Microprogrammed Control Quiz

What is microprogrammed control?

• A type of software used to control the temperature of a computer

• A control mechanism that uses a microprogram to control the operations of the hardware.

• A method of controlling a computer using only hardware components

• A type of control used in large-scale industrial machinery

What are the advantages of microprogrammed control?

• Limited ability to modify control signals

• High cost of implementation

• Inflexibility in adapting to changes

• Flexibility in modifying control signals

How does microprogrammed control differ from hardwired control?

• Microprogrammed control uses a control memory to store microinstructions.

• Microprogrammed control uses a control register to store microinstructions.

• Hardwired control uses a control memory to store microinstructions.

• Microprogrammed control does not use any memory to store microinstructions.

What is pipelining in computer architecture?

• Overlapping execution of multiple instructions

• Simultaneous execution of multiple instructions

• Random execution of multiple instructions

• Sequential execution of multiple instructions

Explain the concept of instruction pipelining.

• Instruction pipelining is a concept that allows instructions to be processed in a random order in a microprocessor.

• Instruction pipelining is a technique used to slow down the processing of instructions in a microprocessor.

• Instruction pipelining is a method used to execute only one instruction at a time in a microprocessor.

• Instruction pipelining is a technique used in microprocessor design to allow multiple instructions to be processed simultaneously by dividing the execution of instructions into a series of independent stages.

What are the benefits of pipelining in computer architecture?

• No impact on performance

• Causes system crashes

• Improves overall performance

• Decreases overall performance

What is data hazard in pipelining?

• A type of computer virus

• Dependency causing a stall in the pipeline

• A method for increasing pipeline efficiency

• A hardware malfunction in the pipeline

How can data hazards be resolved in pipelining?

• By increasing the clock speed of the processor

• By reducing the number of pipeline stages

• By adding more memory to the system

• By using techniques such as forwarding, stalling, and reordering instructions.

What are control hazards in computer architecture?

• Memory leaks in the system

• Overheating of the CPU

• Pipeline stalls or redirection due to delays in branch instructions

• Incorrect data input from the user

How can control hazards be mitigated in computer architecture?

• By using techniques such as pipelining, branch prediction, and forwarding.

• By using water cooling systems

• By adding more RAM to the computer

• By increasing the clock speed of the processor
