Shared Memory

Shared Memory — Speedgoat I/O modules for shared memory

Introduction

Speedgoat offers support for shared memory for high speed data transfer between real-time target machines or third-party nodes.

Shared memory technology, also called reflective or replicated memory, is the most efficient way to transfer data in real-time with low latency across two or more target machines or third-party nodes. For this each target machine or node must be equipped with a shared memory I/O module from the same family. Nodes are connected via fiber-optic cables in various types of network topologies with up to 256 nodes.

The I/O modules support data transfer rates up to 2.5Gbit/s and data throughputs exceeding 170-210MB/s, compared to 125MB/s using Gigabit Ethernet connections.
