Adapting Ethernet for the Battlespace
Steve Rood Goldman, Data Device Corp.

Commercially derived host offload and service performance protocols can be used to help adapt Gigabit Ethernet technology to the needs of military system design.

Defense Platforms Get Ready for IPv4/v6
Nauman Arshad, Curtiss-Wright Controls Embedded Computing

A shift from parallel buses to switched intra-platform network architectures is enabling the transformation to IPv6 in battlefield platforms. In VME systems, this has begun with the introduction of switched Gigabit Ethernet.

FPGA-Based SDR Platforms Ease Military Comms Challenges
Nick Garnett, Spectrum Signal Processing

The steady advance of Software Defined Radio technologies has enabled a wealth of ready-made platforms suited for next-gen military communications programs such as JTRS.

FPGAs Edge Out GPPs for Advanced Signal Processing Apps
Bob Walsh, TEK Microsystems

General-purpose processors (GPPs) suffer an inherent imbalance between I/O and processing. FPGA-based processing is emerging as a better alternative for signal processing chores such as advanced radar designs.
