Before learning Assembly, I think it would be useful to learn a bit about different components of CPU in general. If we think of CPU as a black box its main function is to fetch instructions from RAM which are in the form of machine code and execute them. Components of CPU Arithmetic Logic Unit (ALU) Memory Management Unit (MMU) Control Unit (CU) Registers Clock Cache Buses 1. Arithmetic Logic Unit (ALU) ALU is an electronic circuit made of NAND gates responsible for performing arithmetic and logical operations on integer binary numbers. It takes two operands as inputs and an opcode to indicate the type of operation to be performed. Operations supported by ALU are Add, Subtract, Negation, Two’s complement, AND, OR, XOR, bit shift, etc. ...
