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)

Nano programmed machine

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
