Architecture
GE Intelligent Platforms CNIC-A2PU4 is a 
high performance interface for monitoring, 
generating or analyzing full-bandwidth 
AFDX/ARINC 664 protocol traffic. GE 
Intelligent Platforms 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 indepen-
dent 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 genera-
tion is highly accurate. An IRIG-B receiver/
generator is included for synchronization 
to external IRIG-B time sources and for 
synchronizing multiple CNIC-A boards. In 
addition, I/O triggers, error detection/injec-
tion, BIT, and link/protocol level statistics 
are provided.

Advanced Software Support
Multiple CNIC-As in the same PC have been 
benchmarked at full bandwidth supporting 
all channels with 2000 VLs (Virtual Links), 
multiple Ports on each VL and minimum 
payloads (17 bytes).

Advanced Software Support
The CNIC-A2PU4 comes with all the soft-
ware 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.

Frames from multiple ports can be logged 
or replayed using the open-source ntar log-
file format . CFDX implements the ARINC 
664/AFDX protocol stack including End 
Systems, redundancy management , Virtual 
Links, and Ports. An advanced XML-based 
Configuration File format is used to specify 
End Systems, and an AFDX-aware version of 
Ethereal is included to provide GUI analysis 
of logged files.
