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.
