Control Words and Groups in Microprocessors

What is the primary purpose of a control word in a microprocessor?

• To define the operation of peripheral devices

• To store data

• To increase processing speed

• To manage memory allocation

In the context of microprocessors, what does the term "control group" refer to?

• A group of data lines

• A set of control signals used for operation

• A collection of CPU registers

• A set of memory addresses

Which component typically generates control words for the microprocessor?

• Memory

• I/O Ports

• Control Unit

• Arithmetic Logic Unit (ALU)

What is a common function of a control word in I/O operations?

• To specify the direction of data transfer

• To perform arithmetic calculations

• To manage memory access

• To handle interrupts

How does a control word influence a peripheral device?

• It directly changes the device's data

• It configures the device's operational mode

• It alters the device's power supply

• It increases the device's speed

Which of the following is NOT typically controlled by a control word?

• Data transfer mode

• Memory access time

• Device status

• Peripheral device configuration

In a microprocessor, what is the role of the control unit with respect to control words?

• To execute arithmetic operations

• To generate and decode control words

• To manage the memory hierarchy

• To store data temporarily

How are control words typically transmitted to peripheral devices?

• Via data buses

• Through address lines

• Using control signals

• Via interrupt requests

What effect does a control word have on a microprocessor's I/O ports?

• It changes the memory address

• It configures the mode of data transfer

• It alters the clock speed

• It manages CPU instructions

In a microprocessor system, what is the relationship between control words and control signals?

• Control words are used to generate control signals

• Control signals create control words

• They are unrelated

• Control signals are stored as control words
