telecommunications platforms. In addition, the 4532
allows direct connection to SONET or SDH facilities,
eliminating the need for additional line termination
equipment. Featuring a powerful MPC8260A
on-board RISC processor, high performance
architecture, and advanced ATM functionality, the
4532 is the industry’s best choice for a 155 Mbps

4532 Software
Reduce time-to-market with robust software development tools
Interphase offers a robust suite of software development tools to help shorten the learning curve and design cycle for integration projects based on the 4532 communications controller. Interphase provides three types of development tools, each tailored to the needs of
different intergrations. The Basic Board Support Package (BBSP) allows software developers to write software applications that run
on a specifi c operating system embedded on the MPC8260A CPU. The Board Development Kit (BDK) facilitates development of device
drivers, embedded protocol fi rmware and applications for the 4532 hardware module. The iWARE
developers a set of Interphase-developed fi rmware protocol stacks, accessible via APIs provided by Interphase.

Software Development Suite offers
Summary
• Board Development Kit (BDK)
• VxWorks® Basic Board Support Package (BSP)
• VxWorks Software Development Suite (SDS)
Board Development Kit
The 4532 BDK is specifi c to the 4532 hardware, but it is not tied to
a particular operating system environment. The kit contains the
following main components:
• Setup Utility: Allows the user to modify the content of the
various programmable elements of the board, especially the
Flash EEPROM memory.
• Boot Firmware: Provides power-on self test, power-on boot
sequence, built-in self test (described below), confi guration
capability via a command line interface, and boot fi rmware
source fi les as an example of how to program the card.
• Board Installation and Maintenance Manual: Provides
procedures for installing and maintaining the module.
• Hardware Reference Manual: Provides information for
developing embedded software and/or host drivers for the
module.
• Interactive Built-in Self Test Utility and Monitor Manual: Allows
management of the card such as, reset/run action, memory
and register dump, memory and DMA tests, line parameter
manipulation, and more. Manual provides high-level information
for using the boot fi rmware.
Basic Board Support Package
The 4532 Basic Board Support Package (BBSP) consists of
documentation compiled as a Board Support Guide for VxWorks.
This document provides valuable information on how to confi gure
and install VxWorks on the 4532. Once the BSP is installed, the 4532
can be connected to an Ethernet network and development can be
done directly from the particular RTOS development environment,
such as Tornado. The 4532 BSP also includes the fi les required to
make an RTOS run embedded on the 4532 CPU. The standard BSP
is free of charge, but must be ordered separately.
The package provides source fi les for:
• Interrupt controller
• Flash memory management
• True Flash File System (TFFS) support
• TTY driver
• Ethernet driver (broadcast and multicast support)
• Timestamp driver
iSPAN 4532 PMC ATM over OC-3c/STM-1 Communications Controller
• Auxiliary timer support
Also available via the Interphase Professional Services Group:
• Framer device driver framework
• AAL1, 2 and 5 driver framework
• PCI driver framework
iWARE® Software Development Suite
The 4532 iWARE Software Development Suite (SDS) reduces
software development time and facilitates faster time to market by
supplying embedded protocol support for ATM, base drivers for a
selected operating system, confi guration and diagnostic utilities,
and sample programs. The 4532 is offered with an iWARE Software
Development Suite for the following operating systems:
• Linux
• For other operating systems, please call for availability
The iWARE Software Development Suite enables easy integration
with tools and diagnostics to simplify development. The SDS also
provides Interphase’s own lower layer stacks for various network
protocols (contact your Interphase representative for specifi c
protocols). Complete, pre-integrated stacks using Interphase
lower layers and third party upper layers are also available.
The iWARE Software Development Suite consists of software
programs and utilities running on the host CPU and embedded
software (“fi rmware”) which runs on the on-board 8260A
processor. Software elements are separated into four modules:
• The base drivers for each supported Operating System
(executed by the host processor)
• The confi guration and diagnostic utilities
• Sample programs
• The embedded fi rmware executed by the MPC8260A on the 4532
board
These modules interact with each other through well-defi ned and
documented interfaces. A common iWARE WAN API is defi ned
at the interface between the embedded fi rmware and the various
drivers. A complete documentation set is also provided describing
Interphase’s iWARE WAN API (Wide Area Network Application
Programmer’s Interface), the Base Driver’s API, sample programs,
and tool guides.
Custom Development
Custom software development, integration, and consulting services
are also available via the Interphase Professional Services Group.
With over 150 man years of development experienced amassed,
the professional services team offers everything from completely
custom development to merely customizing standard Interphase
products to meet your specifi c needs.

4532 Hardware
Powerful Features for Next-Generation Telecom Applications
4532 Architecture
The iSPAN 4532 PMC ATM Over OC3/STM-1 Communications
Controller is a member of the Interphase line of MPC8260A-based
controllers for carrier-class telecommunications environments.
The software selectable interface for SONET OC-3c or SDH STM-1
makes the 4532 a universal interface module and enables maximum
fl exibility to support multiple international standard variants with
just one board.
The 64-bit, 66 MHz 60x data bus connects the core RISC CPU to
the 64-bit wide SDRAM memory and the local side of the Tundra
PowerSpan PCI bridge. I/O transfers across the bridge to the PCI
bus are executed at 32-bits, 33 MHz or 66 MHz. Also connected to
the 60x data bus is an 16-bit 8 MB downloadable Flash memory (4
MB of 8-bit Flash on original 4532 models) that can be used to store
boot code and operational fi rmware.
The MPC8260A CPM co-processor interfaces to the SONET/
SDH ATM framer via a master UTOPIA bus interface, which in
turn connects to the optical transceiver that connects to the
transmission line. The MPC8260A CPM performs all ATM layer
functions, including ATM layer, and up to the Common Part
Convergence Sublayer (CPCS) AAL functionality. The CPM has
separate and unimpeded access to a second block of 8 MB of
SDRAM memory, which can be used for storing virtual connection
lookup tables and traffi c descriptors.
A second slave-mode UTOPIA interface from the 8260A CPM
coprocessor is available to a carrier card via the PMC P3 connector,
and can carry ATM traffi c to and from the carrier card. In this
mode, the 4532 can be used as the front-end to an ATM switch as a
peripheral I/O card. Furthermore, the 8260A core RISC CPU can be
disabled, in which case the 4532 utilizes the CPM co-processor and
the ATM framer only to act as the physical I/O interconnect to an
ATM link.
