    New cellular neural network chips, with stored-program capability and analog-and-logic architecture, are poised to challenge all-digital processing. In this article, we highlight the key ideas leading to the CNN Universal Machine, using simple circuit interpretations. We also illustrate the system, software, and application aspects View full abstract»

    In the light of the many changes taking place in the printed circuit board industry, how does a printed circuit board company reduce manufacturing cost and still beef up quality? This article examines this question and how to reconcile all the relevant considerations, including increased complexity of product, market demands for lower prices and higher quality, and the need to bolster return on assets View full abstract»

  • Designing for wireless LAN communications

    Increasingly, the wireless communications industry has been moving toward networks that communicate over smaller areas at lower power levels. Until recently, most wireless communications were in the form of satellite transmissions. In the early 90s, the mobile cellular phone industry exploded and work has begun on short range wireless networks to send data. BBN's BodyLAN project proposes to take this progression one step further, by lowering the power consumption for extremely short range systems by more than an order of magnitude. Designing a low power system of this type requires an understanding of the capabilities of VLSI technology, the interrelation between hardware and software techniques, and some knowledge of radio frequency propagation. In this article, we discuss the engineering pitfalls to avoid, and the trade-offs inherent in such a design, using our experience with BodyLAN as a starting point for further development of such a system View full abstract»

    In this article, Brian Antao of Motorola Inc., presents an overview of the state-of-the-art in analog modeling and hardware description languages. The emphasis is on higher-level circuit and system behavioral models for modeling complete analog and mixed analog-digital systems. An essential component required for this level of modeling is a Hardware Description Language (HDL) to encode the models in a consistent manner which can be later simulated as well as used for design documentation. Hardware Description Languages are a prominent feature of the digital design process, and the newer generation of the mixed-analog-digital systems require compatible hardware description language support that provides for the analog sections. Two popular digital HDLs are VHDL and Verilog. To provide natural extensions to these existing digital standards, analog hardware description language (AHDL) standardization efforts are underway to develop analog extentions to VHDL, called VHDL-A, and to Verilog, called Verilog-A View full abstract»
