– Key Features
Dual independent PCI buses eliminate bottlenecks in high-bandwidth data flows. The 2eSST VME interface provides 180 MBytes/s for deterministic real-time synchronization and message passing. Processor variants support AltiVec™ vector acceleration on select models. Global memory operates at cache speed with 400 MBytes/s aggregate bandwidth.
– Typical Applications
Real-time signal processing, high-speed data acquisition, embedded avionics, military and aerospace computing systems, and industrial control requiring VME-based modular architectures.
– Compatibility & Integration
Board Support Packages available for LynxOS®, VxWorks®, Integrity®, TimeSys®, and Linux® with network protocol support (TCP/IP and CES BP-Net channel mode). VME64x-LI/D64 BMA compliance with full CR/CSR integration ensures seamless integration into existing VME systems.
