Overview
The Curtiss-Wright DY 4 SVME-179 is a MIL-spec PowerPC single board computer designed for demanding industrial automation, defense, and aerospace environments. Originally manufactured by DY 4 Systems (now part of Curtiss-Wright), the SVME-179 delivers high-performance computing in a compact form factor with proven reliability in avionics, tactical ground vehicle, and naval applications.
Key Features
- 64-bit PowerPC Architecture – High-performance processing for complex control and real-time applications
- Configurable Memory – Up to 48 MB of direct memory-mapped 64-bit Flash; 64–256 MB synchronous DRAM with ECC
- Low Power Consumption – Only 17 Watts typical (with 750 CPU), ideal for thermally constrained environments
- High-Speed L2 Cache – 1–2 MB cache with parity protection; 1.06 GBytes/sec peak transfer rate at 133 MHz
- Error Checking & Correction (ECC) – Detects and corrects single-bit errors; detects multi-bit errors for mission-critical reliability
- VME Bus Compatibility – Standard VMEbus interface for integration into chassis-based systems
