The Curtiss-Wright/Systran SCRAMNet A-HS-DPMCG02M-20 is a PMC (PCI Mezzanine Card) module engineered for high-speed, deterministic data communication in real-time distributed systems. It implements the SCRAMNet+ Network architecture, based on replicated shared-memory concepts optimized for ultra-low-latency data exchange across multiple nodes. The module eliminates complex communication protocols by presenting shared memory directly to the host processor, reducing CPU overhead and enabling precise synchronization in demanding applications including high-fidelity simulations, data acquisition, and synchronized control systems.
