Hi All,

I am trying to troubleshoot some high CPU on some of our kit.

As part of this I am trying to locate some sort of reference guide that explains what each of the processes are and their function / purpose.

Yes I know this would generally be answered on a case by case sort of basis with a TAC case but I prefer to have a deep understanding myself as well.

Has anybody come across such a document? I am really after this for any cisco kit such as routers, switches, asa.

It's been several years since I've been to a Networkers conference, but there used to be a Cisco presenter who perennially delivered a presentation that dove into just what you are asking. I remember him going into process switching, fast switching, CEF, line card differences, hardware vs software-based processes, etc.

If you have any colleagues with access to previous years' Networkers presentations, you might scour that source. Sorry this answer doesn't help a lot right this moment, but do consider Networkers (aka Cisco Live!) in the coming year. It is really an invaluable source of inside Cisco training "not available in stores".
