Performance of Steel Stud Walls Subjected to Blast Loads

Construction trends have brought about an increase in the use of cold-formed steel studs in Air Force facilities. These steel stud walls have significant potential for mitigating large blast events. The current state of steel stud research, however, has not addressed all the variables that can influence the behavior of typical wall systems. As a result, there is a research gap that exists in the blast-resistant design of conventional steel stud wall systems.

12-Volt System with Mini-ITX Motherboard

ITOX (East Brunswick, NJ) has partnered with Systium® Technologies to introduce the Model 132 “mini” series 12-volt system utilizing the ITOX NP101-D16C Mini-ITX motherboard. The Systium Model 132 “mini” series system platform is designed for cost-sensitive applied computing and x86 embedded systems applications requiring high-quality, long-life modular computing solutions. This is particularly applicable to medical electronics, industrial control, security and surveillance, telecommunications, ATM/POS, digital signage, gaming, and kiosk systems fields. The motherboard utilizes the 45nm 1.6 GHz Intel® AtomTM N270 processor with Intel 945GSE Express chipset and ICH7M I/O controller hub. The platform exhibits a thermal design power of less than 15 watts, delivering higher performance-per-watt than previous platforms. A single 12 VDC power input also reduces overall system configuration and operating costs.

Ternary Content Addressable Memory

Renesas Technology America (San Jose, CA) now offers the TCAM (Ternary Content Addressable Memory) Series of memory products to enable high-speed packet processing for networking equipment such as routers and switches. The first product in the series is the R8A20410BG TCAM, which has a capacity of 20 Mbits and delivers high-speed search performance of up to 360 MSPS (mega-searches per second)/Table. TCAM memory cells can store three data states: 0, 1, and X (“Don’t Care”). It is suitable for applications such as networking equipment because it achieves deterministic, high-speed searches by using simultaneous parallel operation to compare data strings input from an external device with data strings stored in the memory and outputting the matches.

Single-Chip OTN Platform

Zarlink Semiconductor (Ottawa, Canada) has introduced ClockCenter, a platform for high-speed optical transport network (OTN) and communications equipment. ClockCenter synchronous products synchronize “any rate, any port, all the time,” meaning the single-chip solution accepts and generates any frequency (1 kHz to 720 MHz) required to support all communication services delivered over optical and Ethernet networks. The ClockCenter free run products are suitable for designing equipment for a range of applications that have traditionally relied on multiple oscillators, logic converters, and fan outs to time processors, memory chips, PHY chips, and more. The free run clock products allow equipment manufacturers to replace multiple external components with an integrated single-chip device.

Programming Network Processors Made Simple

The telecommunications industry’s continuous strive for higher performance has spurred innovations in processor architectures. The general trend has been to go parallel; adding more cores to a single processor device and then dividing tasks between them. This has resulted in a more complex environment for software engineers to master. But does this mean that the programming of next-generation network processors (NPUs) has to be difficult? Not necessarily.

Designing Solid State Drives Into ATCA-based Platforms

Due to the growth of video on demand (VoD), IPTV media content, and embedded database applications, AdvancedTCA (ATCA)-based storage capacity requirements continue to increase exponentially. In addition, storage requirements have become more complex and varied for ATCA designs that have expanded beyond the central office to include network data center and general data center applications that need to handle a wide variety of server platforms. The advancements and general availability of new storage solutions, particularly solid state drives (SSDs), enables ATCA platform developers to meet the design metrics of a broader range of markets where distributed data storage and management become increasingly required. The continual evolution of SSD storage technology, with its improved capacity, performance, and cost reductions, provides additional opportunities for integrating storage directly into the ATCA platform, allowing new designs to gain the benefit of high performance and availability provided by ATCA-based systems.
