DescriptionCritical IO XGE4022-PMC-CC Silicon Stack Ethernet Module
OverviewThe 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 - one that offers the ubiquity, compatibility and simplicity of standard Ethernet and the performance characteristics needed for high performance embedded systems.
XGE Silicon Stack AdvantageStandard Gigabit Ethernet interfaces stifle the performance of even the most powerful CPUs when trying to move data at high rates, let alone at full wire speed rates (1Gbps). This is due to the significant overhead caused by the TCP/IP protocol stack.The XGE series processes the complete protocol stack including Ethernet, TCP, UDP, IP, iSCSI, & RDMA in dedicated silicon and frees all I/O protocol processing from the host system. By leveraging the XGE product line, you can realize wire speed transfer rates, minimal host processor overhead, microsecond latency and high determinism. Processor based TOE interfaces merely offload the host and are still plagued with high latency, poor reliability, and unpredictable behavior.
Key FeaturesSilicon Stack Offload – full hardware offload Full line rate throughput Very low host processor overhead Ultra low latency & rock solid determinism Zero Copy / Direct Data Placement (into app memory) Large send/receive offload UDP streaming support 100% standard Ethernet compatibility Hardware BIT (Built in Test) Low power consumption Dual port ‐ copper RJ45 connectors Front panel optical version also available Rugged conduction cooled versions available Comprehensive Software Library & driver support TOE Networking & iSCSI Storage Support
Extensive Software Support & CapabilityCritical I/O supplies all the hardware, drivers, libraries, and protocol support youʹll need for rapid system development without wasting your time debugging drivers. All software has been highly optimized to deliver maximum performance, reliability, and capability.The XGE4022 hardware is accompanied by an extensive offering of software libraries and device drivers with support for embedded / real-time operating systems (VxWorks, RT Linux, and others) as well as mainstream OS platforms.In addition to standard OS level drivers, Critical I/O offers a comprehensive library that is ideally suited to applications that want to completely bypass the OS or that have no OS such as signal processing systems. These libraries are capable of running on a variety of embedded processor families, such as PowerPC, Intel/AMD x86, and DSPs.
