1999年8月11日 · IACK* Interrupt acknowledge [IACK*] is driven by interrupt handlers in response to interrupt re-quests. It is connected to IACKIN* at slot 01 (on the backplane), and used by the IACK* daisy-chain driver to start propagation of the [IACKIN* - IACKOUT*] daisy-chain.

2023年11月21日 · IACK* An interrupt handler uses this signal to indicate that it has received an interrupt and is ready to receive a status/ID that will tell the handler how to proceed with servicing the interrupt. IACKIN*/ IACKOUT* A module receives the …

In 6U and 9U systems there can be transition modules installed on the rear side of the backplane. Transition modules do not connect to VMEbus but just to the VMEbus module on the opposite side of the backplane via the user defined pins of the J0, J2 and J3 connectors.

2019年4月30日 · VME (Versa Module Eurocard)总线是一种计算机总线结构，VME总线系统采用主控／目标结构、异步非复用传输模式，支持16位、24位、32位寻址及8位、16位、24位、32位数据传输，最大总线速度是40 MB／s。 1996年的新标准VME64 (ANSI／VI-TA1-1994)将总线数据宽度提升到64位，最大数据传输速度为80 MB／s。 而由FORCE COMPUTERS制定的VME64x总线规范将总线速度提高到了320 MB／s。 历史上，VME总线由于其众多的功能、强大的兼容性 …

2023年7月5日 · 在深入分析多处理器系统中基于fpga的vme总线接口设计前，需要对vme总线和fpga的基本知识有所了解。 VME 总线 （VersaModule Eurocard），是一种广泛应用于多处理器系统中的高性能计算机 总线 技术，它具有并行性、实时性...

Most VME lines are direct connections between the same pin on every connector. Exception: Interrupt Acknowledge daisy chain line (IACKIO). Two state logic Can be driven high (1) or low (0) by one (or more) VME devices. Lines float high when un-driven. Control signals use inverted logic (True=0) for this reason. eg.

In 6U and 9U systems there can be transition modules installed on the rear side of the backplane. Transition modules do not connect to VMEbus but just to the VMEbus module on the opposite side of the backplane via the user defined pins of the J0, J2 and J3 connectors.

2024年11月26日 · VXI(VME bus Extension for Instrumentation)， 是VME bus在仪器领域的扩展； 一种用于模块化仪器的总线系统； 规定了系统主机箱机械结构尺寸、插件的尺寸、 连接器、电磁兼容、机箱冷却及电源等方面的要求； 常见的有13槽机箱和9槽机箱。

1999年9月19日 · The IACK daisy chain driver is a simple circuit which insures the proper timing relationship between IACK and the IACK IN/OUT signal during interrupt acknowledge cycles. The VMEbus is made up of four sub buses. One of the sub …

The VMESCmodule2 is Inicore's next generation VME System Controller core designed for FPGA and ASIC integrations. The core contains VME Slave and Master functions as well as System Controller features such as bus timer, arbiter, IACK daisy-chain driver, system clock driver and provisioning for CSR.
