Keep two watchwords in mind when you
head to next month’s Embedded Systems
Conference—more and better. Scheduled
for April 14-18 at the McEnery Convention
Center in San Jose, Calif., this year’s
show will reveal a number of incremental
improvements as companies deliver systems
based on established standards and
product lines. For example, Intel will offer its latest Xeon processor
chip sets with an eye on power management.
The tech sessions will remain a big part of the conference,
which are a major draw for most engineers. Mainstays like
“DSP Demystified” and “C (and C++) Gotchas” will return.
You’ll also find a larger concentration in areas such as power
management with “Let Sleeping Chips Lie: Programming
for Low Power” and security in “Seven Steps for Developing
Secure Mobile Devices.”
The “Build Linux Applications with the MicroBlaze Soft
Processor” session will highlight the uptick in general FPGA
usage. Likewise, strong interest continues in areas such as
operating systems and development frameworks. For instance,
there’s a session on “Eclipse—Up Close and Personal.”
A few of you may sit in on these sessions simply to polish
your resume. On that note, you can expect a good bit of traffic
at the ESC Career Fair, given the current economic forecast.
Of course, the fair is a panoply of the latest technology, and
that includes plenty of new software packages.
SAN JOSE SOFTWARE
LynuxWorks will showcase its LynxSecure separation kernel.
Separation kernels provides a robust environment where mixing
secure and non-secure operating systems (OSs) is
common. It allows legacy systems
to run side by side with new
application platforms.
Hypervisor
technology offers isolation while taking advantage of the virtualization
and multicore capabilities of the latest processor chips.
LynxSecure supplies a base for LynuxWorks’ LynxOS
real-time operating system (RTOS), which now can provide
time-space partitioning and OS virtualization. These features
resemble those of other RTOSs that will be on display, such as
Green Hills Software’s Integrity and its Padded Cell Secure
technology—same idea, different name.
Security will take up a larger chunk of the announcements
at ESC, partly due to customer demand and partly due to the
need to build up the infrastructure to support networked devices.
Also, developers are starting to understand and demand this
type of support.
At the lower end of the spectrum, attendees can take a gander
at Microsoft’s .NET Micro Framework 2.5. This platform
targets midrange 32-bit platforms with a new low footprint of
128 kbytes of RAM and 256 kbytes of flash. This includes a new,
native TCP/IP and room for at least one application. Plenty of
single-chip solutions now can address this platform. The number
goes even higher for those that utilize external memory.
This latest incarnation of the .NET Micro Framework adds
support for the Devices Profile for Web Services (DPWS),
which is found on .NET’s larger siblings, including Windows
CE and Windows XP Embedded. DPWS allows network
devices to
locate each other and collaborate, as well as subscribe
to events.
Of course, an even broader range of processors supports
the .
NET Micro Framework, including chips from Atmel
and NXP.
These ARM-based solutions are an ideal fit.
Also in
the ARM space, Hitex Development Tools offers its support for STMicroelectronics’ Cortex-M3-based STM32
microcontroller (Fig. 1). The development kit includes the
HiTOP development environment. Integration with the Tasking
VX-compiler is available as well.
The development environment features the DashBoard graphical
user interface, which lets users configure the device and view
the effects of an application while it’s running. The evaluation
board has interfaces for USB, CAN, USART, and IrDA, plus an
optional extension I/O board.
You may also do well to stop by the Eclipse PluginFest 2008
and see the latest Eclipse-based development tools. This event,
which overlaps ESC, will be held at Wind River’s offices in nearby
Sunnyvale, Calif., April 16-17.

BOARDS AND SYSTEMS
Quite a few boards and systems will debut at ESC, including a
new platform from Diamond Systems. The Neptune and Chameleon
combine to form a modular system with PC/104 expansion
capabilities (Fig. 2).
The Chameleon-based board has an EPIC form factor. Its
connector interface plugs into the Chameleon, allowing for easy
customization without modifying the main board or module. The
Neptune ETX single-board computer attaches to the bottom of
the Chameleon.
The approach builds on standard interfaces while providing
access to a 250-kHz, 16-bit, autocalibrated analog-to-digital
converter (ADC) with 32 single-ended or 16 differential analog
inputs, as well as a 2048-entry FIFO, a four-channel 12-bit
digital-to-analog converter (DAC), the 8-bit I/O ports, and a pair
of timers. The Chameleon also provides access to the Neptune’s
gigabit Ethernet, IDE, floppy, parallel, LCD, and TV-out ports. It
offers VGA, audio, and 10/100 Ethernet, plus six serial, four USB,
and two PS/2 ports off the connector adapter as well.
Keep an ear out for announcements from the Small Form Factor
SIG (SFF-SIG). The group is addressing the small modular
and stackable board arena, where standards have been slow to
emerge lately. VIA Technologies will show off a form factor based
on its Pico-ITX line, which uses a new expansion system.
Known as Stackable Unified Module Interconnect Technology
(SUMIT), the system is based on a high-density, bladed
Samtec connector. The connection supports PCI Express and
USB ports, which allow support for ExpressCard, as well as SPI,
I2C, and the LPC bus.
For a more systems-oriented approach, check out Applied Data’s
fanless netCast Player HD. It brings IP set-top-box capabilities to
automotive entertainment systems and digital signage applications.
Moreover, it can handle video resolutions up to HD 1080p. The
Linux-based system supports wired or wireless networks in addition
to features like touchscreens and password protection.
Planar Systems’ 12-in. LX1201PTI Mariner Touch Monitor
presents a more basic system (Fig. 3). This monitor/touchscreen
targets marine environments. Planar also will present its 24-in.
LB2411W Widescreen Open-Frame Kiosk LCD system.
FPGAS AND MICROS
Expect to see a whole new crop of FPGAs and chips at ESC.
Altium will display its FPGA-based Innovation Station, a reconfigurable
NanoBoard hardware platform (Fig. 4). The development
platform is great for prototyping and clean enough to be deliverable.
The boards include a number of case options. In this setup,
developers start with Altium Designer and the Desktop Nano-Board. The design then can move to
a deployment NanoBoard platform
like the Innovation Station. This
looks to be a hot item.
In addition to FPGAs, the
show will host an array of new
microcontrollers. Silicon Labs will reveal
a 25-MHz, mixed-signal, 8051 powerhouse that
runs on as little as 0.9 V, enabling it to run off a single
AAA cell. The C8051F9xx line is designed for batteryoperated
applications.
Its low power requirements, on-chip dc-dc converter, and analog
peripheral set suit it for sensor applications, low-power portable
multimedia devices, and general control applications. Peripherals
include a 32-channel, 10-bit ADC; two comparators; a UART; a
pair of SPI ports; SMBus support; and 24 I/O ports.
Microchip will unveil its 40 MIPS dsPIC33F, which fits in a
6- by 6-mm package (Fig. 5). It packs up to 128 kbytes of flash
and 16 kbytes of RAM into a chip that starts at $3.67. The device
also includes a dual-channel, 16-bit DAC plus a 12- or 10-bit
ADC. On top of that, there’s eight-channel direct memory access
(DMA), a pair of UART/LIN/IrDA ports,
two
SPI ports, an I2C port, and a controller area
network (CAN) port. The motor control support
includes pulse-width modulators (PWMs) and
power-factor-correction (PFC) PWMs, plus a pair of
quadrature
encoder interfaces.
"MODULES, WIRELESS, ETC.
DLP Design will showcase a few new modules, including a
UHF RFID reader and a 900-MHz transceiver module that’s
designed to compete with 802.15.4 and ZigBee (Fig. 6). The
module incorporates its own protocol and targets low-power applications.
The company
will also have a temperature/humidity acquisition
system on hand that logs data to a server and can send e-mail
notifications.
Also in the wireless space, Digi International’s Drop-in Networking
line will be on display, including some new products. For
example, the ConnectPort X2 gateway supports ZigBee and Wi-
Fi. The company’s XBee adapters and Watchport wireless sensors
will be on display, too. For wider ZigBee network coverage, check
out Digi International’s XBee Wall Router unit.
As usual, ESC will have hordes of attendees and new products
for them to peruse. The announcements covered here represent
just the tip of the iceberg.
