based on ARM architecture in a consistent manner so that hardware and software can operate at the bottom of arm based technology. Today, the plan has achieved some important milestones:

·Since the launch of this program with two early partners last year, 26 different categories of systemready devices have been certified.

·ARM chip partners ampere, Broadcom, Marvell, NXP and Ruixin microelectronics have obtained systemready certification in the evaluation suite of some of their leading chips, laying the foundation for their customers to obtain certification more easily for their products using these chips.

·More than 10 leading ODM manufacturers have promised to use systemready to certify a variety of products in their product portfolio, including Yanyang technology, Advantech technology, avantek, compub, Gigabyte technology, hawkketech, Kontron, Lenovo, pine64, raspberry PI and solidrun. At present, there are dozens of commercial certified products in the market.

·In addition to red hat, VMware and windows, other commercial operating systems now using arm systemready include Debian, Fedora, openSUSE and yocto Linux.

Security is critical for scalable edges

For scalable edge, security is as important as system standardization, especially the attacks on edge applications are becoming more and more frequent and complex. At present, more than 50 partners including chip suppliers, software suppliers and equipment manufacturers have launched more than 80 PSA certified products in the market. This year, the two partners silicon labs and Italy France semiconductor passed PSA level 3 certification for the first time, realizing the highest level of security protection of IOT hardware and software, reflecting that the industry is investing heavily in basic security.

Another key component of Cassini project security is parsec, which complies with PSA certification specification. It allows software developers not only to maintain the portability of software, but also to use excellent security functions to directly apply to their applications. Parsec is the official sandbox project of the cloud native Computing Foundation (CNCF). After the conceptualization of arm, it has been adopted by the open source community and integrated with Fedora, openSUSE, yocto Linux and other operating systems.

Participate in promoting innovation

Taking a standardized approach to system architecture and security is the benchmark of Cassini project, and the real cloud native reference implementation scheme and blueprint brought by ecosystem collaboration can help developers realize the vision of security edge based on ARM architecture. Many industry partners have provided new reference implementation solutions to support key edge application scenarios, including artificial intelligence edge application scenarios developed in cooperation with NVIDIA and rancher, high-performance edge reasoning application scenarios developed in cooperation with redis, and computing integration application scenarios developed in cooperation with VMware.

The success of Cassini project at the edge of infrastructure and the Internet of things market has had a chain reaction in other fields. It is worth noting that the participation of the whole ecosystem is not limited to hardware companies such as chip suppliers and ODM manufacturers; Many OEMs, cloud service providers (CSPs) and other key software providers are now fully involved in Cassini project and similar new projects led by arm for automobile and Cortex-M ecosystem:

·Recently, through collaboration with leading automotive supply chain enterprises, arm announced the launch of scalable open architecture for embedded edge (soafee), a collaborative project based on Cassini project, which is used to define a cloud native architecture compatible with the safety criticality and real-time requirements of software defined vehicles.

·The newly released project Centauri focuses on driving the exponential growth of cortex-m-based devices. As a key component of the new arm Internet of things comprehensive solution, Centauri project combines the standard, safe and extensive software ecosystem to help the system based on Cortex-M achieve the contribution similar to that made by Cassini project for cortex-a system.

The diversity of the arm ecosystem has brought many technological innovations that are taken for granted today. Cassini project aims to provide an extensible and secure framework for arm partners to build future computing solutions. The progress made so far is only the beginning and the future is promising. The project will continue to promote the development of standardization, security and ecosystem collaboration to meet the changing computing needs from cloud to edge and terminal devices.
