size of an architecture depends on

Size of an microcontroller or processor architecture depends on whteher the address bus or data bus or ALU or all the three

  • The "size" of a processor architecture is its word size;

    Thus an 8-bit processor works on an 8-bit word;
    A 16-bit processor works on a 16-bit word;
    etc, etc, ...

    The "word" is the basic unit of data that the processor processes - thus it will be the general register size.

    The address bus is usually bigger than the word size; eg, the 8051 is an 8-bit architecture, but has a 16-bit address bus...
