Code Base Growth, Safety-Critical Requirements Driving Static Analysis Market
Recently published research by VDC Research indicates that embedded software engineers using a static analysis tool are working on projects with significantly larger average numbers of in-house developed lines of software code than developers not using a static analysis tool. VDC considers static code analysis tools to include solutions ranging from Lint-based syntax parsers to standards’ compliance checkers to tools using more formal methods for verification.
With the overall embedded code base growing at a rate near 10%, VDC expects that an increasing number of development teams may look toward static analysis tools as a means to ensure code quality and functionality.
The difference between the average code bases of these user groups can also serve to benchmark the typical code base sizes needed for a project team/company to be considered a legitimate candidate for a commercial static analysis tool. However, application classes tending to have requirements that are more safety- or security-critical in nature embrace static analysis tools at a higher rate; previously, code base size and complexity alone would normally drive development teams to consider additional testing methodologies.
For example, surveyed static analysis tool users currently working on a project for the military/aerospace industry (which also accounted for the highest percentage of the total amount spent on embedded software static analysis tools in 2007) reported a median of 22,500 lines of in-house developed code as compared to 45,000 by the overall static analysis tool user population.
Although VDC believes that an increasing number of development teams will look toward static analysis tools as a software development best practice, the escalating importance of software quality will generate a growing demand for comprehensive testing solutions that can also provide tight integration with dynamic testing tools as well as with other complementary application lifecycle management tools.
LonWorks Networking Technology Becomes a Series of ISO/IEC Standards
LonMark International, a non-profit, member-driven standards development and industry trade association supporting the LonWorks control-networking technologies, has announced that the voting members of the Joint Technical Committee (JTC 1) of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) have formally approved LonWorks control-networking technology as ISO/IEC 14908, Parts 1, 2, 3 and 4.
This ratification will enhance the adoption and usage of this technology within the worldwide controls market and specifically in building control. While LonWorks is also used in many other markets, such as outdoor lighting, transportation, utility, process control and home automation, the majority of the over 100 million installed devices have been installed in or around buildings projects.
The four parts of the standard set comprise the core protocol; the twisted-pair, free-topology-wiring transfer medium; the powerline transfer medium; and the use of the Internet Protocol (IP) as a tunneling transfer medium, respectively.
LonMark International plans to host an educational seminar and press conference on ISO/IEC standardization at the upcoming AHR Expo in Chicago on January 27, 2009. Interested parties can find more information about these events and the standards on the LonMark Web site at www.lonmark.org. Additional white papers discussing the ISO/IEC standard and LonWorks will also be available on the LonMark Web site.
IPv6-Based PhyNet WSN Chosen for Emergency Communication System
The PhyNet wireless sensor network (WSN) by Arch Rock has been selected by HITEC Luxembourg S.A. for use in its Nomadic Satellite Communication System (NoSaCo), developed for natural disasters and other public safety situations. NoSaCo with PhyNet underwent a “dress rehearsal” in May 2008 at the ING europe-marathon Luxembourg, an annual event attended by some 4,000 runners and close to 100,000 spectators.
NoSaCo, part of HITEC Luxembourg’s Public Safety Suite, was designed as a rapidly deployable ad hoc, high-performance communication system for use in emergency scenarios where existing infrastructure has been destroyed or rendered unreliable. The system uses various wireless technologies, such as satellite, Wi-Fi and short-range radio, as well as video and voice communication and sensor networks that can monitor critical information on-site and transmit it quickly over the Internet to those in charge of rescue operations.
The NoSaCo system was already well into the definition phase when, in the fall of 2007, the development team learned about PhyNet. The PhyNet architecture appealed to the NoSaCo team because it was low power, easy to deploy and based entirely on the ubiquitous Internet Protocol (IP)–and specifically on IPv6, the newest and most scalable version of IP. Furthermore, PhyNet was the first multi-tier WSN to address large, geographically dispersed applications by forming multiple highly resilient IP-based sensor networks that users could manage centrally as part of the overall IP infrastructure. The key to this architecture was a new kind of router that formed an internetworking backbone between an individual WSN and its server-hosted applications, allowing information to be monitored miles–or even thousands of miles–away from their control and management functions.
One Stop Systems Purchases Ciprico Storage Product Lines
One Stop Systems has announced that it has purchased the exclusive manufacturing rights to Ciprico’s MediaVault, Talon4 and DiMeda product lines. In addition to assuming the existing product order backlog and inventory, One Stop Systems will fulfill new orders for products from customers and distributors, will manufacture the products, including material procurement, fabrication, assembly and test, and will provide technical support to customers and distributors.
The MediaVault products are direct attached storage devices used in commercial applications such as radio and television broadcasting and video imaging. They include a 5-drive desktop RAID array (OSS-4105), often paired with Apple systems, a 10-drive rackmount version (OSS-4210) and a 40-drive RAID array (OSS-4440). All of these are offered in SCSI320 or Fibre Channel interfaces. In addition, an 8 and 16 drive PCI Express-based RAID array (OSS-5108, OSS-5116) provides even higher bandwidth data storage. The Talon4 meets the stringent standards for shock, vibration, and severe environmental and temperature changes typically found in airborne, shipboard, fixed and mobile ground-based installations. The Talon4’s dual controllers meet the Storage Bridge Bay (SBB) 2.0 specification.
The DiMeda NAS (network attached storage) appliance (OSS-1716) offers performance levels reaching 700 Mbytes/s supporting high-performance file sharing and video streaming applications. The 1716 supports both SATA and SAS drives and offers a greatly enhanced RAID feature set. It is ideally suited for the digital cinema market as well as any application where multiple systems are accessing high-speed data transfers.
Alereon Receives FCC Modular Certification for Worldwide Wireless USB Half-MiniCard
Alereon, a Certified Wireless USB technology company for Ultra Wideband (UWB) WiMedia solutions, has announced it has received FCC modular certification for its AL5708 Worldwide Wireless USB Half-MiniCard. The AL5708, which provides Wireless USB connectivity for laptops and desktop PCs, is the first and only FCC approved Wireless USB embedded notebook solution for use in UWB bandgroups one, three and six.
Alereon’s AL5708, which is PCI Express (PCIe) type H2 compliant, is based on the AL5000 family chipset that covers the entire UWB spectrum from 3.1-10.6 GHz. In addition, the AL5708 is the only solution to date that supports bidirectional, isochronous data transfers both in and out allowing manufacturers to support common consumer devices such as USB speakers and Web cams.
The AL5708 Half-MiniCard is the fifth Alereon product that has received FCC modular certification for Band Groups one, three and six, further expanding the rapidly growing portfolio of Wireless USB solutions, both on the host and device side, which Alereon will bring to market in early 2009. Alereon also received PCI Express V1.1 certification from the PCI-SIG for the AL5350 Worldwide PCIe WiMedia/UWB Baseband and MAC, the base chipset used in the AL5708 Half-MiniCard.
