Lockheed Martin has announced that it will be using NEC’s Artificial Intelligence (AI) based System Invariant Analysis Technology (SIAT) in the aim of improving both its satellites and space travel.

SIAT’s advanced analytics engine, typically used in high-end computer systems and factories, uses data collected from sensors to learn specific behavioural systems that enable the system to automatically detect faults, in addition to recognising resolutions.

“The innovative SIAT developed by NEC can make valuable contributions to solving the challenges faced by Lockheed Martin in the space field,” said Tomoyasu Nishimura, Senior Vice President, NEC Corporation. 

“Going forward, NEC aims to continue strengthening this solution and to globally support safety, security and operational efficiency in a wide variety of fields.”

The US-based giant that specialises in not only aerospace, but also military, defence, security and other advanced technology ventures will aim to utilise the AI tech to rapidly assess how changing space conditions and weather influence the performance of electronics.

“Lockheed Martin and NEC are experts in space and systems, and that's the right blend to explore how AI can improve space products for astronauts and people on the ground,” said Carl Marchetto, Vice President of New Ventures, Lockheed Martin Space.

“AI can revolutionize how we use information from space, both in orbit and on deep space missions, including crewed missions to Mars and beyond.”

The announcement from Lockheed Martin comes within the same week as NASA revealing that it will look to use AI within its own spacecraft in the aim of improving communications with Earth.

Google AI Designs Next-Gen Chips In Under 6 Hours

Google AI’s deep reinforcement learning algorithms can optimise chip floor plans exponentially faster than their human counterparts

In a Google-Nature paper published on Wednesday, the company announced that AI will be able to design chips in less than six hours. Humans currently take months to design and layout the intricate chip wiring. Although the tech giant has been working in silence on the technology for years, this is the first time that AI-optimised chips have hit the mainstream—and that the company will sell the result as a commercial product. 

 

“Our method has been used in production to design the next generation of Google TPU (tensor processing unit chips)”, the paper’s authors, Azalea Mirhoseini and Anna Goldie wrote. The TPU v4 chips are the fastest Google system ever launched. “If you’re trying to train a large AI/ML system, and you’re using Google’s TensorFlow, this will be a big deal”, said Jack Gold, President and Principal Analyst at J.Gold Associates

 

Training the Algorithm 

In a process called reinforcement learning, Google engineers used a set of 10,000 chip floor plans to train the AI. Each example chip was assigned a score of sorts based on its efficiency and power usage, which the algorithm then used to distinguish between “good” and “bad” layouts. The more layouts it examines, the better it can generate versions of its own. 

 

Designing floor plans, or the optimal layouts for a chip’s sub-systems, takes intense human effort. Yet floorplanning is similar to an elaborate game. It has rules, patterns, and logic. In fact, just like chess or Go, it’s the ideal task for machine learning. Machines, after all, don’t follow the same constraints or in-built conditions that humans do; they follow logic, not preconception of what a chip should look like. And this has allowed AI to optimise the latest chips in a way we never could. 

 

As a result, AI-generated layouts look quite different to what a human would design. Instead of being neat and ordered, they look slightly more haphazard. Blurred photos of the carefully guarded chip designs show a slightly more chaotic wiring layout—but no one is questioning its efficiency. In fact, Google is starting to evaluate how it could use AI in architecture exploration and other cognitively intense tasks. 

 

Major Implications for the Semiconductor Sector 

Part of what’s impressive about Google’s breakthrough is that it could throw Moore’s Law, the axion that the number of transistors on a chip doubles every five years, out the window. The physical difficulty of squeezing more CPUs, GPUs, and memory on tiny silicon die will still exist, but AI optimisation may help speed up chip performance.

 

Any chance that AI can help speed up current chip production is welcome news. Though the U.S. Senate recently passed a US$52bn bill to supercharge domestic semiconductor supply chains, its largest tech firms remain far behind. According to Holger Mueller, principal analyst at Constellation Research, “the faster and cheaper AI will win in business and government, including with the military”. 

 

All in all, AI chip optimisation could allow Google to pull ahead of its competitors such as AWS and Microsoft. And if we can speed up workflows, design better chips, and use humans to solve more complex, fluid, wicked problems, that’s a win—for the tech world and for society.
