>>>>>型号:MVME5500-0161 本地总线和I/O子系统平衡
【功能描述】
SMART嵌入式计算的MVME5500使用MPC7457处理器运行在
1 GHz，与内存、双独立本地总线和I/O子系统平衡。
功能强大的Marvell系统控制器，支持133 MHz主机总线和133 MHz
SDRAM存储器总线，很好地匹配了高速处理器。
为了将系统I/O与出色的处理器性能相匹配，MVME5500提供
双64位，33/66 MHz PCI总线。每个PCI总线都有一个PMC站点，支持运行的卡
33或66兆赫。Universe II VME接口和PMCspan连接器与
PMC站点在专用的33 MHz PCI总线段上，以便两个PMC站点都能够
66 MHz操作。
MVME5500还提供千兆以太网接口，10/100BaseTX以太网接口
还有两个串口。所有这一切加起来，一套良好的平衡，高性能
子系统无与伦比的性能。
MVME5500系列旨在满足oem的需求，包括国防和国防领域的oem
航空航天、工业自动化和交通运输。寻找技术的客户
刷新应用程序，同时保持与现有应用程序的向后兼容性
VMEbus基础设施可以升级到MVME5500系列，并利用

【英文介绍】
The MVME5500 from SMART Embedded Computing uses the MPC7457 processor running at
1 GHz, balanced with memory, dual independent local buses and I/O subsystems.
The powerful Marvell system controller, with support for a 133 MHz host bus and a 133 MHz
SDRAM memory bus, is well matched to the high speed processor.
To match the system I/O to the outstanding processor performance, the MVME5500 provides
dual 64-bit, 33/66 MHz PCI buses. Each PCI bus has a PMC site supporting cards running at
33 or 66 MHz. The Universe II VME interface and PMCspan connector are isolated from the
PMC sites on a dedicated 33 MHz PCI bus segment so that both PMC sites are capable of
66 MHz operation.
The MVME5500 also offers a Gigabit Ethernet interface, a 10/100BaseTX Ethernet interface
and two serial ports. All of this adds up to a set of well-balanced, high-performance
subsystems for unparalleled performance.
The MVME5500 series is designed to meet the needs of OEMs including those in defense and
aerospace, industrial automation and transportation. Customers looking for a technology
refresh for their application while maintaining backward compatibility with their existing
VMEbus infrastructure can upgrade to the MVME5500 series and take advantage of the
enhanced performance features.
