Industry View -- Exclusive to Electronic Design UPDATE ********************** Critical Elements Of A Product-Line Software Strategy By Norm Delisle, Engineering Vice President, Foliage Software Systems Over the past couple of years, the software industry has started focusing considerable attention on product-line architectures. A product line is a closely related family of products intended to serve several segments of the same overall market. The product-line architecture allows the entire family of products to use the same software framework. In other words, there is a high degree of common software (and hardware) used across the product line. At the same time, the common software framework facilitates development of the variety of unique features required by each individual product. Product developers have been using product-line concepts informally for well over a decade. It is not unusual to see a single software framework used in dozens of product models -- sometimes across multiple product lines. Of course, this software reuse strategy is not always entirely successful. A software framework that is not architected to effectively support the range of commonality and variability required by the products it supports will quickly erode, resulting in productivity, quality, and time-to-market problems. Several elements are critical to an effective product-line software strategy: -- Setting Realistic Objectives: You need to start by determining the right mix of products. If the products are too diverse, a single product-line software framework will not be able to support them effectively. Objectives should include level of investment and return-on-investment needed and the timeframe. -- Formulating the Architecture Strategy: The architecture strategy needs to analyze the dominant complexities and architectural drivers across all the anticipated products in the line. It is not easy to predict future product requirements accurately, but most companies can base the projections on their history with these product types and industry trends. -- Developing the Architecture: The product-line architecture will employ organizing principles derived from the dominant complexities and other architectural drivers. Typically, the architecture employs loosely coupled, highly modular software components or services built on top of a rich common software infrastructure. -- Developing the Common Software Components: Before any products can be developed using the product-line software framework, the common components need to be developed. Each component is developed with intra-component commonality and variability mechanisms in mind. In the case of migration from legacy software, the components are typically based on existing code that is reengineered for use in the framework. -- Developing Products from the Product-Line Framework: The product-line framework provides a huge head start when each product needs to be developed. Typically, the commonality and variability mechanisms provided in the framework will help guide the product development effort. In some cases, the framework's reusable components will need only minor enhancements. In other cases, new components can be developed and easily integrated into the framework. -- Substantiating the Product-Line Framework: Sustaining a product-line framework requires an ongoing investment. Typically, the product developers need to be focused on producing the software for their products, and they are not able to invest the extra effort needed to continue to evolve the common framework components. Frequently, a separate product-line support organization is formed with the charter to continue to evolve the framework to better meet product needs and incorporate new capabilities developed by the product efforts. Too often in most companies, engineering decisions are made without full knowledge of the business implications. By the same token, software limitations overly constrain business strategies. A better coupling is needed between engineering and business strategies. A product-line strategy encompasses both realms, resulting in the coordinated, well-orchestrated creation and execution of both engineering and business objectives.

Focus On Embedded Systems ********************** ***DSP Gets TCP/IP Ethernet Stack Texas Instruments' TMS320VC5416 DSP device gains Ethernet connectivity with the addition of the Infinetix Ethernet daughter card. The card delivers TCP/IP support via CMX-MicroNet from CMX Systems. CMX-MicroNet requires only 3 to 20 kbytes, depending on the features included. The package includes a number of TCP/IP application services. CMX-MicroNet pricing starts at $5500, and a free demo version is available upon request. The Infinetix card costs $195.

News -- From The Editors ********************** ***Small-Outline LCD Modules Go Industrial Two new wide-viewing-angle thin-film-transistor (TFT) LCDs target industrial applications. The XGA 12.1-in. LTD121GA0S features a 100-deg. vertical/120-deg. horizontal viewing angle. The VGA 10.4-in. LTD104C11S allows 120-deg. vertical/140-deg. horizontal viewing. The 'C11S measures 278.3 by 209 by 12 mm, and the 'GAOS sizes up at 238.5 by 177.5 by 12 mm. Luminance is 350 and 400 cd/sq. m, respectively, and they consume 7.7 W and 6.2 W, respectively, at 6 mA. The larger display module operates from 3.3 V, while the smaller one operates from 3.3 and 5 V. Available now in sample quantities, the 'C11S goes for $375 each, and the 'GAOS costs $325 each.

The instrument is designed for benchtop or automated test of contact and bonding resistance on a wide variety of components, including switches, connectors, relays, solenoids, fuses, motors, cables, and heating elements. It automatically selects from nine measurement ranges and includes a programmable high/low comparator function and eight sorting bins for pass/fail testing and device categorization. Test setup and comparator/binning information is automatically recalled on instrument power-up. Three measurement speeds allow for varying degrees of accuracy and up to 15 measurements per second. A four-terminal Kelvin connection and automatic zeroing eliminate errors introduced by the test leads. Polarity reversal and pulsed modes compensate for thermal electromagnetic-field effects and errors caused by device heating. The LR2000 costs $2495, which includes an RS-232 interface, a NIST-traceable calibration certificate, and Kelvin test leads. An IEEE-488 interface and handler is optional.

Sales in 2003 were $166.4 billion, up 18.3% from $140.8 billion in 2002. Fourth-quarter revenues were $48.1 billion, up 11% from the third quarter and up 28% year-to-year. "The industry's broad, upward momentum across all product sectors and geographic markets is driving us toward another year of strong, double-digit growth, which is now expected to exceed 19% in 2004," said George Scalise, SIA president. "The wireless sector continues to spearhead growth, but PC shipments also recovered in 2003 to an 11% unit volume increase. We are experiencing a virtual revolution in global consumer markets as consumers adopt new technology and multifunctional smart devices such as camera phones, PDAs, and DVDs." All geographic markets recorded increased sales during the fourth quarter, according to the SIA report. Semiconductor Industry Association ==> http://lists.planetee.com/cgi-bin3/DM/y/eeZh0DJhUf0EmQ07EI0AB ***Eclipse Platform Under New Management Future development of the Eclipse Platform is now in the hands of a not-for-profit corporation, a change from the consortium that was formed when IBM released Eclipse into Open Source. The result is an independent, full-time management organization that will engage with commercial developers and consumers, academic and research institutions, standards bodies, tool interoperability groups, and individual developers. It also will coordinate Open Source projects. A set of councils -- Requirements, Architecture, and Planning -- will guide the development done by Eclipse Open Source projects. With support from more than 50 member companies, Eclipse already hosts four major Open Source projects that include 19 subprojects. All technology and source code provided to the ecosystem will remain openly available and royalty-free.
