The Libre-SOC project, a team of engineers and creative personas aiming to provide a fully open System-on-Chip, has today posted a layout that the team sent for chip fabrication of the OpenPOWER-based processor. Currently being manufactured on TSMC’s 180 nm node, the Libre-SOC processor is a huge achievement in many ways. To get to a tape out, the Libre-SOC team was accompanied by engineering from Chips4Makers and Sorbonne Université, funded by NLnet Foundation.
Based on IBM’s OpenPOWER instruction set architecture (ISA), the Libre-SOC chip is a monumental achievement for open-source hardware. It’s also the first independent OpenPOWER chip to be manufactured outside IBM in over 12 years. Every component, from hardware design files, documentation, mailing lists to software, is open-sourced and designed to fit with the open-source spirit and ideas.
This is an impressive milestone, and I can’t wait until this is ready for more general use. With things like RISC-V and OpenPOWER, there’s a lot of progress being made on truly open source hardware, and that has me very, very excited. This also brings an OpenPOWER laptop closer to being a real thing, and that’s something I’d buy in less than a heartbeat.
