Here’s a report <https://www.nextplatform.com/2020/04/02/tachyum-starts-from-scratch-to-etch-a-universal-processor/> on a startup creating another new, proprietary processor architecture. Proprietary or not, the standard thing to do to get software running on things like this seems to be to port the GNU toolchain. Kernel? OS? No mention of that at this stage. I don’t claim to understand all the details, but it seems to be taking ideas from lots of sources, including Intel’s Itanium (which failed to become a successor to x86). One thing I was surprised to learn is that, as the wires connecting the transistors on a chip get thinner, this also makes them slower. So you don’t get all the gain you were expecting from making them shorter and bringing things closer together. One thing is clear: the Great Wheel Of Reincarnation <https://www.deviantart.com/default-cube/art/Computer-Graphics-And-The-Wheel-Of-Reincarnation-654204041> (which in this case would apply to computing generally, not just graphics) has yet to stop spinning ...
