Understanding Microarchitecture of legacy IPs

[curious_mind]

I was going through the website https://github.com/TobiFlex/TG68K.C, which claims to have implemented 68000, 68010 and 68020.
I was interested to know the details of its micro architecture. Can anybody guide how to do so?

I searched the phrase "68000, 68010 and 68020 micro-architecture" and got a few links where further info is available. In one of them you need to sign up to obtain a free e-book on the 68K.
Did you try out such links?

could you provide details. I am interested in 68020

I found this after a couple of minutes of going through various links using a search on "68000,68010,68020".

You need to learn how to effectively use a search engine and parse the results. This link didn't appear on the first page of results.

I already have this book 68000,68010 and 68020 primer. This book covers assembly programming in detail. I am actually looking for microarchitecture, Viz. design of controller and the datapath.

A much simpler example is the 6502, and there are some good guides to the architecture. A number of years ago I used this to build a 6502 into an ASIC, back before everything had ARMs. Worked great, if you don't mind 8-bit math.
