Control Unit
Consider a microprogrammed control unit has to support 32 number of instructions. For each instruction execution control unit generate a sequence of 64 control words. Each micro instruction contains 3 fields: 118 control signals to support horizontal control unit, a MUX select field to select one of 8 inputs, and a next address field. The size of control memory needed is?

Microprogrammed approach
Microprogrammed control Unit is useful when very small programs are to be run. Shouldn’t this statement be true because microprogrammed approach uses decoder, which slows down speed, so large programs would take more time, and small ones less?
