Abaco Systems / VMIC VMIVME-5588-310 High-Speed Fiber-Optic 1.2 Gbaud Reflective Memory with Interrupts

The Abaco Systems / VMIC VMIVME-5588-310 is a high-speed fiber-optic reflective memory board for VMEbus systems that enables deterministic, low-latency data sharing across distributed nodes. Operating at 1.2 Gbaud serially, this single-slot 6U module supports up to 256 nodes in a daisy-chain ring topology. Data written to local SRAM is automatically broadcast to all networked nodes without software intervention or I/O overhead - ideal for real-time applications demanding tight synchronization.

Technical Specifications

• Data Transfer Rate: 1.2 Gbaud serial


• Maximum Throughput: 29.5 Mbyte/s (standard mode); 14.8 Mbyte/s (redundant transfer mode)


• Supported Nodes: Up to 256 on daisy-chain ring topology


• On-board Memory: Configurable SRAM from 256 Kbyte to 16 Mbyte; SDRAM in DMA variants


• Memory Access: A24:A32:D32:D16:D8

• MTBF: 88,005 hours (217F)

Key Features

• Software-transparent reflective memory architecture eliminates I/O overhead


• Inter-node interrupt capability - any node can trigger interrupts to single or multiple targets with data sequencing guarantees


• Error detection and redundant transmission mode for fault tolerance


• Configurable memory capacity to match application requirements


• DMA controller available on VMIVME-5588DMA variant

Typical Applications Distributed real-time simulation, multiprocessor synchronization, industrial control systems, and latency-critical data acquisition networks requiring deterministic performance across geographically dispersed nodes.
