The Abaco Systems/VMIC PCI-5565-110 Reflective Memory Interface is a PCI-based network adapter enabling deterministic, low-latency data sharing across distributed systems. Data written to memory on any node automatically broadcasts to all other nodes on the network, eliminating host processor overhead and I/O bottlenecks. The interface supports up to 256 independent nodes connected via fiber optic links, delivering peak throughput of 174 Mbyte/s with 64-byte packets and sustained operation at 43 Mbyte/s with 4-byte packets.

– Key Features

• Software-transparent data transfer with no host processor involvement
• Transmit and Receive FIFOs buffer peak-rate traffic for optimized bus performance
• Any node can generate interrupts to single nodes or broadcast to all nodes via single command
• Four user-definable interrupt levels with data-following acknowledgment
• Error detection with redundant transfer mode for enhanced suppression
• One independent DMA channel

– Typical Applications

• Real-time control systems requiring deterministic latency
• Distributed data acquisition networks
• Multi-node synchronized operations in demanding aerospace and defense environments
