XVME-654  PC-compatible VMEbus processor module 

The XVME-654 PC-compatible VMEbus processor module is the latest VME PC product from Xycom Automation, the pioneer and leader in VMEbus PC technology.
The new design integrates an AM5x86 processor along with a PCI-to-VMEbus interface, offering the latest in high-performance VMEbus technology.
At the core of the XVME-654 is the 133 MHz AM5x86 CPU. The CPU’s 16 K on-board, write-back cache minimizes the time the CPU spends waiting for data and instructions, accelerating business and multimedia applications. To further enhance the performance of its processor, the XVME-654 supports 4, 8, 16, and 32 MB of EDO DRAM.
Additional performance enhancements are provided through implementation of a Peripheral Component Interconnect (PCI) bus. The PCI bus is the fastest local bus designed for AT systems. It communicates with the high-speed video controller, enhanced IDE controller, and on-board Ethernet controller.

The PCI bus video controller–featuring a 64-bit graphics engine, with 24-bit RAMDAC for true color support– supports resolutions up to 1024 x 768 with 256 colors.
The controller also incorporates the latest Green PC monitor plug-and-play features for power savings. The video controller also offers hardware-assisted enhanced video playback for Indeo™, Cinepak™ , and MPEG-1.
The high-speed enhanced IDE (EIDE) controller supports programmed I/O modes 0-4 for IDE hard drives with capacities greater than 525 MB. EIDE and floppy controller signals are routed through the A and C rows of the P2 connector.
IDE hard drive and floppy drive capabilities are available through the connection of the XVME-977 single-slot VMEbus mass-storage module. A single ribbon cable is used to connect the XVME-654’s hard and floppy drive signals to the XVME-977. For applications that require mass storage outside of the VMEbus chassis, the XVME973 drive adapter module plugs onto the VMEbus P2 connector. This module provides industry- standard connections for IDE and floppy signals.
