>>>>>型號:MVME5500-0161 本地總線和I/O子系統(tǒng)平衡
【功能描述】
SMART嵌入式計算的MVME5500使用MPC7457處理器運行在
1 GHz，與內(nèi)存、雙獨立本地總線和I/O子系統(tǒng)平衡。
功能強大的Marvell系統(tǒng)控制器，支持133 MHz主機總線和133 MHz
SDRAM存儲器總線，很好地匹配了高速處理器。
為了將系統(tǒng)I/O與出色的處理器性能相匹配，MVME5500提供
雙64位，33/66 MHz PCI總線。每個PCI總線都有一個PMC站點，支持運行的卡
33或66兆赫。Universe II VME接口和PMCspan連接器與
PMC站點在專用的33 MHz PCI總線段上，以便兩個PMC站點都能夠
66 MHz操作。
MVME5500還提供千兆以太網(wǎng)接口，10/100BaseTX以太網(wǎng)接口
還有兩個串口。所有這一切加起來，一套良好的平衡，高性能
子系統(tǒng)無與倫比的性能。
MVME5500系列旨在滿足oem的需求，包括國防和國防領域的oem
航空航天、工業(yè)自動化和交通運輸。尋找技術的客戶
刷新應用程序，同時保持與現(xiàn)有應用程序的向后兼容性
VMEbus基礎設施可以升級到MVME5500系列，并利用
增強的性能特性。

【英文介紹】
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.
