Detailed explanation-1: -The type of control signal are generated based on, a)contents of the step counterb)Contents of IRc)Contents of condition flagsd)All of the mentionedCorrect answer is option ‘D’.
Detailed explanation-2: -There are two approaches used for generating the control signals in proper sequence as Hardwired Control unit and the Micro-programmed control unit.
Detailed explanation-3: -Three control signals are RD, WR & ALE.
Detailed explanation-4: -The hardwired control unit uses the logic circuit so that it can generate the control signals, which are required for the processor. The micro-programmed CU uses microinstruction so that it can generate the control signals. Usually, control memory is used to store these microinstructions.
Detailed explanation-5: -The control unit generates the appropriate timing and control signals to all the operations involved with a computer. The flow of data between the processor, memory, and other peripherals is controlled using the timing signals of the control unit.
