Features

•

Also known as SMCS332SpW

•

3 identical bidirectional SpaceWire links allowing

– full duplex communication

– transmit rate from 1.25 up to 200 Mbit/s in each direction

Derived from the TSS901E-SMCS332 triple IEEE 1355 high speed controller

– Known anomalies of the TSS901E chip corrected

– Slightly different startup behavior

COmmunication Memory Interface (COMI)

– autonomous accesses to a communication memory

HOst Control Interface (HOCI)

– gives read/write accesses to the AT7911E configuration registers

– gives read/write accesses to the SpaceWire channels

Arbitration unit

– Allows two AT7911E to share one Dual Port RAM without external arbitration

Scalable databus width

– 8/16/32 bit width available

– allows flexible integration with any CPU type

Allows Little endian and Big endian configuration

1. Description

The AT7911E provides an interface between three SpaceWire links according to the

SpaceWire standard ECSS-E-50-12A specification and a data processing node consist-

ing of a Control Processing Unit and a communication data memory.

The AT7911E was designed by EADS Astrium in Germany under the name

'SMCS332SpW" for "Scalable Multi-channel Communication Subsystem for

SpaceWire". It is manufactured using the SEU hardened cell library from Atmel MG2RT

CMOS 0.5µm radiation tolerant sea of gates technology.

For any technical question relative to the functionality of the AT7911E please contact

Atmel technical support at

assp-applab.hotline@nto.atmel.com.

This document shall be read in conjunction with

EADS Astrium 'SMCS332SpW User

Manual'.

The complete user manual of the AT7911E also called SMCS332SpW is avail-

able at

www.atmel.com.

The AT7911E provides hardware supported execution of the major parts of the interpro-

cessor communication protocol, particularly:

•

Transfer of data between two nodes of a multi-processor system with minimal host

CPU intervention

Execution of simple commands to provide basic features for system control

functions

Provision of fault tolerant features.

Target applications are heterogeneous multi-processor systems supported by scalable

interfaces including the little/big endian byte swapping. The AT7911E connects modules

with different processors (e.g. TSC695F, AT697E and others). Any kind of network

topology could be realized through the high speed point-to-point SpaceWire links (see

the section ‘Applications’).

It can also be used for modules without any communication features such as special

image compression chips, some signal processors, application specific programmable

logic or mass memory.

The AT7911E may also be used in single board systems where standardised high

speed interfaces are needed and systems containing "non-intelligent" modules such as

A/D-converter or sensor interfaces which can be assembled with the AT7911E thanks to

the "control by link" feature.
