Curtiss-Wright / Systran SCRAMNet AHSB-DPCIG02M-T PCI Module

The Curtiss-Wright/Systran SCRAMNet AHSB-DPCIG02M-T is a PCI-based shared-memory module engineered for deterministic, ultra-low-latency data distribution across networked nodes. Built on replicated shared-memory architecture, this single-slot card eliminates the overhead and unpredictability of conventional networking protocols, delivering sub-microsecond system latency and 250 nSec/node propagation delay. The design allows host processors to focus entirely on application-specific computation rather than protocol management.

## Technical Specifications

• **Bus Interface:** PCI
• **Form Factor:** PCI Module (SC150e PCI)

## Key Features

• ASIC-based core logic handles message arbitration, network control, memory management, interrupt handling, error detection/correction, and node configuration
• Generates two external trigger outputs via the Address Control Register: host-access trigger and network-write trigger
• Host processor and operating system independence at each node
• “On-time, every-time” deterministic performance for precision-critical operations

## Typical Applications

• High-fidelity simulation environments
• Real-time data acquisition systems
• Distributed control architectures requiring synchronized node operation

## Compatibility & Integration

Backward compatible with SCRAMNet Classic and SCRAMNet+ products, except for GOLD RING communication protocol. Integrates into standard PCI backplanes across computing platforms.
