    The data rate of the dynamic random access memory (DRAM) interface has been greatly increased to reduce the performance gap between the DRAM and the central processing unit (CPU). The data rate of double-data rate (DDR) synchronous DRAM (SDRAM) is now exceeding 266 Mb/s/pin while the packet-based RAMBUS DRAM is offering up to 1066 Mb/s/pin data rate. The difference in the data rate is mainly due t... View full abstract»

    Designing hardware and software in isolation no longer provides good solutions for complex embedded systems. Hardware-software codesign (HSC) promises an integrated approach in which hardware and software are designed in parallel. CAD environments, employing the tenets of HSC, are being developed to provide a cost and time effective solution. As a result, system engineers must become knowledgeable... View full abstract»

    Electric substations are facilities in charge of transform the voltage into safe and effective energy for the final consumers. This operation has to be carried out with enough quality assurance and without damaging the equipment. The associated cost to ensure this quality and security is high. Automatic mechanisms are used, however, they mostly operate under an individual's control and use the pro... View full abstract»

  • Power systems and harmonic factors

    Publication Year: 2001, Page(s):10 - 12
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (97 KB)

    Harmonic currents and distortions in power systems are a natural progression in society's use of electrical equipment. A proliferation of harmonics can cause problems-some severe. However, the benefits we receive from electrification far outweighs the downside to this problem. There is an increased awareness among equipment designers, manufacturers, and users for the need to reduce power system ha... View full abstract»

  • GaAs FETs [microwave devices]

    Publication Year: 2001, Page(s):35 - 37
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (89 KB)

    The field effect transistor (FET) at microwave frequencies using GaAs has been a cornerstone of research in solid state microwave devices for the past 30 years. It is an established item in the microwave systems of today in such applications as low noise amplifiers, mixers, oscillators, power amplifiers, switches and multipliers. Indeed, many microwave systems would not be possible at their presen... View full abstract»

    Conversion algorithms and arithmetic procedures for a (-1 + j)-base binary number allow a given complex number to be represented as one unit. This should simplify the operations involving complex numbers in today's microprocessors. With the division process secure, we can implement the usual algorithms for calculating functions and processes such as logarithms, exponentials and trigonometric funct... View full abstract»

    Given the difficulties encountered by the state of California in deregulating their electric power industry, many people are questioning the wisdom of such a move. To better understand the motivation behind deregulation, the author looks at the cost of energy nationwide in the United States. For example, she considers some of the regional energy costs from August 2001 View full abstract»
