About this document

I/O Basics and Interrupts in LC-3 by Elad Talic is a document available to read on EtoBox.

This lecture discusses input, output, and trap instructions in computers. It covers I/O basics including keyboard input, monitor output, interrupt-driven I/O, and DMA. It also explains polling and interrupt-driven synchronization between the CPU and I/O devices. Trap instructions allow privileged tasks to be isolated from user programs. The LC-3 uses memory-mapped I/O and a trap vector table to implement I/O and privileged instructions.
