Some of my recent long-term projects revolve around a little known CPU architecture called ‘Lanai’. Unsurprisingly, very few people have heard of it, and even their Googling skills don’t come in handy. This page is a short summary of what I know, and should serve as a reference for future questions.
Deeply fascinating. I love obscure CPU architectures, and they don’t come more obscure than this.
AMD Am29000 is my favourite obscure ISA.
The TrueBit project mentioned in that article has some information about the Lanai intructions:
