VC-121 single-board computer (SBC) is a high-speed 1.8-GHz Intel® Pentium® M processor-based 6U VME SBC that includes a main board and an expansion board. Numerous I/O options are built into the board with additional I/O available through the expansion mezzanine PMC sites.
VLA-150 is a 6U processor module designed for high-performance applications. The UltraSPARC®IIi+ processor's integrated architecture has a built-in PCI bridge and SDRAM memory controller that connect the processor to the rest of the system. Flexible I/O and board-to-board communications to other systems are accomplished using additional interfaces, including a PMC slot, a Gigabit Ethernet controller, a device bus interface, and a PCI-to-VMEbus bridge.
