SHF: Small: Low Power System-on-Chip Circuits and CAD

能源影响着社会的方方面面。 由于电子产品无处不在的性质，美国的大部分电能消耗都没有被注意到，这改善和提高了我们的生活水平。 例如，根据美国环保署提交给国会的报告，2006年我们的手机和电脑使用的数据中心的电力成本达到45亿美元-相当于15个发电厂。该提案开发了一种变革性技术，可将电子设备的功耗降低三倍。 该技术的核心是基于应用于集成电路上逻辑和通信元件时序的理论，其中信号可以在给定介质中以光速传播。这笔资金的主要成果将是开发电路、软件（计算机辅助设计）和设计技术，使这种低功耗技术能够从科学实验室转移到商业产品中。 相对时序理论将映射到当前的商业设计和验证流程中，使用形式化的正确性证明进行翻译。 这将使该技术快速商业化。 一个新的超低功耗电路系列将开发详尽的行为调查的基础上。 该系列同样可以是映射到铸造厂使用的当前制造库的技术。 最后，通过设计和制造复杂的片上系统，将功率降低三分之一，以及快速构建商业产品的能力将得到证明。这项工作的主要影响是减少我们无处不在的电子产品所使用的能源。 能源使用的影响具有全球性的影响。 在过去的十年里，电子产品的能源消耗呈指数级增长。 集成电路所消耗的能量已经对经济和环境造成了相当大的影响，其CO_2排放量也是影响的一个重要因素。 该研究将继续提高美国的技术领先地位和竞争力。 向工业界的技术转让还将创造数百个就业机会，并提供应税收入。 这项研究得到了业界的大力合作和支持，包括与德州仪器、英特尔、Mentor Graphics和ON Semiconductor的直接互动。 这项工作建立在犹他州大学强大的研究基础之上。 该大学在扩大工程学生人数方面有着良好的记录。

Energy impacts all aspects of society. Much of the U.S. electrical energy consumption occurs unnoticed due to the ubiquitous nature of electronics that improves and enhances our standard of living. For example, according to the US EPA Report to Congress, the electricity costs of data centers used by our cell phones and computers amounted to $4.5 billion dollars in 2006 -- the equivalent of 15 power plants. This proposal develops a transformative technology that reduces the power consumption of electronics by a factor of three. The core of the technology is based on a theory applied to the timing of logic and communication elements on an integrated circuit, where signals can travel up to the speed-of-light in the given medium. The primary result of this funding will be to develop circuit, software (computer-aided design), and design technology that will enable this low power technology to be moved from scientific laboratories into commercial products. The relative timing theory will be mapped onto the current commercial design and validation flow, using formal proofs of correctness for the translation. This is what will enable fast commercialization of the technology. A new ultra low power circuit family will be developed based on exhaustive behavioral investigations. This family can likewise be technology mapped to current fabrication libraries used by the foundries. Finally, a factor of three reduction in power as well as the ability to rapidly build commercial products will be demonstrated through the design and fabrication of a complex system-on-chip.The primary impact of the work is the reduction of energy used by our ubiquitous electronics. The impact of energy usage has worldwide ramifications. Electronics have had an exponential growth in energy consumption over the last decade. The energy consumed by integrated circuits already pose a considerable impact on the economy and environment in terms of CO_2 emissions. The research performed by this grant will continue to improve U.S. technology leadership and competitiveness. The technology transfer to industry will also create hundreds of jobs and provide taxable revenue. This research has significant collaboration and support from industry, including direct interactions with Texas Instruments, Intel, Mentor Graphics, and ON Semiconductor. This work builds on the strong research foundation of the University of Utah. The University has a strong record of outreach to increase the engineering student population.
