    N Bit ALU

    please some one check out this table. and tell me its correct or wrong ? I read in every blog that processor made with ALU and control unit. so after some reading I made this table. i am not going to make for company. I am just going to make specific one for my basic understanding

    machine language to assembly language

    I think its ram address (The 0000, 0002, 0004 etc are the memory addresses) where data will be store how we access memory and which instruction we use that determine weather we are accessing Internal rom , Internal Ram or SFR
