There Are No Blueprints-Moving away from "Programming Above All Else"
With a shift from "writing a program" to "drawing a design," conceptions of software development are set to change. If we continue with the traditional system of development centered on source codes, further emergence of numerous quality issues is inevitable. But if we switch to the model base development system centered on design drawings, it will become easier to improve quality, which should also raise development efficiency.

"Very Low Pricing" Creates the World for Information Terminals
Taiwan has grown into a worldwide development and manufacturing base for electronic appliances, particularly PCs, mobile phones, and LCD monitors. But now, car electronics is set to take over. A car electronics exhibition held in mid-August 2006 was bursting with automotive devices that made use of IT originally developed for household appliances.

Asynchronous LSI's with No Need for Clocks Allow the Creation of a Development Environment that Makes Design Easier
Handshake Solutions, an operations division of Philips Electronics, has joined together with ARM to develop the ARM996HS 32-bit CPU core, which is based on asynchronous digital circuit technology and does not use a clock signal. Compared to synchronous digital circuits, which do use a clock signal, asynchronous digital circuits, in which electricity is in the main used only by circuits required for the performance of calculations, have the advantage of greatly reducing electricity consumption. In the design, the asynchronous LSI development environment developed by Handshake Solutions was employed. The new CPU core also has the special feature of allowing use in parallel with the EDA tools of a synchronous LSI and mounting of asynchronous digital circuits using a standard cell library. The increased circuit area, which has been cited as a drawback of asynchronous digital circuits, has also been overcome. This article explains the development environment together with the features of the ARM996HS.

Triaxial Acceleration Sensors
Triaxial acceleration sensors, which can measure acceleration in all three of the X, Y and Z axes with a single element, have begun to be adopted in a wider range of applications. In the field of consumer goods, they were first used to protect the HDDs of portable music players and notebook PCs against being dropped, and their price fell when they began to be used in mobile phones, the controllers of game consoles, and other devices. The models in focus here are the MEMS sensors which detect low levels of acceleration and are suited to miniaturization. Further expansion of applications is likely from 2006 into 2007, when the current price of around 200 yen per unit approaches 150 yen.

Interactive Interface Functionality for Next Generation Optical Disks (Part 3):
Blu-ray Java Allows Full Control of AV, However, It Won't Accept Improper Alterations
Using Blu-ray Java, which realizes interactive interface functionality through Blu-ray Discs, users can use already stored audiovisual content and create original cuts or add or update content. Here, we look at the audiovisual playback control functions, virtual package functions, and security functions which support actions of this kind. (By Naoki Asakawa, Nikkei Electronics)

US Measures to Comply with the RoHS Order Move Slowly
The RoHS directive, which bans the use of hazardous substances, came into effect in the European Union on July 1, 2006. However, many US companies are still unclear about this regulation. While industry associations have issued documents announcing measures against the use of lead and other steps, there are many firms whose RoHS directive compliance measures are still at the planning stage.

The Start of the IPTV Standardization Process (Part 3): Guarantying a Fixed Quality Level over an IP Network
In two previous articles we have focused on three of the four elements required to realize an IPTV service: guaranteed uniformity of the rebroadcast signal, guaranteed anonymity, and methods for restricting the service area. This final article looks at methods for guaranteeing steady service quality.
