Intel, RISC-V Rally Rival Groups

Intel and RISC-V backers announced rival alliances to nurture competing ecosystems around tomorrow's processors.

Intel initiated Compute Express Link (CXL), an open chip-to-chip interconnect that it expects to use on its processors starting in 2021 to link to accelerators and memories. Other members include Alibaba, Cisco, Dell EMC, Facebook, Google, HPE, Huawei, and Microsoft.

Separately, a handful of RISC-V proponents launched the CHIPS Alliance, a project of the Linux Foundation to develop a broad set of open-source IP blocks and tools for the instruction set architecture. Initial members include Esperanto, Google, SiFive, and Western Digital. CHIPS stands for Common Hardware for Interfaces, Processors, and Systems.

The CHIPS Alliance is, by far, the most ambitious of the two efforts and is just one of several open-hardware initiatives in the works at the Linux Foundation. CHIPS aims to create open-source blocks for a variety of embedded cores as well as multi-core SoCs capable of running Linux — and, ultimately, an open-source design flow to build and test them.
