Introduction
The ACE IC is part of the ATLANTA chip set consist-
ing of four devices that provide a highly integrated,
innovative, and complete VLSI solution for imple-
menting the ATM layer core of an ATM switch system.
The chip set enables construction of high-perfor-
mance, feature-rich, and cost-effective ATM switches,
scalable over a wide range of switching capacities.
This document discusses the ACE device.
Features
I
Functions as a highly efficient, 5 Gbits/s, ATM
crossbar element.
— Allows construction of nonblocking, lossless,
and self-routing three-stage switch fabrics.
— Supports variable configurations for more com-
pact fabric design with higher port density. Each
ACE can be programmed to provide 1, 2, or 4
crossbars of different sizes.
I
Supports I/O port speeds up to 622 Mbits/s of ATM
traffic.
I
Incorporates independent clocking of input ports to
facilitate robust system designs by eliminating
clock trees and allowing for varied clock skews.
I
Uses differential clocking to provide noise immu-
nity.
I
Provides system diagnostic features, including
detection and reporting of the following error condi-
tions:
— Input port parity error.
— Loss of input port clock.
I
Supports a generic
16-bit microprocessor interface with interrupt.

Description
Figure 1 shows the architecture of an ATM switch
designed with the ATLANTA chip set. This document
summarizes ATLANTA switch fabrics and the
LUC4AC01 ATM Crossbar Element (ACE). The
ATLANTA ACE device provides the switching cross-
bar function for a three-stage ATM switch fabric. This
8 x 8 crossbar element is a key building block for
larger scalable three-stage switch fabrics (up to 40 x
40 OC-12 equivalent ports, 25 Gbits/s systems). The
ACE interfaces directly to the ATLANTA LUC4AS01
ATM Switch Element (ASX) device and is used for
linking switch elements. Nonblocking, lossless, and
self-routing switch fabrics can be constructed using
the ATLANTA chip set.
Each ACE is configurable to provide four crossbars of
a 2 x 2 configuration, two crossbars of up to a 4 x 4
configuration, or a single crossbar of up to an 8 x 8
configuration. It supports the novel internal backpres-
sure and routing algorithms of the companion ASX
device and provides fail-safe access to the output
ports.
The ACE also provides system diagnostic features.
Diagnostic reports include parity errors on inputs,
and loss of input port clock.
