MVME5110-2261 VMEbus单板计算机

艾默生网络电源MVME5100系列是艾默生PowerPlus II VME架构系列的旗舰产品，可在单个VMEbus插槽中实现超级计算水平的性能。基于艾默生设计的集成PCI桥式内存控制器ASIC, PowerPlus II将内存性能提升到新的水平，具有582MB/s的内存读取带宽和640MB/s的突发写入带宽。
MVME5100系列采用PowerPlus II架构来支持264MB/s的全PCI吞吐量，而不会耗尽处理器的内存。MVME5100旨在满足oem服务于国防和航空航天，工业自动化和医疗细分市场的需求

从历史上看，艾默生在其PowerPC®Architecture VME产品组合中提供了两个轨道。第一个轨道(包括MVME2600/2700)提供典型的单板计算机I/O功能，包括以太网，SCSI，多个串行端口，并行端口和单个PMC插槽。板载I/O路由到P2，并通过艾默生MVME761或MVME712M过渡板提供给用户。第二个轨道(包括MVME2300/2400)提供有限的板载I/O(以太网和通过前面板的单个串行端口)，但提供双PMC插槽，可实现最大的用户I/O定制。
MVME5100融合了两种轨道的最佳功能，使OEM能够使用相同的基础平台支持不同的I/O要求，简化了零件号维护，技术专长要求和节省。

IPMC761和IPMC712是可选的PMC附加模块，可向后兼容上一代艾默生产品(如
MVME2600和MVME2700)使用MVME761或MVME712M过渡板。IPMC模块提供以下后置I/O支持:
一个单端超宽SCSI端口
1个并口
四个串口(2或3个异步和1或2个同步/异步，取决于模块)
通过这种PMC卡配置，内存夹层、一个PMC插槽和PMCspan仍然可用，为OEM产品定制提供支持。

The Emerson Network Power MVME5100 series is the flagship of the Emerson PowerPlus II VME Architecture line, enabling supercomputing levels of performance in a single VMEbus slot. Based on an integrated PCI bridge-memory controller ASIC designed by Emerson, PowerPlus II takes memory performance to new levels with 582MB/s memory read bandwidth and 640MB/s burst write bandwidth.
The MVME5100 series utilizes the PowerPlus II Architecture to support full PCI throughput of 264MB/s without starving the processor from its memory. The MVME5100 is designed to meet the needs of OEMs servicing the defense and aerospace, industrial automation and medical market segments

Historically, Emerson has offered two tracks in its PowerPC® Architecture VME portfolio. The first track (which includes the MVME2600/2700) provides typical single-board computer I/O features including Ethernet, SCSI, multiple serial ports, a parallel port and a single PMC slot. The on-board I/O is routed to P2 and made available to the user via Emerson MVME761 or MVME712M transition boards. The second track (which includes the MVME2300/2400) offers limited on-board I/O (Ethernet and a single serial port both via the front panel) but provides dual PMC slots enabling maximum user I/O customization.
The MVME5100 merges the best features of both tracks enabling the OEM to support varying I/O requirements with the same base platform, simplifying part number maintenance, technical expertise requirements and sparing.

The IPMC761 and IPMC712 are optional add-on PMC modules that provide backward compatibility with previous-generation Emerson products (such as
MVME2600 and MVME2700) using the MVME761 or MVME712M transition board. IPMC modules provide rear I/O support for the following:
ƒ One single-ended Ultra Wide SCSI port
ƒ One parallel port
ƒ Four serial ports (2 or 3 async and 1 or 2 sync/async, depending on module)
With this PMC card configuration, the memory mezzanine, one PMC slot and the PMCspan are still available, providing support for OEM product customization.
