>>>>>型号:MVME5500 VMEbus 单板计算机 用于高性能计算应用的AltiVec协处理器
【功能描述】
特征：
1 GHz 的 MPC7450 系列 PowerPC 处理器
512 KB 片上 L2 缓存和 2 MB L3 缓存
用于高性能计算应用的AltiVec协处理器
两组焊接闪存
双独立 64 位 PCI 总线和 PMC 站点
艾默生/摩托罗拉 MVME5500 系列 VMEbus 单板计算机旨在满足 OEM 的需求，包括国防和航空航天、工业自动化和医学成像细分市场。如果客户希望对其应用进行技术更新，同时保持与现有 VMEbus 基础架构的向后兼容性，则可以升级到 MVME5500 系列并利用增强的性能特性。
该MVME5500采用运行频率为 1 GHz 的 MPC7457 处理器，非常适合数据密集型应用。MVME5500 不仅提供更好的处理器性能;它还通过处理器、内存、双独立本地总线和 I/O 子系统提供平衡的性能。
功能强大的 Marvell 系统控制器支持 133 MHz 主机总线和 133 MHz SDRAM 内存总线，与高速处理器完美匹配。为了使系统 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，支持以 33 或 66 MHz 运行的卡。Universe II VME 接口和 PMCspan 连接器通过专用的 33 MHz PCI 总线段与 PMC 站点隔离，因此两个 PMC 站点都能够以 66 MHz 运行。
该MVME5500还提供一个千兆以太网接口、一个 10/100BaseTX 以太网接口和两个串行端口。所有这些加起来就是一组均衡的高性能子系统，可实现无与伦比的性能。

【英文介绍】
Features:
1 GHz MPC7450 series PowerPC processors
512 KB on-chip L2 cache and 2 MB L3 cache
AltiVec coprocessor for high-performance computing applications
Two sets of welded flash memory
Dual independent 64-bit PCI bus and PMC site
The Emerson/MOTOROLA MVME5500 series VMEbus single-board computers are designed to meet the needs of Oems, including the defense and aerospace, industrial automation, and medical imaging segments. If customers want to make technical updates to their applications while maintaining backward compatibility with their existing VMEbus infrastructure, they can upgrade to the MVME5500 series and take advantage of enhanced performance features.
The MVME5500 is powered by an MPC7457 processor operating at 1 GHz, making it ideal for data-intensive applications. The MVME5500 not only delivers better processor performance; It also provides balanced performance through processors, memory, dual independent local buses, and I/O subsystems.
The powerful Marvell system controller supports 133 MHz host bus and 133 MHz SDRAM memory bus, which is perfectly matched with high-speed processors. To match system I/O with outstanding processor performance, the MVME5500 offers dual 64-bit 33/66 MHz PCI buses. Each PCI bus has a PMC site that supports cards running at 33 or 66 MHz. The Universe II VME interface and PMCspan connector are isolated from the PMC site via a dedicated 33 MHz PCI bus segment, so both PMC sites are able to operate at 66 MHz.
The MVME5500 also offers a Gigabit Ethernet interface, a 10/100BaseTX Ethernet interface, and two serial ports. All of this adds up to a balanced set of high-performance subsystems that deliver unmatched performance.
