- Systran Corp. announced it has expanded the number of interface boards that
- connect computers to its real-time, fiber-optic, replicated shared-memory
- network, SCRAMNet. Now, companies requiring true real-time (150 MBit/sec.)
- network performance can add MULTIBUS- and Encore's SelBUS-based system
- nodes. MULTIBUS-based computers, from companies such as Silicon Graphics,
- Concurrent Computer Corp., and Intel; and SelBUS-based computers from
- Encore Computer Corp. (formerly Gould CSD), can now be connected for
- real-time applications ranging from aircraft simulation to telemetry. The
- new boards bring the total number of SCRAMNet-supported backplane busses
- to eight.
-
- The SelBUS-based board, the SCRAMNet Model SE1000, is particularly useful
- for telemetry applications, where Encore computers have a large installed
- base and where real-time speeds are necessary for receiving and
- transmitting radio data for control purposes. The SCRAMNet Model Ml 100,
- based on MULTIBUS, allows systems integrators to connect Silicon Graphics
- series 2000 and 3000, Concurrent's 5000 line and Intel 310 AP or 320
- systems equipped with a 386 processor to SCRAMNet networks.
-
- Said W. Lynn Trainor, president of Systran, "SCRAMNet's forte is
- transferring data among different vendors' computers at the speed of
- light. With the introduction of the SelBUS and MULTIBUS boards, we've
- substantially increased the variety of networkable computers, furthering
- SCRAMNet's position as a standard in the realm of real-time applications,
- and allowing our customers to use whatever computer technology they need
- in their high-end data transfer applications."
-
- SCRAMNet Designed for Simplicity, Speed
-
- With SCRAMNet's replicated shared-memory design, all computer nodes on the
- network are equipped with identical computer-addressable memories. Every
- change to the replicated shared-memory at one node is immediately and
- automatically replicated in all nodes on the network in microseconds,
- causing all computers to appear to real-time applications as one large
- virtual multi-processor. Featuring fiber-optic technology, a sophisticated
- interrupt structure, data filtering and a programmable byte swapper, the
- SCRAMNet network avoids the limitations of physical shared-memory
- architecture and message-passing LANs to deliver true real-time speed,
- predictable performance, positive system control and with no software
- overhead.
-
- SelBUS--An Efficient Link to SCRAMNet
-
- The Model SE1000 provides a transparent, efficient link between the
- SCRAMNet network and SelBUS-based computer systems. Like all Systran
- boards, it features the SCRAMNet simplicity, where all data is replicated
- in SelBUS memory as it occurs, with no protocol conversions. Features
- include:
-
- ∙ Economical single board design that plugs into any SelBUS D.I. slot.
-
- ∙ Efficient memory scheme that eliminates additional memory costs while
- keeping SelBUS-resident caching devices current with network memory
- updates.
-
- ∙ Powerful interrupt on memory update capabilities.
-
- ∙ Status postings for generating error conditions and for generating
- externally accessible interrupt pulses per event.
-
- ∙ Flexible byte-swapping that uses two separate swapping matrices for
- network transmissions and network receptions.
-
- ∙ Effective data-integrity control.
-
- MULTIBUS Board Merges Reliability, Performance
-
- One of the most recent additions to the SCRAMNet network family, the Model
- M1100 features total compliance with the MULTIBUS I standard, efficient
- network writes, broad memory-mapping capabilities, and installation and
- verification software. It merges the performance provided by SCRAMNet with
- the proven reliability of MULTIBUS I-based systems for applications
- ranging from process control to aircraft simulation.
-
- Price and Availability
-
- Both the Model SE 1000 and the M1100 are available now, at prices per node
- ranging from $6,900 to $12,900, depending on configuration.
-
- An established research and development firm headquartered in Dayton, Ohio,
- Systran Corp. specializes in simulation, artificial intelligence and
- defense-related hardware/software research and development. The company's
- SCRAMNet network is the leading real-time network, with hundreds of nodes
- in use at aerospace, corporate and U.S. military installations. For more
