COTS Card Exploits Freescale Dual Processor

September, 13 2007
The Phoenix VPF2 is a
rugged COTS DSP processing
card that integrates
a Freescale
MPC8641D processor, two Xilinx
Virtex-5 FPGAs, and a VXS based
high-speed serial inter-connect
fabric. Introduced by VMETRO,
the VPF2 is a 6U VME64/VITA
41 card that tackles high-bandwidth
pre-processing and backend
processing in DSP applications,
such as real-time video processing,
surveillance, and radar.
The processing heart of the
Phoenix VPF2 is a Freescale
MPC8641D dual-core processor
based on Power Architecture technology.
The cores run up to
1.25GHz with 2GB of memory to
support operating systems like
VxWorks and Linux. Integrated
within the MPC8641D processor
is a complete I/O subsystem,
including two Gigabit Ethernet
ports, serial I/O, dual DDR/
DDR2 memory controllers, VME
interface, and independent x8
PCI Express links to the Xilinx
FPGAs and the XMC/PMC site.
The VPF2 has Ethernet options
that support both RJ45 and optical
interfaces or backplane I/O.
LabVIEW now programs
multicore processors
The latest version of LabVIEW
8.5, a graphical system design
platform for test, control and
embedded system development,
extends the platform to program
multicore, real-time processors.
In this new version, National
Instruments combined LabVIEW
software with commercial multicore
hardware. It also introduces
the LabVIEW Statechart Module
for higher-level designs to run on
targets that include FPGAs, realtime
systems, PDAs, touch panels,
and a variety of microprocessors.
With the inherent parallel nature
of LabVIEW graphical code,
embedded developers can
enhance applications ranging
from design validation systems
(e.g., hardware-in-the-loop simulators)
to complex control systems
(e.g., high-speed particle accelerators).
To achieve real-time symmetric
multiprocessing, NI developed
a real-time load-balancing
scheduler to automatically assign
tasks to different processor cores,
providing performance boosts
without sacrificing determinism or
requiring user code changes.
With LabVIEW 8.5, users can
also manually assign portions of
code to specific processor cores
to fine-tune real-time systems or
isolate time-critical tasks on a
dedicated core.
The LabVIEW Statechart
Module can be utilised to design
software combined with realworld
I/O running on deterministic
real-time or FPGA-based hardware
with familiar, high-level statechart
notations.
Module accelerates
ATCA design
A novel power interface module
will find homes in applications
that comply with the
Advanced Telecom Computing Architecture (ATCA) specifications.
According to developer
SynQor, the iQor
Power Interface
Module provides
designers with the
smallest available
overall power solution
for carrier card designs.
The Interface Module, when
coupled with a payload dc-dc
converter (such as the company’s
PQ60120QEA25), offers a
comprehensive solution for
ATCA board designs. Only a
handful of fuses and hold-up
capacitors need to be added
externally in order to support
the ATCA specifications.
The Interface Module features
a 5V/150mA rail to support
the ubiquitous Blue LED. In
addition, it has a programmable
hold-up capacitor voltage
that offers an output from 50V
to 95V, which cuts down on the
amount of capacitance needed.
A single external resistor sets
this value. When the resistor is
set to a value of 90V, just
564°F of external hold-up
capacitance is required to
achieve 8.70ms of hold-up time
with a 200W load.
FlexRay gets put to the test
TTTech Automotive’s customers
can now get their hands on TTXOptical
Link, a compact device
for electrical decoupling of
FlexRay bus signals for EMC
testing. The Link enables bidirectional
optical transmission of
FlexRay signals while ensuring
minimum influence on the
FlexRay signal’s bit timing.
The device converts FlexRay
signals to optical signals via
fibre cable and vice versa. With
its shielded housing and built-in
accumulator, it fulfills all of the
requirements to run EMC tests for
FlexRay-based systems. It therefore
allows full access to the
FlexRay signals using common
FlexRay analysis tools.
TTTech Automotive
is TTTech’s subsidiary
for FlexRay solutions.
GbE Board tackles
Layer2/3 network design
Claimed as the first highdensity
6U VPX Gigabit
Ethernet (GbE) multilayer
switch/router board designed for
rugged embedded aerospace
and defence applications, the
VPX6-684 FireBlade II comes
with 12, 20, or 24 GbE ports
and up to 4x10GbE ports.
The board, developed by
Curtiss-Wright Controls
Embedded Computing, operates
as either a fully managed or an
unmanaged switch/router. It provides
performance and configuration
advantages to developers
building Layer 2 or Layer 2/3+
networks, says the company.
Thanks to support for a de facto‚
standard CLI, the FireBlade II
should cut time to market by
reducing setup, configuration,
and maintenance times.
