VMIVME-5521 总线处理器 链路模块

【产品详情】

特征：

用户可选配置

VMEbus 中断转换为 ISA 中断

80386SX 或更高版本的 ISA 总线处理器，具有对 VMEbus 资源的完全访问权限

四个独立的 512 K VME 窗口，提供灵活性

VMIC / GE Fanuc VMIVME-5521 / VMIATX-5521 ISA 总线到 VMEbus 链路模块是一种高性能且易于使用的方法，通过电缆和一对适配器板将 ISA 总线与 VMEbus 机箱连接在一起。该模块在 ISA 内存寻址空间中出现的四个独立“窗口”内提供 A32、A24 和 A16 VMEbus 寻址。该链路可以以 16 位和 8 位大小传输数据，并且支持未对齐的传输。七个可能的 VMEbus 中断中的每一个也可以分配给四个 ISA 中断中的一个。所有传输都作为 ISA 内存操作执行，因此不支持 DMA 传输。

该装置是VMIC系列设备的一部分，最初由通用电气的工业自动化部门设计和生产。这些最初由通用电气生产，但后来停产了。然后，它们被Abaco Systems收购。VMIC系列是一系列可用作各种设备的电路板，例如CPU模块、模数转换器电路板以及输入和输出电路板。该装置被指定为 VMIVME-5521 型号，是 VMEbus Link 模块的微通道。

VMIVME-5521 设计具有 VMIC 系列中的多项标准功能，例如用户可选择的设备配置。在使用时，VMEbus 会中断，然后转换为 ISA 中断。8038SX ISA 总线处理器模块集成在设备中，完全能够访问 VMEbus 资源。

VMIVME-5521 型号是一款高性能、易于使用的设备，通过电缆和一对适配器板，通过设备的 VMEbus 机箱将该总线和 ISA 总线连接在一起，方法很简单。VMIVME-5521 单元的寻址能够提供 A32、A24 和 A16 VMEbus 独立窗口，出现在可用的 ISA 内存空间内。

【英文介绍】

Features:

This parameter is optional

The VMEbus interrupt is converted to an ISA interrupt

80386SX or later ISA bus processor with full access to VMEbus resources

Four separate 512K VME Windows for flexibility

The VMIC/GE Fanuc VMIVME-5521 / VMIATX-5521 ISA Bus to VMEbus link module is a high performance and easy to use method that connects the ISA bus with the VMEbus chassis via a cable and a pair of adapter boards. The module provides A32, A24, and A16 VMEbus addressing within four separate "Windows" that appear in the ISA memory addressing space. The link can transmit data in 16-bit and 8-bit sizes and supports unaligned transfers. Each of the seven possible VMEbus interrupts can also be assigned to one of the four ISA interrupts. All transfers are performed as ISA memory operations, so DMA transfers are not supported.

The device is part of the VMIC family of devices, originally designed and produced by GE's Industrial automation division. These were originally produced by General Electric, but have since been discontinued. They were then acquired by Abaco Systems. The VMIC family is a family of circuit boards that can be used as a variety of devices, such as CPU modules, analog-to-digital converter boards, and input and output boards. The device, designated VMIVME-5521, is a microchannel for the VMEbus Link module.

The VMIVME-5521 is designed with a number of standard features in the VMIC family, such as user selectable device configurations. When in use, VMEbus interrupts and then converts to ISA interrupts. The 8038SX ISA bus processor module is integrated into the device and has full access to VMEbus resources.

The VMIVME-5521 model is a high performance, easy to use device with a cable and a pair of adapter boards that connect the bus and ISA bus together via the device's VMEbus chassis in a simple way. The addressing of the VMIVME-5521 unit is capable of providing A32, A24, and A16 VMEbus independent Windows that appear within the available ISA memory space.
