Overview
The VPX-COMEX is a 3U OpenVPX system controller CPU card that
integrates an Intel CPU COM Express CPU module with SRIO switch, system
timing and triggering features, and a Spartan6 FPGA core. The VPX-COMEX
supports VPX systems with up to 4 other PCIe /SRIO cards and
timing/triggering support for embedded communications. instrumentation,
and data acquisition applications.
The CPU core is a COM Express module, a PICMG industry standard, that
is an Intel-architecture I7 or I5 CPU with QM57 chipset . The COM Express
module runs Windows, Linux, or VxWorks, providing a familiar and
easy-to-use software environment that is abundant in tools and
applications, resulting in dramatically lower time-to-market than other
CPU architectures.
The VPX-COMEX has support for 4 expansion cards using PCI Express and
SRIO. The PCI Express root complex has x4, x4, x1 and.x1 Gen1 endpoint
support, provided by the chipset. The SRIO data plane complements the PCIe
connectivity with a central switch providing 8 SRIO Gen2 links (5 Gbps
each).
Timing and triggering features support system-wide synchronized data
acquisition. The VPX-COMEX provides precision, low jitter sample clocks
and synchronized triggers both over VPX backplane and front panel
connections. The timing sub-sytem includes a PLL with external or on-card
references capable of sample rates up to 1 GHz.
A Xilinx Spartan6 FPGA core connects the CPU core with the peripheral
device and SRIO data plane. A 128MB DDR3 memory is provided for the FPGA.
Framework Logic tools support development on the FPGA for custom DSP and
system interfaces.
The VPX-COMEX is designed for embedded operation in conduction-cooled
or forced-air VPX systems. IPMI functions support system management and
monitoring. The card requires a 1in slot (clearance for optional QSFP is
also required). REDI covers are available for 2-level maintenance.
Software tools for host development include C++ libraries and drivers
for VxWorks,Windows and Linux. Application examples demonstrating the
module features are provided.
