USB HOST Controller To Processor

Processor(I am god)

USB Host Controller(I am the boss)

Hey dude!!! there is an

interrupt for you(INT)

Let me finish the current work, will get back to you

later(INTA)

Okay put the interrupt

number on the bus

(INTA)

Here is the interrupt number

Possible ways to communicate

Apple Desktop Bus (ADB)RS-232Bus Mouse Interface (BMI)PS/2USB

PS/2: Personal System/2

Features:◦Synchronous◦Simple & Cheap◦No plug and play (hot plugging)

Interrupt Handling Data Structures

Processor to Browser

Interrupt vector table implemented using the data structure IDT (interrupt descriptor table

Device driver routine called.X server registers callback with Composite

window manager(wayland display server is used now)

X server gives control to active window and pass it the the message as well.
