RCNIC-A2PAU4 Interface

Dual port ARINC 664 4-lane PCI Express interface


Abaco Systems' RCNIC-A2PAU4 is a high performance 4-lane PCI Express interface for monitoring, generating or analyzing full-bandwidth AFDX/ARINC 664 protocol traffic. Our exclusive pipeline architecture maximizes packet throughput using parallel controllers and efficient DMA transfers, thereby avoiding the bottlenecks of CPU-based interface solutions.

Configurable as either one dual-redundant AFDX/ARINC 664 interface or two independent ports, users have complete access to all frame and header data. Each incoming packet is tagged with a 20 nsec resolution, 64-bit time-tag. Real time traffic generation is highly accurate. An IRIG-B receiver/generator is included for synchronization to external IRIG-B time sources and for synchronizing multiple RCNIC-A boards. In addition, I/O triggers, error detection/injection, BIT, and link/protocol level statistics are provided.

The RCNIC-A2PAU4 comes with all the software development tools needed for user application development at no extra charge. The Cpcap packet capture library provides a complete set of functions for transmitting and receiving Ethernet frames.
