Nanoprogramming:

  •  Second compromise: nanoprogramming
  •  it use a 2-level control storage organization
  •  Top level is a vertical format memory
  •  Output of the top level memory process the address register of the bottom (nano- level) memory
  •  Nanomemory uses the horizontal format
  •  Generate the real control signal outputs
  •  The benefit to this method is significant saving in control memory size (bits)
  •  Disadvantage is more difficulty and slower operation (doing 2 memory accesses for each microinstruction)

  • Instance : Assume that a system is being designed with 200 control points and 2048 microinstructions

o   Suppose that only 256 different combinations of control points are ever used

o   A single-level control memory would need 2048x200=409,600 storage bits

  •   A nano programmed system would utilize
  •   Microstore of size 2048x8=16k
  •   Nanostore of size 256x200=51200
  •   Total size = 67,584 storage bits
  •   Nano programming has been used in many CISC microprocessors
