XML Changes Embedded Software—a Key to Improve Development
Efficiency . . . p.
51
Markup languages such as XML seem likely to be increasingly used to develop graphical
user interfaces (GUIs) for embedded devices, which means users will be able to
manipulate such devices via an operation screen defined by markup language. Markup
language looks set to spread throughout the field of embedded software, starting
with mobile phones.
Competition Between IEEE802.11n and UWB Breaks Out for Wireless Interface
. . . p.
61
In the midst of competition over standardization between two rival technologies,
IEEE802.11n is improving in terms of low power consumption and high data speed. With
both of the technologies have the characteristics that ultra wideband (UWB) excelled
in, the gap between them has become quite small. The two wireless interface
technologies are now facing up against each other.
Cover Story
Home Electrical Generation Starts Up . . . p.
89
Electrical generation in homes is here at last. Electrical generation systems
that are heading down the road toward becoming popular include fuel cells and
gas engine powered cogeneration systems, as well as solar cells.
Improving
generation efficiency and achieving low cost will be the key to raising the number
of units installed. Manufacturers of energy, housing, home electronics
and automobiles are all taking various steps to seize the new business opportunities
in this fledgling market.
(Part 1)
Electrical generation in homes is here at last. Just as fuel cells, highly
anticipated as being a trump card, are finally being sold to the general public,
gas engine powered cogeneration systems are showing unexpected promise for popular
use.
The rise of this new market puts a sparkle in the eyes of energy,
housing, home electronics and automobile manufacturers. Not only do home
electrical generation systems cut heating and electricity expenses, but by creating
new value that will make everyone want to own such a system, and by expanding
the number of households able to install one thanks to their low cost and high
efficiency, the use of home electrical generation will become widespread.
(Part 2)
In addition to cogeneration systems using gas engines, monitored sales of polymer
electrolyte fuel cells (PEFCs) as a household energy source are under way. There
is also talk of a practical application in 2008 of solid oxide fuel cells (SOFCs),
which surpass PEFCs in terms of electrical generation efficiency. Manufacturers
of solar cells, as well, are aiming to achieve electrical generation costs similar
to those of commercial power supplies by 2010.
Whether an electrical generation
system is able to survive in a household electricity market now swamped by competition
depends entirely on its ability to lower costs.

Learning Methods to Control Power Supply Voltage from 3 Examples;
Treat the LSI and Board as One . . . p.
115
Many device and LSI engineers are tormented by power supply voltage, the fluctuations
of otherwise constant power supply and ground voltage in a printed circuit board
(PCB), and their attention is turning to power supply simulation technology.
The
leader in adopting this simulation technology, Fujitsu Limited, reveals details
of its independently-developed power supply voltage analysis system, using actual
examples of applications to devices and LSI, including storage devices, digital
consumer electronics, and even microprocessors for embedded devices. The
company’s main feature is the methodology it created for integrating PCB
and LSI power supply behavior, taking advantage of the combined strengths of
its device and LSI departments.
As a result, Fujitsu managed to shrink
development time and reduce costs for its own products, and this even led to
it offering engineering and consulting services to other companies.

Including HDMI Compatible Thin Film Devices, 1210 Common Mode Filters
for Mobile Devices Appear . . . p.
130
The utilization of High-Speed Serial Interface (HSSI) is on the rise with the
advent of high-definition video and the miniaturization of mobile devices. HSSIs
enable transmission of large volumes of data using a small number of buses.
The
task faced is that measures to combat noise are increasingly important to ensure
the error-free transmission of data. Here we look at common mode filters,
which are indispensable in HSSI design. We look at products for low-voltage
differential signaling (LVDS), digital visual interface (DVI) and High-Definition
Multimedia Interface (HDMI), which are employed to transmit video signals, as
well as for the USB 2.0 or IEEE1394 specifications used widely in personal computers,
mobile phones, and digital cameras.
The number of membrane and layered
filters for mobile devices that are smaller than 1210 size is on the rise. Recently,
0806 and 1005 size products have appeared.

Applying Optical Technologies to Measurement and Communications
(Part 1) . . . p.
135
By using a photonic electric field sensor, developed by combining elemental technologies
in the rapidly progressing optical communications field, signals passing through
printed circuit boards and the inner nodes of LSI can be measured at unprecedented
levels of accuracy.
This first installment mainly explains the fundamentals
of the sensor and its superiority over conventional measuring technologies.
“Side Channel Analysis” Is a Real Threat to Encryption (Part
1) . . . p.
141
Coding research has shifted from the early stages in mathematics (algorithms)
to engineering (product mounting), and now to physics.
In other words,
attention is focusing on the side channel analysis of codes, through measurement,
for example, of the leakage of electromagnetic waves from products.
The
first article in this series introduces the fundamental principles and industry
trends.
