StreamBladeTM Architecture
Time to deliver today…
• Integrating multi-vendor products is time consuming
• Getting board support packages (BSPs) and development
environments set up is time consuming
• Installing and learning to use new tools is time consuming
• Debugging embedded applications is time consuming
8
StreamBladeTM Architecture
How do we scale our prototype system today?
• Add DRS Receivers?
• Add Mercury QUAD G4 boards?
• How many slots are in the chassis?
• How many chassis do we need?
• Will the backplane width restrict scalability?
9
StreamBladeTM Architecture
What if we want to see COTS vendor source code today?
• Good Luck…

StreamBladeTM Architecture
Concept
• StreamBladeTM Architecture adopted these principles:

–
–
–
–
–
Keep It Simple Stupid (KISS)
Use proven technology
Simplify connectivity
Simplify development
Use plug and play components
Keep an eye on cost
11
StreamBladeTM Architecture
Remember “breadboard” prototypes?
•
•
•
•
•
•
KISS
Proven technology
Simple connections
Easy to build
Plug and play
Cheap
12
StreamBladeTM Architecture
It is not as easy to “breadboard” prototype today…
• Today functional blocks are implemented in hardware, software, and
firmware
• Today the signals are higher frequency and more complicated
• Today the interfaces between functional blocks are higher speed
and more complicated
13
StreamBladeTM Architecture
Technology
• StreamBladeTM Architecture leverages existing, proven, inexpensive,
easy to use, scaleable, standards based technologies such as:
–
–
–
–
TCP/IP
Ethernet
FPGA
DSP
14
StreamBladeTM Architecture
TCP/IP
• Sockets based programming is well understood today
• Today the real-time processing can be pushed into DSP or FPGA
material
• Inexpensive operating systems, such as Linux, can be used in
embedded applications as configuration and control fabric
• TCP Offload Engines (TOEs) and protocols such as RDMA reduce
host processor cycles required to transfer data
15
StreamBladeTM Architecture
Ethernet
• Real-time processing nodes can be connected by 10/100/1000
Ethernet and 10 Gig-E is just around the corner
• Ethernet will work over twisted pair or fiber interfaces
• Ethernet is inexpensive, available, and standards based
• Today just about every type of computer or peripheral has a
Ethernet interface
• Today network switches provide real-time processing nodes with
non-blocking bandwidth connectivity
16
StreamBladeTM Architecture
FPGA & DSP
• FPGA technology has advanced and is providing multi-million gate
solutions
• FPGA technology is less expensive today
• Today FPGA manufacturers are providing Ethernet building blocks
and DSPs as hard cores in FPGA products
• Today many companies such as RFEL develop FPGA cores to
perform signal processing functions such as FFTs, filters, and digital
drop receivers (DDRs) at reasonable cost

StreamBladeTM Architecture
SOE Technology
The Stream Offload Engine (SOETM) is at the core of the
Embedded Systems Design, Inc. (ESD) StreamBladeTM family of
single board computers. StreamBladeTM single board computers
utilize ESD’s SOETM technology to provide zero-copy, full TCP/IP
offload, and 10/100/1000 Ethernet connectivity between the
application FPGAs and external real-time streaming data processing
nodes. ESD’s SOETM technology acts to decouple real-time
streaming data source and sink processing nodes allowing real-time
processing jitter to occur without data loss. When necessary, it is
possible to run data distribution service (DDS) source/sink agent
software on the PPC405 inside the SOETM.

Foundation Tools:
ESD StreamBedTM firmware is provided with each board. The
StreamBedTM firmware CD includes a Bootloader, Flash Burner, and
StreamBladeTM Diagnostics. Developers may download and run applications,
test StreamBladeTM hardware, and burn images to Flash via Ethernet, serial
port, or the PCI bus.
ESD StreamBedTM software is provided with each board. The
StreamBedTM software CD includes executable Linux and Windows device
drivers. The drivers provide the host computer, via the PCI bus, the ability to
control and receive status from one or more StreamBladeTM single board
computers. ESD StreamBedTM software comes complete with device driver
documentation, driver source code, pre-compiled driver images, and driver
build files for StreamBladeTM single board computers. Contact ESD for more
information:

Application Development:
A Xilinx Virtex-4 FX60 BSP is available from ESD. The BSP
development CD comes complete with documentation, source code, presynthesized designs, and project files. Sample applications demonstrate how
to interface user configurable I/O from a 40 Pin ATA connector with a Stream
Offload Engine (SOE).
Xilinx development tools and the Xilinx Embedded Development Kit
(EDK) are available from Xilinx. Contact Xilinx for more information:
