Memory organization and decoding, Operating System

  In a  p system each part (RAM, ROM, I/O) has a unique set of numbers. The allocation of these numbers is usually stated in the form of a memory map. This is a plot of data bus against address.

E.g. Calculate the height and width of the memory map for a 68Hc11  p.

    Since address = A0 -> A15
          data = D7 -> D0
 
  The maximum address is given by: -
 
    216 -1
 
    = 65535 bytes @ 64Kbytes (K = 1024).
 
We can draw this in the form of a memory map difficult i.e. data width horizontal and address
vertically as shown below: -
