 1. ALU  2. STACK POINTER 3. PROGRAM COUNTER 4. INSTRUCTION REGISTER AND DECODER ALU ( ARITHMATIC AND LOGIC UNIT ) It is 8 bit unit  In this arithmetic and logical operation are carried out . ALU contain the binary adder to perform addition substracion by 2’s complement method Data is supplied by memory devices and input ouput devices The result is typically stored in the accumulator. STACK POINTER:- Stack poiointer is a 16 bit register which contain the address of top of stack With the help of incrementer and decrementer stack pointer perform their work The stack pointer is incremented when data is push  The stack pointer is decrementd when data is pop. INSTRUCTION REGISTER AND DECODER :- During the instruction fetch, the first 8 bit of instruction is transfer to the 8 bit instruction register The content of instruction register are available to the instruction decoder The output of decoder get by timing signals, ALU & data buffer. PROGRAM COUNTER:- Program coun...
