VMIVME-5550 反射式存储器接口 共享数据

【产品详情】

特征：

高达 4 MB 的反射式存储器

无处理器开销

多点功能（最多 16 个节点）

数据传输速度为 20 MB/s（50 英尺电缆）

高速、易用的并行网络

VMIVME-5550 反射式存储器接口允许在多达 16 个独立的 VMEbus 系统（节点）之间以高达 20 MB/s 的速率共享数据。每个反射式内存板可配置 256 KB 至 4 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，并通过高速并行数据总线广播到其他反射存储器节点。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 CPU 和总线性能，以保持高数据吞吐量。

VMIVME-5550 模块是 VMIC 系列产品中的一款设备，由一系列转换器板和 CPU 模块组成。该系列最初由通用电气的自动化工业产品部门生产，然后从生产中撤出，并由 Abaco Systems 收购和生产。VMIC模块在公司之间切换后，现在全部停产。AX Control Inc. 提供的装置由我们的技术人员进行全面翻新和维修。

VMIVME-5550 模块是一种反射式内存接口模块，旨在通过独立的 VMEbus 系统节点以高达 16 兆字节/秒的速率共享和传输高达 20 位的数据。 这些型号可配置高达 256 KB，或最多 4 MB 的板载同步动态随机存取存储器。本地同步动态随机存取存储器能够为模块提供对存储数据的快速、高质量的读取访问时间。节点之间的数据传输被设计为软件透明的，因此不需要输入和/或输出开销。VMIVME-5550 模块设计为能够在峰值数据额定值期间发送和接收 FIFO 缓冲器数据和文件，以优化 CPU 和 VMEbus 性能水平和功能，以便在传输过程中保持数据的高质量水平。

【英文介绍】

Features:

Reflective memory up to 4 MB

No processor overhead

Multipoint function (up to 16 nodes)

Data transfer speed of 20 MB/s (50 ft cable)

High speed, easy to use parallel network

The VMIVME-5550 reflective memory interface allows data to be shared between up to 16 independent VMEbus systems (nodes) at rates of up to 20 MB/s. Each reflective memory board can be configured with 256 KB to 4 MB of on-board SDRAM. Local SDRAM provides fast read access time to stored data. Writes are stored in local SDRAM and broadcast to other reflected memory nodes via a high-speed parallel data bus. 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 CPU and bus performance to maintain high data throughput.

The VMIVME-5550 module is a device in the VMIC family, consisting of a series of converter boards and CPU modules. The series was originally produced by General Electric's Automated Industrial Products division before being withdrawn from production and acquired and produced by Abaco Systems. After switching between companies, the VMIC modules are now all discontinued. Units supplied by AX Control Inc. are fully refurbished and repaired by our technicians.

The VMIVME-5550 module is a reflective memory interface module designed to share and transfer up to 20 bits of data at rates of up to 16 megabytes per second via independent VMEbus system nodes. These models can be configured with up to 256 KB, or up to 4 MB, of on-board synchronous dynamic random access memory. Local synchronous dynamic random access memory can provide the module with fast and high-quality access time to the stored data. The data transfer between nodes is designed to be software transparent and therefore requires no input and/or output overhead. The VMIVME-5550 module is designed to be able to send and receive FIFO buffer data and files during peak data ratings in order to optimize CPU and VMEbus performance levels and functionality in order to maintain a high level of data quality during transmission.
