VMIVME-5565  反射式存储器节点卡

【产品详情】

概述

VME-5565 反射式存储器节点卡提供高速、低延迟、确定性接口，允许在多达 256 个独立系统（节点）之间以高达 170 MB/s 的速率共享数据。每个反射式存储板都可以配置64 MB或128 MB的板载SDRAM。本地 SDRAM 提供对存储数据的快速读取访问时间。写入存储在本地SDRAM中，并通过高速光纤数据路径广播到其他反射式存储器节点。节点之间的数据传输是软件透明的，因此不需要 I/O 开销。发送和接收FIFO在峰值数据速率期间缓冲数据，以优化处理器和总线性能，以保持高数据吞吐量。

【英文介绍】

summarize

The VME-5565 reflective memory node card provides a high-speed, low-latency, deterministic interface that allows data to be shared between up to 256 independent systems (nodes) at rates of up to 170 MB/s. Each reflective memory board can be configured with either 64 MB or 128 MB of onboard SDRAM. Local SDRAM provides fast read access time to stored data. Writes are stored in local SDRAM and broadcast to other reflective memory nodes via high-speed fiber data paths. Data transfers between nodes are software-transparent, so there is no I/O overhead. Transmit and receive FIFOs buffer data during peak data rates to optimize processor and bus performance to maintain high data throughput.

Network transfer rates from 43 MB/s (4-byte packets) to 170 MB/s (64-byte packets)

Dynamic packet size, 4 to 64 bytes of data

Up to 256 nodes

The multi-mode fiber is up to 300 meters long and the single-mode fiber is up to 10 kilometers long

Data written to memory in one node is also written to memory in all nodes on the network

High-speed, easy-to-use fiber optic network (serial 2.12 Gbaud)

VME transfer rate 40 MB

64 MB or 128 MB SDRAM reflective memory

Support for interrupt transmission of any node

128 or 256 MB of onboard SRAM

The GE Fanuc/VMIC VMIVME-5565 Reflective memory node card is an aural-based, ultra-high-speed shared memory network solution. It allows a distributed network to share real-time data at a deterministic rate, regardless of bus structure and operating system. It centers on an innovative and efficiently designed hardware platform that is easy to use, offers greater distance between nodes, high noise resistance, optional node bypass, and no software overhead. Just read and write to the onboard memory, and the reflective memory node controller does the rest.
