 INTERRUPT REQUEST Definition
We define INTERRUPT REQUEST |
INTERRUPT REQUEST - A means for devices to request time from the processor to do their jobs. For instance, every time you hit a key on your keyboard an interrupt is generated on the keyboard IRQ. This is mainly only a concern for PC users, and IRQs were the bane of existence for many computer builders when ISA cards were more popular. Nowadays IRQ problems can still be a hassle, as you only get 16 of them and many are used already, but devices share IRQs more intelligently. |
