GE PCI-5565 high-performance reflective memory card

The PCI-5565 is a high-performance reflective memory interface card designed for real-time data sharing across distributed systems, enabling deterministic communication with minimal latency. It combines robust hardware architecture with flexible connectivity to address critical applications requiring high-speed data synchronization.

Detailed content

Technical Specifications:

 

  • Data Transfer: Supports sustained rates up to 174 MB/s (64-byte packets) with deterministic latency (450–500 nanoseconds between nodes) .
  • Memory Capacity: Configurable 64 MB or 128 MB onboard SDRAM for shared memory space, with hardware-based error detection (CRC) and parity checking .
  • Network Interface:
    • Fiber-optic connectivity: Multimode up to 300 meters, single-mode up to 10 kilometers .
    • Dynamic packet sizing (4–64 bytes) optimizes data flow for varying application requirements .
  • Bus Interface: PCI 64-bit/66 MHz compliant, supporting plug-and-play integration with standard PCI slots .
  • Power: Requires +5V DC and ±12V DC inputs, with typical power consumption ≤8W under full load .
  • Environmental:
    • Operating temperature: -40°C to 85°C (extended industrial range) .
    • Compliance: Meets EMI/EMC standards (EN 61000-6-2/3) and withstands shock (50g) and vibration (5–500 Hz) .

 

Functional Features:

 

  • Software Transparency: Data writes to local memory are automatically broadcast to all network nodes without host CPU intervention, eliminating I/O overhead .
  • Scalability: Supports up to 256 nodes in a single optical ring topology, ensuring seamless expansion for large-scale systems .
  • Real-Time OS Support: Compatible with Windows, Linux, VxWorks, and QNX, enabling deterministic task scheduling and low-latency control .
  • Advanced Interrupts: Four independent network interrupts with 32-bit data payloads allow cross-node signaling for critical events .
  • DMA Support: Dedicated DMA channels offload data transfer processing from the host CPU, maintaining sustained throughput during peak loads .
  • Redundancy: Optional dual-ring architecture provides fault tolerance, with automatic failover in case of fiber optic failure .

 

Application Scenarios:

 

  • Industrial Automation: Synchronizes PLCs, distributed control systems, and robotics in smart factories, ensuring nanosecond-level timing for conveyor systems and quality control .
  • Aerospace and Defense: Used in flight simulators and avionics testing to share sensor data and real-time telemetry between multiple compute nodes .
  • Medical Imaging: Facilitates rapid data exchange between MRI/CT scanners and image processing workstations, enabling real-time 3D reconstruction .
  • Energy Management: Implements grid-scale monitoring in smart grids, coordinating power distribution and renewable energy integration across geographically dispersed nodes .
  • Scientific Research: Manages high-speed data streams from particle accelerators and telescopes, ensuring precise synchronization of experimental setups .
