    How assembly instruction convert into binary

    I know the assembler convert assembly instruction into machine code (MOV A, #10H convert in machine code like 01010101). But I want to know how assembler convert MOV A, #10H into 01010101?(internal process of hardware) How the hardware of microcontroller works with assembler?
