VMIC CPCI-5565PIORC-210000 Reflective Memory Board

Module Feature

VMIC CPCI-5565PIORC-210000 is a CPCI form factor reflective memory interface board. It supports high-speed real-time reflective memory network data transmission between multiple nodes, featuring low transmission latency and strong determinism. Onboard dedicated control logic to achieve automatic data mirroring across the whole network without heavy CPU intervention. Equipped with interrupt trigger mechanism and status register for system event notification. Rugged board-level design, good shock and vibration resistance, suitable for embedded industrial, test and simulation systems. Widely used in real-time simulation, aerospace test, distributed motion control applications.

Working principle

The reflective memory card maps a shared physical memory space across all network nodes. Once any node writes data to local memory, the hardware automatically broadcasts the data to all other reflective memory nodes on the network, updating their local memory copies immediately. The host CPU accesses the shared memory directly just like local RAM. Hardware interrupt signals can be sent between nodes for synchronization and event trigger.

Onboard components

Reflective memory controller, high-speed serial transceiver, shared memory chip, CPCI bus interface circuit, interrupt logic circuit, status LED indicators, external fiber/coax connector interface.

LED indicators

Front panel LED indicators for power status, network link, data activity and fault alarm.

Hardware self-diagnosis

Visual inspection of PCB, connectors and soldering joints; register readback test for board identification and firmware version; memory read/write loop test; network link and node communication test; interrupt function verification.

Programming software

VMIC Reflective Memory driver and API library, supporting Windows, VxWorks, Linux real-time operating systems, configuration utilities for node ID, memory size and interrupt setup.
