XGE Silicon Stack Ethernet XGE4022‐PMC‐CC Data Sheet: Dual Port 1 Gbit/sec Silicon Stack Ethernet PMC (front copper) XGE4022 PMC The XGE4022 is the only true hardware based TCP/IP Offload Engine (TOE) available in a PMC form factor. The XGE product family differentiates itself from “non‐TOE” standard Gigabit Ethernet (as well as simple processor based TOE architectures) by delivering high sustained throughput, maximum host offload, ultra‐low latency, and rock solid deterministic behavior. The combination of the XGE hardware based TOE performance characteristics and it’s programmable architecture enables the use of Gigabit Ethernet as a high performance network fabric ‐ XGE4022-PMC-CC Features: one that offers the ubiquity, compatibility and simplicity of Silicon Stack Offload – full hardware offload standard Ethernet and the performance characteristics needed for Full line rate throughput high performance embedded systems. Very low host processor overhead Ultra low latency & rock solid determinism XGE Silicon Stack Advantage Zero Copy / Direct Data Placement (into app memory) Standard Gigabit Ethernet interfaces stifle the performance of Large send/receive offload even the most powerful CPUs when trying to move data at high UDP streaming support rates, let alone at full wire speed rates (1Gbps). This is due to 100% standard Ethernet compatibility the significant overhead caused by the TCP/IP protocol stack. Hardware BIT (Built in Test) Low power consumption The XGE series processes the complete protocol stack including Dual port ‐ copper RJ45 connectors Ethernet, TCP, UDP, IP, iSCSI, & RDMA in dedicated silicon and Front panel optical version also available frees all I/O protocol processing from the host system. By Rugged conduction cooled versions available leveraging the XGE product line, you can realize wire speed Comprehensive Software Library & driver support transfer rates, minimal host processor overhead, microsecond TOE Networking & iSCSI Storage Support latency and high determinism. Processor based TOE interfaces merely offload the host and are still plagued with high latency, Extensive Software Support & Capability poor reliability, and unpredictable behavior.

The XGE hardware Pipe Bypass for TCP / UDP TCP / UDP implements full TCP/IP offload in silicon. Full offload provides Special Frame ultra high performance, very low CPU loading, and perhaps Processing iSCSI RDMA iSCSI RDMA most important for real time systems, highly deterministic operation and consistently high data rates. And as can be seen in PCI DMA Engines the figure, there is no extra copying of data between host and PMC, and no time‐consuming interactions between the TOE PCI-X or PCIe Interface hardware and a software stack. Thus the latency, performance, and determinism characteristics that are critical in real‐time systems can be achieved. Figure 2: XGE Silicon Stack dual‐path architecture. Figure 1 compares the two PMC approaches from a software In addition, the XGE Silicon Stack TOE hardware has a unique point of view. This illustrates that, even though Processor based Dual Path architecture, shown in figure 2. The Dual Path “TOE” (figure 2, center) can be used to offload TCP/IP cycles architecture features two dedicated pipelined hardware data from a host processor, it solves only one of the problems of paths that implement full TCP/UDP/IP/RDMA/iSCSI offload in traditional Ethernet due to its continued reliance on the software silicon.

This engine has the ability to “tap in” to the The XGE Silicon Stack TOE approach (figure 1, right) eliminates hardware data paths to accommodate special frame processing the TCP/IP software stack, essentially connecting the TOE offload related to enhanced or specialized protocols. hardware directly into the sockets interface. Summary Traditional Ethernet Processor “TOE” XGE Silicon Stack TOE There are many advantages in using Gigabit Ethernet in data (incl. “Partial” TOE) Implementation Implementation intensive real‐time systems.

Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
