New Performance Breakthrough for VxWorks-based HPEC Systems

August 01, 2018 | BY: Michelle Watson

For years, designers of HPEC systems have sought to free up critical resources and establish optimal performance for Intelligence, Surveillance and Reconnaissance (ISR) applications.  Today, system designers can take full advantage of the Intel Xeon D processor architecture for their multi-core/multi-board HPEC systems using VxWorks.

The Wind River VxWorks Board Support Package (BSP) for the Intel Xeon D processor-based CHAMP-XDx modules is now the first to provide support for the QuickData Technology DMA engine and 40 Gigabit Ethernet (GbE) Mellanox Ethernet Controller, a performance breakthrough in design of High Performance Embedded Computing (HPEC) systems for ISR applications, from Curtiss-Wright.

This unique, high-value design is based on the Wind River VxWorks real-time operating system (RTOS).  New software drivers included in Curtiss-Wright’s latest BSP are used in harmony with Curtiss-Wright’s CHAMP-XDx DSP modules.  This design enables VxWorks to access the Intel Xeon D processor’s QuickData Technology DMA engine, a feature once limited to Linux users.  Delivering peak performance, this solution also offers 40 GbE on Curtiss-Wright’s Fabric40 CHAMP-XD1 3U OpenVPX and CHAMP-XD2 6U OpenVPX DSP modules rated at ~37 Gbps, near line-rate, now freeing the multi-core processor from dedicating critical resources to communications handling.
