In horizontal micro-programming the control word is of the following format: Flag bits Control Signal Bits Next Control Word Address I know that the Control Signal bits denote which micro-operation to execute. My question is does 1 bit of control signal denote ... verify that Scenario 2 is the correct one i.e. 1 control signal bit in horizontal microprogramming denotes 1 micro-operation entirely?
