Is Rivos Building an RISC-V AI Chip? - Slashdot

Apr 21, 2024 - hardware.slashdot.org
Chip startup Rivos has raised $250 million in a funding round, which will be used to manufacture its first server chip for artificial intelligence. The chip combines a CPU with an AI-accelerating component optimized for LLMs and data analytics. Rivos plans to design chips based on the RISC-V architecture, an open-source alternative to architectures made by Arm, Intel, and Advanced Micro Devices. This approach means Rivos will not have to pay a license fee to Arm.

In related news, Allen Wu, former CEO of Arm China, is rumored to have founded a new company, Zhongzhi Chip, which is attracting talent from Arm and forming alliances with several global RISC-V chip developers. The company's operational focus is unclear, with speculation around whether it will engage in its own R&D initiatives or represent Tenstorrent in China as its agent, developing HPC CPUs and AI processors based on the RISC-V ISA.

Key takeaways:

  • Chip startup Rivos has raised $250 million in a funding round to manufacture its first server chip geared for artificial intelligence, after settling a lawsuit with Apple earlier this year.
  • Rivos plans to design chips based on the RISC-V architecture, an open source alternative to architectures made by Arm, Intel, and Advanced Micro Devices, which will save them from paying license fees.
  • Lip-Bu Tan, founding managing partner at Walden Catalyst, one of Rivos' investors, plans to build a software-defined hardware ecosystem for RISC-V, similar to what CUDA did with Nvidia.
  • Former chief executive of Arm China, Allen Wu, is rumored to have founded a new company, Zhongzhi Chip, which is attracting talent from Arm and is speculated to be developing chips based on RISC-V.
