SOC(System On Chip)将原来分立器件实现的CPUs、DSPs和存储器等模块整合在一个单芯片内,这种设计方法使得外围的IP模块的复用变得非常重要.而复用的IP模块必须嵌入到SOC中进行系统验证后才能使用,系统功能验证通常使用原型机的验证方法.该文论述了汉芯SOC的FPGA原型机验证环境的实现方法,以及如何使用串口建立起PC机与原型机的通讯.原型机验证中的一个普遍问题是ASIC设计代码不能直接映射到FPGA,否则会造成FPGA实现的硬件效率低,甚至时序不能满足从而导致验证失败,该文以门控时钟为例,对这种代码的转换提出一种可行的方法,并对转换前后的性能做了对比.最后,以一个常用的IP模块为例,对复用IP模块的系统原型机实时验证进行技术研究与探讨. 相似文献

It has been noted in the past that economically sound, environmentally preferable life extension modes such as remanufacturing and recycling have special characteristics that complicate the management of their production, logistics and associated operations. This paper considers these complicating characteristics from the perspective of the nine different modes of product life extension. In doing so, a framework and guide is provided to what issues, resource requirements and management capabilities are required for specific life extension modes. This framework provides guidance to practitioners and academics on commonalities between different product life extension modes, thereby assisting practitioners in leveraging current internal skills and capabilities and researchers in determining the generalizability of research. 相似文献

This study aims to evaluate the performance of ozone treatment for removing N-nitrosamines from reverse osmosis (RO) concentrate in water recycling applications. In the absence of any N-nitrosamine precursors, the destruction efficiency of N-nitrosamines was dependent on their molecular weight or the length of the alkyl chain in their molecular structure. Experiments conducted with RO concentrate showed that ozonation could lead to the formation of N-nitrosodimethylamine (NDMA) and N-nitrosodiethylamine (NDEA), resulting in an increase in concentrations of these N-nitrosamines. Nevertheless, ozonation was effective for destruction of N-nitrosamines with molecular weight greater than that of NDEA (102 g/mol). 相似文献

The evolution of the Yangtze Riverfront Park in Wuhan, China highlights what many waterfront cities around the world are facing with respect to converging forces of urbanism, growth, resiliency, and ecological degradation. This site emphasizes why the public realm is a critical component in addressing all of these often-conflicting issues. By re-envisioning the 16-kilometer-longriverfront landscape, Wuhan is creating a new paradigm for its parks by embracing flooding as a regular occurrence and a driving force in the shaping of its public realm. This strategy of working with Nature and not against it allows visitors to understand and appreciate the river’s complex dynamics. The proposed development of the Yangtze Riverfront Park aims to harness the power of natural processes to nurture a rich regional ecology, improve ecosystem services, and enhance public health and recreational amenities. Informed by an extensive public engagement process and crowdsourced data, the redesign of the park reinforces Wuhan’s cultural identity by preserving decommissioned industrial infrastructure and other artifacts along the river that symbolize the city’s industrial legacy and urban history. The vision for an updated Yangtze Riverfront Park strives to create a socially inclusive, culturally relevant, and ecologically meaningful waterfront that emphasizes Wuhan’s identity of living authentically with an everchanging river. 相似文献

本文介绍了西方关于建筑再利用的理论研究和教学概况,以期为国内更好地理解建筑再利用问题以及将来开展相关研究、教学和项目实践提供些许参考。本文第一部分介绍了建筑再利用的理论研究,从建筑学领域和遗产保护领域这两个方面分开阐述,建筑学领域关于建筑再利用的理论研究主要分为类型学、技术派、建筑策略和室内设计等方向,遗产保护领域关于建筑再利用的专门讨论是近几年才开始的,主要包括适应性再利用、可持续再利用和共同演变式再利用等方向。第二部分介绍了建筑再利用的教学情况,首先以米兰理工大学为例介绍了建筑学科下关于建筑再利用的专业课程教学,接着以美国罗德岛设计学院和比利时哈瑟尔特大学等高校为代表介绍了关于建筑适应性再利用的专业硕士培训项目,最后介绍了欧盟关于现代主义建筑再利用以及其他高校关于建筑再利用的硕士培训项目。 相似文献

Concrete formwork is a labor-intensive and time-consuming operation. Many modular formwork systems have been developed to automate the process. Such systems improve the productivity as well as the cost-effectiveness of the operation. However, proper planning for the form reuse schemes in the design as well as the construction phases of a building, including resource allocations (modular form sets, cranes, workers, etc.), and the construction sequence, is vital for ensuring a successful use of modular formwork systems. Computer process simulation techniques are employed in this research for the study of different form reuse schemes to use gang forming systems in building construction. Five form reuse schemes are identified. The CYCLONE modeling methodology is employed to develop computer models for each of them. MicroCYCLONE simulations and sensitivity analyses of the schemes, using different numbers of form sets, cranes, and labor crews, are then conducted for a real case to assess their impact on the productivity as well as the cost-effectiveness of the operation. The objective is to better understand the characteristics of different form reuse schemes and, in turn, to produce better plans for gang forming construction. Thus, the application of modular formwork systems in building construction can be facilitated. 相似文献
