Microcontroller Architecture and Operation Quiz…

Q: Which of the following is NOT a core component of a microcontroller?

GPU — GPUs are primarily for graphics processing, not core microcontroller functions.

Q: What is the primary function of the CPU in a microcontroller?

Executing instructions — The CPU fetches, decodes, and executes instructions stored in memory.

Q: What is the purpose of RAM in a microcontroller?

Temporary data storage — RAM is used for storing variables and other temporary data needed during program execution.

Q: What is the function of the Program Counter (PC)?

Stores the address of the next instruction to be fetched. — The PC keeps track of the next instruction to be executed.

Q: What is the function of ROM in a microcontroller?

Storing the program code permanently — ROM stores the program code and other data that is non-volatile.

Q: Which of the following is typically NOT an input/output (I/O) peripheral on a microcontroller?

Hard Drive — Hard drives are not typically integrated peripherals on a microcontroller.

Q: What is an interrupt?

A signal that causes the microcontroller to pause its current task and attend to a higher-priority task. — Interrupts allow a microcontroller to respond to external events.

Q: What is an instruction cycle?

The time it takes to execute a single instruction. — The instruction cycle encompasses fetching, decoding, and executing a single instruction.

Q: What is a microcontroller's clock speed measured in?

Hertz (Hz) — Clock speed is measured in Hertz, indicating cycles per second.

Q: What is the purpose of an ALU (Arithmetic Logic Unit) in a microcontroller?

To perform arithmetic and logical operations. — The ALU performs calculations and logical comparisons.
