VMEbus Interface The XVME-654 uses the PCI local bus to interface to the VMEbus. The VMEbus interface supports full DMA to/from the VMEbus, integral FIFOs for posted writes, block mode transfers, and read-modify-write operations. The interface contains four master and four slave images that can be programmed in a variety of modes to allow the VMEbus to be mapped into the XVME-654 local memory. This makes it easy to configure VMEbus resources in protected and real-mode programs. Expansion Options PC/104 and PCI Mezzanine Card (PMC) expansion is available on the XVME-654 through the XVME-976 module. The XVME-976 offers PMC and PC/104 sites, allowing easy integration of PC/AT-compatible modules in your VMEbus system. Chapter 1 – Introduction 1-3 On-board Memory DRAM Memory The XVME-654 has one 72-pin SIMM memory site, providing up to 32 Mbytes of DRAM. The memory site can be populated by standard fast page mode memory or extended data out memory (EDO). EDO memory is designed to improve DRAM read performance. Using EDO memory improves the back-to-back burst timing to 2-2-2 from 3-3-3 of standard memory.
VMEbus接口XVME-654使用PCI本地总线与VMEbus连接。VMEbus接口支持从VMEbus到VMEbus的完全DMA，用于发布的写、块模式传输和读-修改-写操作的完整FIFOs。该接口包含四个主映像和四个从映像，可以以各种模式对它们进行编程，以允许将VMEbus映射到XVME-654本地内存。这使得在受保护的和真实模式的程序中配置VMEbus资源变得容易。扩张期权xme -654通过xme -976模块提供PC/104和PMC (PCI mezz Card)扩展。XVME-976提供PMC和PC/104站点，允许在VMEbus系统中轻松集成与PC/ at兼容的模块。
DRAM内存XVME-654有一个72针的SIMM内存站点，提供zui多32兆字节的DRAM。内存站点可以由标准的快速页面模式内存或扩展数据输出内存(EDO)填充。EDO存储器是为提高DRAM读性能而设计的。使用EDO内存将背靠背突发时间从标准内存的3-3-3改进为2-2-2。Flash BIOSXVME-654单板提供用于系统的Flash BIOS的位置ROM，视频ROM，和一个可选的以太网引导ROMKbyte x 8位或512 Kbyte x 8位设备。512kbyte Flash设备的内存映射如表1-1所示。
