FREMONT, CA: Avionics Interface Technologies (AIT), a provider of military and commercial applications solutions, unveils its new Shared Memory Network (SMN) interface products to provide host systems with an interface to high speed optical data network that can be used to share data in real time between multiple distributed systems.

The company’s SMN product line includes PCI-SMN Interface Card; PCIe-SMN Interface Card; PXIe-SMN Interface Card; and XMC-SMN Interface Card. The ring based network allows data to be shared with deterministic timing and at high data rates up to 2.125Gbps to support a wide variety of real-time hardware-in-the-loop simulations, automotive system simulations and industrial automation.

Protocol overhead that limit transfer speeds of small data transfers such as 4, 8 and 16 bytes in a network accounts for majority of traffic. SMN has no protocol overhead and is designed to move small amount of data efficiently. It results in data transportation almost at the line rate speed thus reducing greater amount of communication time and simulation time. It supports single-mode and multi-mode optical interfaces, minimizes the network size and allows users to save time and investment in network hardware.

SMN is capable of allowing event-driven interrupts for promoting instantaneous actions as required in hardware-in-the-loop simulations. Fault status and fault information is sent simultaneously over a network enabling time critical interruptions to benefit most by cutting down on the time that can potentially cause system failures.
