Terminology: "registers" in assembly language programming -


I have heard terminology: register, hardware register, program register, register file.

What is the difference between all these? And in the website, what is the type of ex register? Program register?

There is a storage area inside a register CPU. Here are some definitions:

  • A register file is an array of registers - see for a complete description.
  • The eX Register CPU is the registrant register of Intel x86 family - this is where integer mathematics is done.
  • Program register (I think that you mean program counter) is a special purpose register in which the next machine code instruction is to be detected
