| Dear Sir/Madam
In
four weeks time there will be the embedded community meeting
at the exhibition centre in Nuremberg to show their newest products
and developments and discus new technologies at Embedded World
2008. This newsletter gives a short preview. Enjoy!

Fanless
Embedded Computers (Axiomtek)
The
eBOX630-830-FL and eBOX830-831-FL are two fanless embedded computers
that support ultra-low-voltage Intel Celeron M and Intel Core
2 Duo processors, respectively. The eBOX630-830-FL offers high-performance
computing power, a very compact appearance, and rich video connections.
The eBOX830-831-FL has one PCI slot reserved for expansion and
supports both the socket-type Intel Celeron M processor and
the onboard-type Intel Core 2 Duo processor. I/O features include
six high-speed USB 2.0 ports, four COM ports, two Firewire (IEEE
1394a), dual Gigabit Ethernet, and audio.

nanoETXexpress
COM (Kontron)
The
Kontron nanoETXexpress-VX8 is the first member of a new scalable
family of nanoETXexpress COMs (computers-on-modules), a logical
addition to the existing PCI- and/or ISA-based COM standards,
X-board and DIMM-PC. Designed according to the pin definitions
of the COM Express specification, the modules suit the emerging
generation of mobile embedded applications that require low
power performance and the latest interfaces on the smallest
form factor.

DSP/FPGA
AdvancedMC Module (CommAgility)
Designed
around four TMS320C6455 DSPs from TI running at 1GHz and a Virtex-4
FX100 series FPGA from Xilinx, the AMC-D4F1 module addresses
developers' needs in many aspects of high-end signal processing,
from wireless baseband through to image processing and aerospace
applications. Since it is based on the AdvancedMC embedded standard,
it is particularly appropriate for MicroTCA but also usable
in AdvancedTCA systems.

CompactPCI
CPU Board (EKF)
The
CCG-RUMBA is a versatile 4HP/3U (single-size Eurocard) CompactPCI
CPU board, equipped with an Intel Core 2 Duo T7500 processor
at 2.2GHz clock, and up to 4Gbytes dual-channel DDR2 RAM. Alternatively,
the Core 2 Duo LV (L7500) or ULV (U7500) processors are available
for downscaling.

PIR-Sensor
Motion Detection
PIR
(pyroelectric infrared) sensors are extremely useful for detecting
the presence of a moving body. This is due to their ability
to sense the infrared radiation that every living body emits.
The article by Lars Thornqvist from Future Electronics shows
that though they have a relatively simple construction, there
are various subtleties that need to be considered if these devices
are to be applied to a system design correctly.

Embedded
Modems
The
modem made its first real appearance in the summer of 1960 with
AT&T's Bell 202 data set. Since then it has evolved in sophistication
to pass data over the telephone dial-up network at the highest
speeds. The «last" of the modem standards, ITU-T V.92, was published
in 2000, achieving maximum upstream data rates of 48,000bits/s
and up to 56,000bits/s on the downstream. This article by Keith
Chu from Teridian proves that these capabilities opened up the
Internet to the world at large.

Routines
directly measure microcontroller-bus clock
The
Freescale HC08 and newer HCS08 microcontroller families have
versatile peripheral modules. Their clock generators are no
exceptions. Once you write the bus-clock-initialization routine,
you may want to verify that the bus is running at the speed
you intend before moving on to the rest of the project. This
Design Idea by Kerry Erendson from Bulova Technologies presents
routines that output a square wave at exactly one-tenth the
bus speed on any I/O port.

Circuit
for measuring motor speed uses low-cost components
This
Design Idea by R
García-Gil, J Castelló, and JM Espí, Escola Tècnica Superior
d’Enginyeria, University of Valencia, Spain uses
a microcontroller, a 16x2-key LCD, and a rotary encoder to measure
and visualize the speed of a motor. You measure the rotor speed
of the motor using an incremental encoder coupled to the motor
shaft, which provides quadrature pulses with a frequency proportional
to the rotor speed.

Worldwide
Ethernet Switch Market Analysis
Ethernet
switch devices come in many sizes, shapes, speeds, and levels
of intelligence. However, the common denominator among all these
options has been growth. The overall Ethernet switch market
grew steadily in 2006. That upward trend is expected to continue
over the next five years. This report by Instat covers the entire
Ethernet switch market with detailed market shares and forecasts
for each major segment.

Embedded
Systems Design, by A. Sangiovanni-Vincentelli and A. Pinto
This
book will serve as an upper division/graduate level textbook
or a reference book for practitioners and researchers in Embedded
System Design. It is based on a novel methodology (called Platform-Based
Design) and toolset (developed at UC Berkeley over the past
15 years) that is foundational in its approach and has demonstrated
effectiveness in numerous engineering domains, ranging from
integrated circuits to telecommunications to automotive. This
book describes a new design science to address the challenges
posed by the heterogeneity intrinsic to modern system integration.
