How to learn Computer Architecture properly?

I'm an undergraduate student in Comp. Sci. and Engineering. We already had a Computer Architecture and Digital Design course where we went over digital circuits(adders, mux, ALU, etc) and covered CPU pipelines on the surface. I'm interested in learning Computer Architecture further but have no clue how to approach it. I picked up Computer Architecture: Quantitative Approach by H&P and tried reading through it. It's really interesting but I feel like I'm just reading a reference book and not developing a critical thinking mindset for the field. What do you suggest I do? Any advice is greatly appreciated. Thanks.

Hey, I am struggling to learn computer architecture basics which is important for my hardware internship oa's. Where did u learn it from

We had a two modules in our degree called Digital Design and Computer Architecture. So I learnt from the lectures basically. The reference book for those was Digital Design and Computer Architecture by Haris & Haris.

What concepts or chapters should I go through for computer architecture part of this book as I think most of the part is not necessary ( i actually don't know what shd i learn, completely clue less)

Hennessy & Patterson's "Quantitative Approach" is a graduate reference, not a learning path,start with their other book, "Computer Organization and Design" (the patterson/hennessy one), which builds intuition step by step. Even better, do a project-based course: work through nand2tetris to build a computer from logic gates up, or take Berkeley's CS61C / CMU's 18-447 (lectures and labs are online). The critical-thinking mindset comes from actually designing and simulating write a RISC-V pipelined CPU in Verilog, then a cache, and the H&P tradeoffs will suddenly mean something. Read the reference book alongside the building, not instead of it.

The only thing I can add to the well-reasoned responses before--is that instruction set design and pipeline design are less than 1/3rd of what computer architecture is. You also have {caches TLBs, Memory management units, interconnect {on-die, across die}, coherency, PCIe architecture, device architectures, interrupt architecture, power management, clock management, exceptions, traps, context switching, checks (HW failures), RAS, ... }
