    I have searched on internet. I saw this example. but I don't understand clearly.can some one give specif example to understand about PC
    Example: Intel IA32
    The Intel IA32 (better known by some as "x86") is a CISC architecture, which means that each instruction can be a
    different length. The Intel memory is byte-addressable. Each cycle the instruction decoder needs to determine the
    length of the instruction, in bytes, and it needs to output that value to the PC. The PC unit increments itself by the
    value received from the instruction decoder.
