Common UNIX Architecture Documentation

This is a small compilation of documents, which describe CPU and CPU-near things for individual architectures. I tried to collect them from multiple sources and to use up-to-date versions. But per-se such compilations cannot be complete nor up-to-date, so if you have some document that is not here yet and would fit, just send me mail.

If you plan to mirror this page, please download the premade tarball (34.1 mb) instead, it will save transfer time for both of us.
