Next-generation serial data link provides the flexibility of IEEE 1394
with three times the performance
DETROIT, March 8 /PRNewswire/ -- Opal-RT Technologies Inc.
(http://www.opal-rt.com ), the world leader in distributed real-time simulation on
PC-based platforms, today introduced SignalWire(TM) -- an FPGA-driven real-
time data transfer technology that meets the performance demands of
engineering simulation applications, particularly those that require sub 10
microsecond time steps over a distributed network of real-time processors.
A standard feature of the Opal-RT FPGA product family (See press release
"Opal-RT Technologies Launches New Family of FPGA I/O Products" dated Monday,
March 8, 2004), SignalWire is an enhanced inter-processor communication
technology that has been developed for high-performance real-time applications
using RT-LAB(TM) Engineering Simulators.
The introduction of SignalWire represents a next logical step for Opal-RT.
The company has been a leader in the development of PC-based real-time
simulation technologies that utilize IEEE 1394 since launching RT-LAB in 1997.
"As data transfer demands grow, the use of off-the-shelf real-time links
for RT-LAB target clusters is becoming less and less feasible," said Paul
Goossens, Vice President of Marketing at Opal-RT Technologies. "As part of
our FPGA product strategy, Opal-RT has developed SignalWire, providing RT-LAB
users with a high speed technology that is complementary to IEEE 1394 but with
increased performance."
While IEEE 1394 interprocessor communications provides very rapid data
transfer from one processor to another, it was not designed for the type of
data transfer required for distributed real-time simulation. One disadvantage
is the latency overhead of approximately 2 microseconds, which becomes highly
significant in simulations that require cycle times below 50 microseconds.
SignalWire overcomes the latency issues of IEEE 1394 and provides a three-
fold increase in data transmission speed -- up to 1.25 Gbits/s full duplex.
By using SignalWire, simulation sampling time can be increased from 20 kHz
to 100 kHz and beyond. This is particularly important for next generation
multi-ECU Hardware in the Loop (HIL) systems as well as for high-performance
HIL simulators' need to simulate electric hybrid vehicles.
SignalWire is tightly integrated with the Opal-RT's RT-LAB platform
through the company's family of FPGA IO products. This fits with the
company's objective of developing a wide range of remote, intelligent data I/O
modules that operate separate from the main CPU but communicate at high speed
with it. This removes the traditional limitation on the number of I/O devices
installed on a PCI bus and alleviates problems with remote sensors in
electrically noisy environments by carrying out the conversion locally before
sending the data over the SignalWire link to Target PCs.
Pricing & Availability
Opal-RT FPGA products are now available directly from Opal-RT Technologies
and the company's worldwide network of distributors. Special pricing is
available where systems are to be used in academic research projects.

About RT-LAB
RT-LAB is the real-time technology that revolutionizes the way model-based
design is performed within the engineering organization. Through its
openness, RT-LAB has the flexibility to be applied to any simulation and
control problem, and scalability to provide a low-risk entry point for any
application, allowing the developer to add computation power where and when
needed -- whether to dramatically speed up simulations or for real-time
hardware-in-the-loop applications.
