Solutions to Chapter 16 | Low Level 16 4 Write a step by step execution of things that happen after a user presses a key on the keyboard Use as much detail as possible SOLUTION 1 The keyboard sends a scan code of the key to the keyboard controller (Scan code for key pressed and key released is different) 2 The keyboard controller interprets the scan code and stores it in a buffer 3 The keyboard controller sends a hardware interrupt to the processor This is done by putting signal on “interrupt request line”: IRQ 1 4 The interrupt controller maps IRQ 1 into INT 9 5 An interrupt is a signal which tells the processor to stop what it was doing currently and do some special task 6 The processor invokes the “Interrupt handler” CPU fetches the address of “Interrupt Service Routine” (ISR) from “Interrupt Vector Table” maintained by the OS (Processor use the IRQ number for this) 7 The ISR reads the scan code from port 60h and decides whether to process it or pass the control to program for taking action CareerCup com pg 82 2 4 0
