28.2 Introduction
The AND/OR/INVERT module (known simply as the AOI module) supports the
generation of a configurable number of EVENT signals. Each output EVENTn is a
configurable and/or/invert function of four associated AOI inputs: An, Bn, Cn, and Dn.
This module is designed to be integrated in conjuction with one or more inter-peripheral
crossbar switch (XBAR) modules. A crossbar switch is typically used to select the 4*n
AOI inputs from among available peripheral outputs and GPIO signals. The n EVENTn
outputs from the AOI module are typically used as additional inputs to a second crossbar
switch, adding to it the ability to connect to its outputs an arbitrary 4-input boolean
function of its other inputs.
The AOI controller is a slave peripheral module connecting event input indicators from a
variety of device modules and generating event output signals that can be routed to an
inter-peripheral crossbar switch or other peripherals. Its programming model is accessed
through the standard IPS (Sky Blue) slave interface. The module is designed to be very
configurable in terms of the functionality of its integrated AOI functions.
28.2.1 Overview
The AOI module supports a configurable number of event outputs, where each event
output represents a user-programmed combinational boolean function based on four event
inputs. The key features of this module include:
• Four dedicated inputs for each event output
• User-programmable combinational boolean function evaluation for each event output
• Memory-mapped device connected to a slave peripheral (IPS) bus
• Configurable number of event outputs
NOTE
The connections from the AOI module outputs to other
functions is SoC-specific.
