memory-mapped I/O and polling, write a program that reads characters directly from the keyboard. To demonstrate how slow the keyboard device is, print the character pressed and the number of iterations after exiting the wait_keyboard loop. Repeat the execution of the program until the newline character is pressed. Make sure to activate the “Keyboard and Display MMIO Simulator” and to run the MARS simulator at maximum speed.
