SHB Express or PICMG 1.3 is a new industry standard that defines scalable, high speed and large bandwidth PCI Express™ links between the system host board, (i.e. single board computer) and an SHB Express backplane.
Why SHB Express? Today's processors and I/O devices are placing an ever increasing demands on todays PCI/PCI-X parallel bus architecture. This situation will become more acute as processor speeds continue to inrease and I/O devices demand greater bandwidth. Industrial computing applications are demanding more performance from the hardware platforms, and SHB Express solves these bandwidth issues while enhancing the organization's return on investment (ROI) in PCI/PCI-X software and hardware.
The high speed PCI Express serial links between the system host board and the backplane in an SHB Express system eliminates data bottlenecks caused by parallel bus architectures. System design costs are reduced because of the simplified power management features of SHB Express. System Value and ROI are maximized because of SHB Express' ability to provide seamless support of the PCI addressing model. This means that SHB Express systems can function with the operating systems, application software, device drivers and option cards used in previous PCI/PCI-X system designs.
Dual Processor SHB's
SLT
The SLT is a server-class PICMG® 1.3 SHB featuring two Dual-Core Intel® Xeon® processors. This system host board provides four processor execution cores operating at about half the wattage of previous generation CPUs. The board has a low-profile passive heat sink and uses the Intel E7520 chipset.
NLT
The NLT system host board (SHB) or single board computer (SBC) is a server-class SHB Express® (PICMG® 1.3) computer board that provides PCI Express interconnects between the SHB and backplane. The board features dual Intel® Xeon® processors and the Intel® E7520 chipset.
Single Processor SHB's
TQ9
The TQ9 is a graphics-class SHB with on-board audio, a dual-core or quad-core processor option, up to 8GB of system memory, built-in RAID support and many other advanced I/O capabilities. Direct support for x16, x8, x4 and x1PCI Express™ links to a PICMG® 1.3 backplane as well as a 32-bit/33MHz PCI interface are featured on the TQ9 single board computer.
TML
The TML is a graphics-class SHB with similar features to the T4L system host board. The SHB supports high-end PCI Express or ADD2 video and graphic cards as well as PCI-X and PCI option cards. The TML pairs the Intel® 945G chipset and the Intel® ICH7R I/O controller with processor options that include the Intel® Core® Duo, Intel Core® Solo and the Intel® Celeron® M.
SLI
The SLI is a single processor version of the SLT and offers two processor execution cores per board via a single, long-life Dual-Core Intel® Xeon® Processor LV 2.0GHz.
T4L
The T4L is a graphics-class SHB with direct support for x16, x4 and x1 PCI Express™ links to a PICMG® 1.3 backplane. The SHB supports high-end PCI Express or ADD2 video and graphic cards as well as PCI-X and PCI option cards. The T4L features the Intel® 945G chipset with the Intel® ICH7R I/O controller. Processor options include the Intel® Pentium® 4, the Intel® Pentium® D and the Intel® Celeron® D.
NLI
Like the NLT, the NLI is a server-class system host board (SHB) or single board computer (SBC) that supports the SHB Express™ (PICMG® 1.3) specification. The NLT supports PCI Express interconnects between the SHB and backplane. The board features a single Intel® Xeon™ processor and the Intel E7520 chipset.
Option Cards
IOB31
This optional board plugs into connector P20 on either the NLT or NLI system host board (SHB) to provide I/O and PCI Express expansion capability on backplanes like the BPX3/14. On board IOB31 connectors provide two serial ports, a parallel port, PS/2 mouse and keyboard connections and a floppy port.
IOB30
This optional board plugs into connector P20 on either the NLT or NLI system host board (SHB) to provide I/O expansion capability for two serial ports, a parallel port, PS/2 mouse and keyboard connections and a floppy port.
