Q50 / 100
What is "memory-mapped I/O"?
Correct! Well done.
Incorrect.
The correct answer is A) A technique where hardware peripherals' registers are mapped into the same address space as memory, allowing the CPU to interact with peripherals using standard memory read/write instructions
A
Correct Answer
A technique where hardware peripherals' registers are mapped into the same address space as memory, allowing the CPU to interact with peripherals using standard memory read/write instructions
Explanation
Memory-mapped I/O lets developers control hardware (e.g., set a GPIO pin) by writing to specific memory addresses, simplifying interaction with peripherals using the same instructions used for RAM.
