    I have question how to design Instruction set (just for paper work)

    I chose 8 bit instruction with 8 instruction 4 for arithmetic operations and 4 for logic operation

    1)what should be operand and opcode ?
    2)what should I know before to design ?

    Your first step is to know how many instructions you can have with an 8 bit instruction length. (hint: it's not 8)

    You really need to go back and learn something about microcontrollers before trying to design one.
