Is there some way to better understand TAOCP Vol 1 by Knuth?

Reposting:

Hello, I am far from a smart person but I still wanted to give reading The Art Of Computer Programming Volume 1: Fundamental Algorithms by Donald Knuth a try but I don't understand at all how MIX computer he talks about works.

Are there any other resources that make it easier to understand the contents of this book?

TAOCP is a product of its time. While the concepts are timeless, and as such still relevant today, MIX is similar to how many programmers built software back in the 1970s: with assembly code. If TAOCP was written today, it probably would use something else.

The good news is that, even though 1970s-era MIX assembly is much different than even modern assembly, it's pretty simple. The most confusing part is the field manipulation part of the instructions. Don't get hung up trying to memorize all of the instructions; take a look at the examples in the text, which are commented to say what they are actually doing.

My strategy when reading TAOCP: if I get stuck, move on to the next section, and come back to it later when I've had time to sleep on it...

MIX/MMIX is assembly language level programming.

---------

Per GNU MIX development kit (mdk)[0] intro "... a set of utilities for developing programs using Donald Knuth’s MIX mythical computer and MIXAL, its assembly language." The tutorial goes over architecture, instruction set, MIXAL related stuff and basic "getting started".

Something a bit above "bare metal programming"; Escape is an OS that runs on GIMMIX as a simulator for MMIX.[7]

DXL is a similar architechture.[1]

MMIX is more 'current'[2] aka easier to find tutorial information on RISC architectures.

Few 'intro to computer architecture'[3] -- depends on how want to approach. aka, high level overview, how things work 'bitwise" vs. abstract level one step above the bits, "stack"/instructional queue
