    This topic explains the computer operation, interconnection of buses, addressing techniques, flags, condition codes, status registers, storage units, subroutine calls, interrupts, pipelined computers, RISC architecture, CISC architecture, security and protection.


    • Processing and Control Unit

      The central processing unit (CPU) is a part of the computer architecture that performs as an electronic circuitry within a computer. It carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

      The Components of Central Processing Unit

      Fetch-Execute Instruction Cycle



      Interconnection Buses



      Addressing Techniques

      The most common addressing techniques are:

      1) Implied and Immediate Addressing Modes



      2) Direct or Indirect Addressing Modes


      3) Register Addressing Modes


      4) Register Indirect Addressing Mode


      5) Auto-Increment and Auto-Decrement Addressing Modes


      6) Displacement Based Addressing Modes




      Flags, Conditions Codes and Status Registers

      Flag

      Name

      Description

      Z

      Zero Flag

      Indicates that the result of an arithmetic or logical operation (or, sometimes a load) was zero.

      C

      Carry Flag

      Carry/borrow. Set with a carry from an addition or borrow from a subtraction.

      S/N

      Sign Flag

      Negative Flag

      Indicates that the result of a mathematical operation is negative.

      V/O/W

      Overflow Flag

      Overflow. Set if a 2’s complement overflow condition is generated.


    • Self Check - Topic 6 Forum

      Discuss the function of memory, cache memory and virtual memory.


    • Summary
