Trenton's SLT system host board (SHB) features two, dual-core processors that together provide four execution cores per SLT. The SLT's two dual-core Intel® Xeon® LV processors deliver superior processing capability and system performance using about half as much power as compared to previous generations of low voltage Intel Xeon processors. The SLT is a server-class PICMG®1.3 SHB that supports one x4 and two x8 PCI Express links to a PICMG 1.3 backplane. An additional x4 PCIe link to a backplane is available using Trenton's IOB31 expansion module. These links support PCI Express, PCI and PCI-X option cards on a PICMG 1.3 server-class backplane.
