Included on the cPCI-MXS single-board computer is a high-availability controller that provides three control signals for each of the seven supported cPCI I/O slots (21 signals in total). The signals are used to detect the insertion of hot-swappable cPCI I/O boards, assert the board’s status, and control its startup. Also included on the board is the Intel 69000 APG graphics engine with 2 Mbytes of video memory and two 10Base-T/100Base-TX Intel Ethernet interfaces based on Intel’s 82559 chip. The board comes with a 333-MHz Pentium II processor, which includes 256 kbytes of Level 2 cache and supports up to 768 Mbytes of ECC SDRAM on three DIMMs.The PICMG-compliant board also integrates a SCSI 3 interface, on-board EIDE and hard-disk/floppy mezzanine module, PCI-to-PCI bridge, PMC mezzanine support, CompactFlash, and numerous I/O ports.
