Nvidia Corp, the world's leading designer of computer chips used in creating artificial intelligence, on Monday showed new research that explains how AI can be used to improve chip design.

The process of designing a chip involves deciding where to place tens of billions of tiny on-off switches called transistors on a piece of silicon to create working chips. The exact placement of those transistors has a big impact on the chip's cost, speed and power consumption.

Chip design engineers use complex design software from firms like Synopsys Inc and Cadence Design Systems Inc to help them optimize the placement of those transistors.

On Monday, Nvidia released a paper showing that it could use a combination of artificial intelligence techniques to find better ways to place big groups of transistors. The paper aimed to improve on a 2021 paper by Alphabet Inc's Google, whose findings later became the subject of controversy.

The Nvidia research took an existing effort developed by University of Texas researchers using what is called reinforcement learning and added a second layer of artificial intelligence on top of it to get even better results.

Nvidia chief scientist Bill Dally said the work is important because chip manufacturing improvements are slowing with per-transistor costs in new generations of chip manufacturing technology now higher than previous generations.

That goes against the famous prediction by Intel Corp co-founder Gordon Moore that chips would always get cheaper and faster.

"You're no longer actually getting an economy from that scaling," Dally said. "To continue to move forward and to deliver more value to customers, we can't get it from cheaper transistors. We have to get it by being more clever on the design."

US Supreme Court Tosses Case Involving Securities Fraud Suit against Facebook

The US Supreme Court sidestepped on Friday a decision on whether to allow shareholders to proceed with a securities fraud lawsuit accusing Meta's Facebook of misleading investors about the misuse of the social media platform's user data.
The justices, who heard arguments in the case on Nov. 6, dismissed Facebook's appeal of a lower court's ruling that had allowed a 2018 class action led by Amalgamated Bank to proceed. The Supreme Court opted not resolve the underlying legal dispute, determining that the case should not have been taken up. Its action leaves the lower court's decision in place, Reuters reported. 
The court's dismissal came in a one-line order that provided no explanation. The Facebook dispute was one of two cases to come before the Supreme Court this month involving the right of private litigants to hold companies to account for alleged securities fraud. The other one, involving the artificial intelligence chipmaker Nvidia, was argued on Nov. 13. The Supreme Court has not ruled yet in the Nvidia case.
The plaintiffs in the Facebook case claimed the company unlawfully withheld information from investors about a 2015 data breach involving British political consulting firm Cambridge Analytica that affected more than 30 million Facebook users. They accused Facebook of misleading investors in violation of the Securities Exchange Act, a 1934 federal law that requires publicly traded companies to disclose their business risks. Facebook's stock fell following 2018 media reports that Cambridge Analytica had used improperly harvested Facebook user data in connection with Donald Trump's successful US presidential campaign in 2016. The investors have sought unspecified monetary damages in part to recoup the lost value of the Facebook stock they held.
At issue was whether Facebook broke the law when it failed to detail the prior data breach in subsequent business-risk disclosures, and instead portrayed the risk of such incidents as purely hypothetical.
Facebook argued that it was not required to reveal that its warned-of risk had already materialized because "a reasonable investor" would understand risk disclosures to be forward-looking statements. President Joe Biden's administration supported the shareholders in the case.
US District Judge Edward Davila dismissed the lawsuit but the San Francisco-based 9th US Circuit Court of Appeals revived it.
The Cambridge Analytica data breach prompted US government investigations into Facebook's privacy practices, various lawsuits and a US congressional hearing. The US Securities and Exchange Commission in 2019 brought an enforcement action against Facebook over the matter, which the company settled for $100 million. Facebook paid a separate $5 billion penalty to the US Federal Trade Commission over the issue.
The Supreme Court in prior rulings has limited the authority of the Securities and Exchange Commission, the federal agency that polices securities fraud.
