针对Soc系统软硬件划分问题,将量子算法应用于Soc系统的软硬件划分过程,提出一种基于量子免疫原理的软硬件划分算法.该算法引入基于免疫原理的群体多样性保持策略,在量子算法优化过程中尽可能保持群体的多样性,避免早熟现象.并利用量子旋转门进行量子更新,保证抗体群朝着优秀方向进化,有效克服了量子遗传算法容易陷入局部最优的缺点.仿真实验表明,该算法有效地解决了软硬件划分问题,不但具有较强的搜索和跳出局部最优的能力,而且有效提高了解的精度,获得了更合理的软硬件划分结果. 相似文献

In this paper,a discrete-time analysis of the third-order charge-pump based phase-locked loops (CPLLs) is presented in the presence of loop delay.The z-domain analysis of the closed-loop transfer function is derived and compared with the traditional s-domain method.The simulation results under SPECTRE show that,due to the sampling nature of CPLL,the traditional s-domain analysis is unable to predict its jitter peaking accurately,especially when the loop delay is taken into consideration.The impact of loop delay on the stability of the third-order CPLL system is further analyzed based on the proposed way.The stability limit of the wide bandwidth CPLL with loop delay is calculated.The circuit simulation results agree well with mathematical analysis. 相似文献

基于树的包容匹配思想,把积件的查询转化为查询树与积件标注树之间的匹配.通过研究积件查询的特点,提出积件标注树匹配的3个定理.在此基础上,提出积件查询的逆路径字符串匹配算法.该算法从叶节点开始进行匹配查找,同时考虑从叶节点到根节点的路径长度关系,能尽早终止不能匹配成功的路径,避免了字符串的循环反复查找,同时利用同一路径长度下字符串按字典排序,跳过大量不可能匹配的路径.实验结果表明,此方法在保持积件查找速度的前提下,能有效提高积件的查全率和查准率. 相似文献

An integrated laser diode driver(LDD) driving an edge-emitting laser diode was designed and fabricated by 0.35 μm BiCMOS technology. This paper proposes a scheme which combines the automatic power control loop and temperature com-pensation for modulation current in order to maintain constant extinction ratio and average optical power. To implement tem-perature compensation for modulation current,a novel circuit which generates a PTAT current by using the injecting base current of a bipolar transistor in saturation region,and alternates the amplifier feedback loop(closed or not) to control the state of the current path is presented. Simulation results showed that programmed by choice of external resistors,the IC can provide modu-lation current from 5 mA to 85 mA with temperature compensation adjustments and independent bias current from 4 mA to 100 mA. Optical test results showed that clear eye-diagrams can be obtained at 155 Mbps,with the output optical power being nearly constant,and the variation of extinction ratio being lower than 0.7 dB. 相似文献

Comprehensive student profiling is described as an alternative to exclusively teacher-controlled, academic subject focused records of students' progress. Features of profiling that are highlighted include its multidimensionality, participatory nature, and formative and summative functions. The rationale for adopting comprehensive student profiling rather than relying only on discrete, norm-referenced performance evaluations is discussed with reference to the historical innovation and eventual nation-wide adoption of profiling in British schools and the developmental objectives of the pastoral care movement in Singapore schools. 相似文献

The article examines academic leaders’ conceptions of research profiling. Global science policies, including the Finnish governmental policy, promote the identification of areas of research excellence and recommend resource concentration on them. However, as active agents, leaders may have competing, even conflicting views on the pros and cons of the institutional norm of selective research excellence and research steering. Drawing on the ideas of micro-level institutionalism, this study seeks answers to the following questions: What kinds of conceptions of research profiling do the academic leaders have? How are these connected to the goals that the leaders are trying to achieve with profiling? The data comprised 15 interviews with leaders at different organisational levels in two Finnish research universities. Two general conceptions of research profiling were identified: profiling as an instrument of strategic management and profiling as symbolic management. The conceptions were connected to various rationales, such as strengthening research and communicating to the external environment. By emphasising the variability and incoherence of leaders’ conceptions and the underlying rationalities, the study contributes to understanding how academic leaders make sense of the complex issues they face and how they cope with various demands. 相似文献

This paper examines how institutional positioning has emerged in the meaning-making activities between Finnish higher education institutions and the Ministry of Education and Culture. The study is based on a qualitative analysis of the performance agreement documents of all higher education institutions filed with the ministry for contract periods 2010–2012 and 2013–2016. The results show that, in the first cycle, higher education institutions used profiling vocabulary in vastly different ways, and their lists of priority areas were quite wide ranging. By the second cycle, profiling statements had become more specific and structurally more alike, but the lists of priority areas continued to have a wide scope. As a response, the Ministry has consistently demanded and rewarded more focused profiling efforts and used the concepts of profiling to support other steering measures. 相似文献

Swarm intelligence approaches, such as ant colony optimization (ACO), are used in adaptive e-learning systems and provide an effective method for finding optimal learning paths based on self-organization. The aim of this paper is to develop an improved modeling of adaptive tutoring systems using ACO. In this model, the learning object is personalized based on learning and solving problem styles. The purposed algorithm, based on ACO, generates the adaptive optimal learning path. The algorithm describes an architecture which supports the recording, processing and presentation of collective learner behavior designed to create a feedback loop informing learners of successful paths towards the attainment of learning goals. The algorithm parameters are tuned dynamically to conform to the actual pedagogical process. The article includes the results of implementation and experiment represent this algorithm is able to provide its main purpose which is finding optimal learning paths based on learning styles and improved performance of previous adaptive tutoring systems. 相似文献
