OPB PS/2 Controller (Dual)

This module is an On-Chip Peripheral Bus (OPB) slave device that is designed to control

two PS/2 devices such as a mouse and keyboard. It utilizes the Xilinx Intellectual Property

InterFace (IPIF) to simplify its design. The OPB PS/2 Controller module generates

interrupts upon various transmit or receive conditions. This document assumes the user is

already familiar with the PS/2 interface protocol. Additional information about PS/2 ports

and peripherals is widely available on the Internet or through a computer hardware

reference manual.
