3G上网 想说爱你不容易

2009年7月7日,北京电信在3G放号近四个月后才公布了3G手机资费标准,同时推出八项3G业务。从7月8日起,用户可以申请3G手机上网日租套餐或3G手机上网月租套餐,并享受与2G套餐相同的语音资费。这实际上是中国电信全国首个完整版本的3G资费标准。而这个3G资费标准让人期待已久——中国联通5月17日试商用时就全部公布了3G手机和上网卡资费,中国电信更早于3月23日就开始3G放号,但当时只是3G上网卡商用,因此,中国电信的3G手机资费到底如何一直是个谜。至此,三大＂不差钱＂的运营商的3G资费标准全部大白于天下。     

3维GIS空间建模方法评述

3维(3D)空间建模方法是3DGIS研究的核心和难点之一,是建立3DGIS的基础。迄今为止,3D空间建模方法多种多样,建模对象不同,建模方法也随之不同。根据3D空间建模研究的对象,以地球表面为界分为地理空间建模和地学空间建模两大类,并通过现有3D空间建模方法的对比研究,提出了现有3D空间建模研究的关键问题。     

势不可挡的3D潮 PSP变身3DS

3DS以充满立体感的裸视3D效果吸引了游戏玩家的眼球,但高昂的价格让我等手持PSP主机的玩家们望而却步。其实,咱不用羡慕3DS的裸视3D,只要你有一副3D红蓝眼镜,然后给PSP装一个小小的3D插件,即可在PSP上享受立体到爆的3D游戏效果了。

The IC* model of parallel computation and programming environment

The IC* project is an effort to create an environment for the design, specification, and development of complex systems such as communication protocols, parallel machines, and distributed systems. The basis of the project is the IC* model of parallel computation, in which a system is specified by a set of invariant expressions which describe its behavior in time. The features of this model include temporal and structural constraints, inherent parallelism, explicit modeling of time, nondeterministic evolution, and dynamic activation. The project also includes the construction of a parallel computer specifically designed to support the model of computation. The authors discuss the IC* model and the current user language, and describe the architecture and hardware of the prototype supercomputer built to execute IC* programs

DAC Highlights

The 43rd Design Automation Conference presents leading-edge industry practices and academic research across IC, embedded-systems, and "beyond the die" design technologies and methodologies. The authors discuss the highlights, from keynote talks by reknowned personalities in the semiconductor industry to hands-on tutorials.     

Automating Postsilicon Debugging and Repair

Due to increasing semiconductor design complexity, more errors are escaping presilicon verification and being discovered only after manufacturing. As an alternative to traditional manual chip repair, the authors propose the FogClear methodology, which automates the postsilicon debugging process and thereby reduces IC development time and costs.     

Microarchitectural dl/dt control

This article takes a high level of the power-grid noise problem as it relates to the microarchitectural definition of an IC. Through a set of simulations, the authors relate the noise problem to the details of the circuit and clocking implementation giving insight into the possible method to reduce such noise.     

Conquering noise in deep-submicron digital ICs

As feature sizes decrease and clock frequencies increase, noise is becoming a greater concern in digital IC design. The authors describe a verification metric, noise stability, which guarantees functionality in the presence of noise, and a CAD technique, static noise analysis, for applying this metric on a chipwide basis     

Ontology-based information content computation

The information content (IC) of a concept provides an estimation of its degree of generality/concreteness, a dimension which enables a better understanding of concept’s semantics. As a result, IC has been successfully applied to the automatic assessment of the semantic similarity between concepts. In the past, IC has been estimated as the probability of appearance of concepts in corpora. However, the applicability and scalability of this method are hampered due to corpora dependency and data sparseness. More recently, some authors proposed IC-based measures using taxonomical features extracted from an ontology for a particular concept, obtaining promising results. In this paper, we analyse these ontology-based approaches for IC computation and propose several improvements aimed to better capture the semantic evidence modelled in the ontology for the particular concept. Our approach has been evaluated and compared with related works (both corpora and ontology-based ones) when applied to the task of semantic similarity estimation. Results obtained for a widely used benchmark show that our method enables similarity estimations which are better correlated with human judgements than related works.     

Preventing IC Piracy Using Reconfigurable Logic Barriers

Editor's note:Hardware metering to prevent IC piracy is a challenging and important problem. The authors propose a combinational locking scheme based on intelligent placement of the barriers throughout the design in which the objective is to maximize the effectiveness of the barriers and to minimize the overhead.—Farinaz Koushanfar, Rice University
