In Shift to New Era, Wave Computing Adopts RISC-V Chip Architecture

Silicon Valley's Wave Computing said on Tuesday it is launching designs for two new microprocessors this year using RISC-V architecture as it sunsets its once-popular MIPS architecture.

The move adds to growing momentum for RISC-V, an open-standard instruction set architecture (ISA) and emerging rival to proprietary architecture from Britain's Arm, the semiconductor technology firm owned by SoftBank Group Corp.

RISC-V's nascent but growing popularity owes much to its free and open-standard nature. It is also in focus due to its potential to help China build up its own semiconductor industry as Chinese companies developing technology based on the architecture could be shielded from US export controls.

Wave's MIPS architecture, developed in the lab of Stanford University professor John Hennessy, the current chairman of Alphabet Inc, is now over 35 years old.

It has fallen behind Arm's architecture, which rules in the mobile chip world, and x86 - initially developed by Intel Corp - which dominated laptop and data center chips. After being owned by a string of companies, MIPS was bought by Wave which ended up in bankruptcy in 2020 and emerged from it early last year.

"In order for the company to continue to exist, it needed to find another way to be able to fight this ecosystem battle that it lost," Desi Banatao, who took over as CEO of Wave after its bankruptcy, told Reuters in an interview.

He added that the company has already inked a contract to supply one of the new processor designs to an automotive tech firm.

Sanjai Kohli, Wave's former CEO, said the MIPS and RISC-V instruction sets are close enough that the company was able to easily modify many of the MIPS processors it owns.

Intel has backed RISC-V, investing in the ecosystem as part of the launch of a $1 billion fund to support companies with disruptive technologies as it builds up its foundry business.

RISC-V also gained more attention after Nvidia Corp's bid to buy Arm heightened concern about the potential for the chipmaker to control Arm's architecture. The bid has since failed after being rejected by regulators.

The State Department is warning US diplomats of attempts to impersonate Secretary of State Marco Rubio and possibly other officials using technology driven by artificial intelligence, according to two senior officials and a cable sent last week to all embassies and consulates.

The warning came after the department discovered that an impostor posing as Rubio had attempted to reach out to at least three foreign ministers, a US senator and a governor, according to the July 3 cable, which was first reported by The Washington Post.

The recipients of the scam messages, which were sent by text, Signal and voice mail, were not identified in the cable, a copy of which was shared with The Associated Press.

“The State Department is aware of this incident and is currently investigating the matter,” it said. “The department takes seriously its responsibility to safeguard its information and continuously takes steps to improve the department’s cybersecurity posture to prevent future incidents.”

It declined to comment further due to “security reasons” and the ongoing investigation.

One of the officials said the hoaxes had been unsuccessful and “not very sophisticated.” Nonetheless, the second official said the department deemed it “prudent” to advise all employees and foreign governments, particularly as efforts by foreign actors to compromise information security increase.

The officials were not authorized to discuss the matter publicly and spoke on condition of anonymity.

“There is no direct cyber threat to the department from this campaign, but information shared with a third party could be exposed if targeted individuals are compromised,” the cable said.

The FBI warned in a public service announcement this past spring of a “malicious text and voice messaging campaign” in which unidentified “malicious actors” have been impersonating senior US government officials.

The scheme, according to the FBI, has relied on text messages and AI-generated voice messages that purport to come from a senior US official and that aim to dupe other government officials as well as the victim’s associates and contacts.

It is the second high-level Trump administration official to face such AI-driven impersonation.

The government was investigating after elected officials, business executives and other prominent figures received messages from someone impersonating President Donald Trump’s chief of staff, Susie Wiles. Text messages and phone calls went out from someone who seemed to have gained access to the contacts in Wiles’ personal cellphone, The Wall Street Journal reported in May.

Some of those who received calls heard a voice that sounded like Wiles, which may have been generated by artificial intelligence, according to the newspaper. The messages and calls were not coming from Wiles’ number, the report said.
