What is the book on the description of the low-level operation of the computer?

Question

Books

Hello!
I want to understand in detail how it works, a computer, a program on it. Please advise a book that describes in detail how the calculations take place in the processor, how what is transferred from the processor to the RAM, etc. I want to write my own virtual machine for learning purposes, but first I want to understand the details and trifles.
Thanks in advance
