physical interfaces. Multiple SCSI controllers can be
supported by a single SSC200 with the addition of
external DMA control signal routing logic.
For lower cost applications, a simple SCSI bus
transceiver device utilizing the 28 available general-
purpose I/O signals may replace the external SCSI
controller.
Architecture
System Level Integration (SLI) techniques were
used to create a complete system on a chip. The
SSC200 integrates a RISC embedded processor
and additional DMA, memory and controller
functionality.
The SSC200 includes three, I

C serial interface bus
master controllers. These controllers may be used
to interface to off-the-shelf instrumentation and
control devices commonly used in environmental
monitoring and management applications such as
Vitesse's SSC050/055 Backplane Controller.
The SSC200 requires off chip memory for firmware
code storage. Most applications will use flash
memory devices for non-volatile storage. Static
RAM may be added for higher performance
applications. The SSC200 has four external chip
selects each with a one-megabyte address range.
Two RS-232 serial ports provide assist firmware
debug. One port is dedicated to in circuit emulation
for the embedded processor. The second port
implements a XMODEM connection for additional
debug
and
firmware
downloads are also supported via ESI and SCSI
buses.
download.
Firmware
Software
The software designed to execute on the SSC200
determines the characteristics of the overall
enclosure management solution. Most enclosure
management applications will be unique to a
customer's individual product. The SSC200
firmware architecture uses a Personality Module with
captures the unique functionality required by a
particular application. Vitesse provides a Software
Development Kit (SDK) to customers to assist their
development of their Personality Module.
The SDK includes software to implement an ESI and
a parallel SCSI transport for a SAF-TE or SES
diagnostic environment. In addition, the SDK also
includes a System Services module with provides
APIs to the peripheral functionality (interrupts, timers
etc.) in the SSC200.
The SSC200 shares a similar hardware and
firmware architecture as Vitesse’s SSC100 for
dedicated port FC-AL SES. This allows system
designers to leverage enclosure management
strategies and implementations across parallel
SCSI, ESI and dedicated port FC-AL storage
solutions.
