Computer Organization and Design RISC-V Edition

   You can select the assembly output (I like RISCV but you can pick ARM, x86, mips, etc with your choice of compiler) and write your own simple functions. Then put the original function and the assembly output into an LLM prompt window and ask for a line-by-line explanation.

   Also very useful to get a copy of Computer Organization and Design RISC-V Edition: The Hardware Software Interface, by Patterson and Hennessy.

   And on a semi-related note, Patterson and Hennessy's "Computer Organization and Design (RISC-V Edition)" is an updated classic introduction to computer architecture (and its sequel is legendary.) I also recently discovered Harris and Harris' Digital Design and Computer Architecture (RISC-V Edition), and its follow-on lab courses, RVfpga and RVSoC, which cover implementation on an FPGA board and/or simulator.

   Love the Harris and Harris book!

   I might add these:

   - Computer Architecture, Fifth Edition: A Quantitative Approach - https://dl.acm.org/doi/book/10.5555/1999263

   - Computer Organization and Design RISC-V Edition: The Hardware Software Interface - https://dl.acm.org/doi/10.5555/3153875

   both by Patterson and Hennessy

   Edit: And if you want to get into CPU design and can get a grip on "Advanced Computer Architecture: Parallelism, Scalability, Programmability" by Kai Hwang, then i'd recommend that too. It's super old and probably some things are made differently in newer CPUs, but it's exceptionally good to learn the fundamentals. Very well written. But I think it's hard to find a good (physical) copy.

   If you want to be fluent in bare-metal, you must know the bare metal. Writing functions in bare metal provides performance boost over compilers only if know how to match the computation and data to the underlying architecture better than the compiler. Assembly is just a way to write it down.

   There are two recently updated great books I recommend:

   - Computer Architecture: A Quantitative Approach (2017) by Hennessy & Patterson

   - Computer Organization and Design - RISC-V Edition (2017) by Hennessy & Patterson (I have the older MIPS edition)

   You also need a book and documentation for the specific architecture (x86 or ARM), but the two books above teach generic stuff that is useful everywhere.

   If you do numerical HPC programming, you usually write very little assembly. You might add some some inline Assembler tweaks inside (C/C++/Fortran) functions when needed. You must know to program in C, C++ or Fortran depending on what the code base you are working on uses and how to embed assembly code inside them.

   EDIT: CUDA programming might be important to learn if you want to do low level numerical programming.

   Maybe this book: Computer Organization and Design - RISC-V Edition ? On Amazon: https://www.amazon.co.uk/Computer-Organization-Design-RISC-V...
