Our New Look. Look for it.
he integration GE Fanuc Embedded Systems, Condor Engineering and GE FANUC is a giant step toward our long-term vision of creating a different and better kind of embedded company. Behind the scenes there has been a flurry of activity aimed at melding these three organizations into one unified new company. Perhaps the first and most visible results of that work is our new logo and the new look for newsletters, websites, advertising and other marketing materials.
In line with the GE corporate identity, and the overall theme of “Imagination at work,” we have created a simple, clean and approachable format that we believe will make it easy for customers and partners to find the information they need. GE has made a major commitment to the embedded market place, and we hope our new design look reflects this exciting new company.
Introducing GE Fanuc Embedded Systems.
Some things, however, have not changed. You can still expect superior quality of design and the added value of a partnership with GE. You can still depend on a strong global infrastructure of development, service and support; advanced supply chain management and a history of manufacturing leadership; plus our long-standing commitment to Six Sigma quality in all we do. With 30 years of global service to the embedded systems industry, we will continue to offer the experience, stability, resources, and strength you have come to rely on.

All channels are multi-function, supporting simultaneous operation of a Bus Controller (BC), (1 or 31) Remote Terminals (RT), and Bus Monitoring (BM). An IRIG-B option is available.
I/O connections are available from either the front bezel or via the P14 connector. Also included with the EPMC-1553 is CORE-API, a flexible, easy-to-port API provided in source code. Board support packages for Windows XP, 2000, Me, NT, 98, 95, and VxWorks are provided.>
10Mbit MIL-STD-1553 PMCP-10SF Brings Higher Performance in Small PMC Package
The P-10SF is the first PMC module on the market to offer 10Mbit data throughput for MIL-STD-1553 over RS-485. Available with 1 or 2 dual-redundant, fully compliant 1553/1760 interface channels with 8 discrete lines usable for RT address lines and BC triggers, the P-10SF offers BC or single RT or Bus Monitor operational modes. Advanced features include full error detection, programmable IGT and RT response times, BC scheduling, and “one-shot” operations.

Intelligent Network Processor-Based AdvancedMC™Multi Service Telum™ 1204-O3 AdvancedMC is designed for high availability edge access applications
The Telum 1204-O3 is essentially a gateway in an AdvancedMC module format specifically designed to facilitate the migration from legacy networks to IP-based networks. This product is flexible and software configurable, and includes features such as:
VME Intel® Pentium® M Processor-based Single Board Computer6U VMEbus V5D demonstrates commitment to the life-cycle of V5 Line
The V5D SBC is the next generation in our popular V5 product line that started with the V5A. The V5D continues to keep this SBC line updated with the latest technology while maintaining backwards compatibility to the existing product lines to ensure program longevity for our customers.
The V5D includes the Intel® 855GME Chipset which provides a 400 MHz Front Side Bus interface and a memory controller with a 64-bit 266 MHz memory interface that services up to 1 GB of DDR SDRAM. It also includes an internal SVGA video controller with 2D and 3D graphics engines and a 350 MHz 24-bit RAMDAC that can drive an analog CRT monitor at resolutions up to 1600 x 1200.
6U CPCI PowerPC® Processor-based Single Board Computer6U PICMG® 2.16 C2K SBC delivers I/O flexibility and rugged options
The C2K uses the 1 GHz MPC7447A or 1.4 GHz MPC7448 Freescale™ processor and extensive I/O ports for improved performance and flexible, rugged functionality. It integrates the Marvell® MV64460 System Controller (Discovery III) Bridge chip, which includes a high speed DDR333 SDRAM controller with 167MHz interface that can service memory up to 1GBytes. For increased I/O expansion, the C2K hosts two 64-bit IEEE1386.1 PMC sites, and the PLX PCI 6254 CompactPCI® Backplane Bridge allows the C2K to operate as a system controller or peripheral processor card.
AFDX - Swift and Sure FootedBy John Bruno
The AFDX Interconnect is a Full Duplex, switched Ethernet interface, not ARINC 429 or MIL-STD-1553. Original Ethernet is Half Duplex, and uses the Carrier-Sense Multiple Access/Collision Detection (CSMA/CD) media access protocol and repeater hubs. The issue with Half Duplex Ethernet is that with multiple hosts connected to the same communication medium, and with no central coordination, it is possible for two hosts to transmit “simultaneously” such that their transmissions “collide.”
It is theoretically possible for Ethernet packets to repeatedly collide. In fact, there is a chance for an infinite chain of collisions, in which case the packet would never be successfully transmitted. In Half Duplex mode very large transmission delays are possible, and this situation is not be acceptable in an avionics data network.
Full Duplex, Switched Architecture overcomes the issue of collisions on bus-based Ethernet. As shown in Figure 1, each Avionics Subsystem—autopilot, heads-up display, etc. — is directly connected to a Switch over a Full Duplex link that comprises two twisted pairs — one pair for transmit (Tx) and one pair for receive (Rx).
The Rx and Tx buffers can store numerous packets in FIFO order. The role of the CPU is to move packets from the incoming Rx buffers to the outgoing Tx buffers. It examines each arriving packet to determine its destination address and sends it to the correct Tx buffer(s). The packet is copied into the Tx buffer(s) via the Memory Bus, and transmitted in FIFO order to the selected Avionic Subsystem or to another switch.
With this Full Duplex switch architecture, the contention encountered with Ethernet is eliminated, simply because the architecture completely eliminates collisions. In actual practice, two totally redundant switch architectures are employed.
Theoretically, an Rx or Tx buffer could overflow, but if buffer requirements are planned correctly in the original design, this cannot happen. With AFDX, a message may not get out immediately, but it will be not be delayed for more than a given time interval, say no more than 400 microseconds.
GE Fanuc Embedded Systems has been involved in avionics protocol support for decades, and we currently offer a wide selection of high performance, proven AFDX /ARINC 664 products, with either hardware or software-based AFDX engines. Because we offer both hardware and software-based AFDX implementations, we give you the option of choosing the AFDX that’s right for your application.
We supply high performance AFDX development, test and simulation tools for PCI, CompactPCI and PMC formats, in addition to conduction-cooled VME End Systems. Our flexible single or dual channel hardware and powerful software development tools at the frame and End System levels have been chosen to provide support for both the Boeing 787 and Airbus A380.
BusTools/AFDX, our Windows XP/2000-based GUI tool for traffic monitoring, analysis and generation, makes it easy to view, log, analyze and create AFDX network traffic at the Adapter, End System, Virtual Link or Port levels. With our wide range of product offerings, GE Fanuc Embedded Systems has become the AFDX supplier of choice.> To view AFDX Tutorial
MicroTCA™ Ratification AnnouncedBy Jeff Marden
MicroTCA™, the most highly anticipated embedded specifications to be released in a decade, has been unanimously ratified, and is about to be published. This is very exciting news for those of us on the subcommittees and working groups who have labored long and hard to get the details hammered out.
More importantly, this is a significant breakthrough for the entire embedded computing community. MicroTCA takes what has been learned from AdvancedTCA® and delivers it in a small and yet incredibly potent package. Because of this, I believe MicroTCA will spread from communications applications into the rest of the embedded market space.
There have been a lot of rumors about exactly what was included in the final specification, and there may be a significant amount of confusion. So in the next few paragraphs I would like to give a short, birds-eye view of what I consider to be the most significant features of MicroTCA.
What is MicroTCA?

Full AdvancedMC Module Support
Now the fun begins
From a purely technological point of view, MicroTCA certainly looks like a winner but it will have to pass a number of tests before we declare it a success. Will it achieve high enough production levels to meet its pricing goals? Will a strong vendor base develop? Will it find acceptance outside the telecom market? Only time will tell, and now that the specification is ratified, the clock is ticking.
