摘要：Cryptocurrencies represented by Bitcoin have fully demonstrated their advantages and great potential in payment and monetary systems during the last *** mining pool,which is considered the source of Bitcoin,is the cornerstone of market *** surveillance of the mining pool can help regulators effectively assess the overall health of Bitcoin and ***,the anonymity of mining-pool miners and the difficulty of analyzing large numbers of transactions limit in-depth *** is also a challenge to achieve intuitive and comprehensive monitoring of multi-source heterogeneous *** this study,we present SuPoolVisor,an interactive visual analytics system that supports surveillance of the mining pool and de-anonymization by visual *** is divided into pool level and address *** the pool level,we use a sorted stream graph to illustrate the evolution of computing power of pools over time,and glyphs are designed in two other views to demonstrate the influence scope of the mining pool and the migration of pool *** the address level,we use a force-directed graph and a massive sequence view to present the dynamic address network in the mining ***,these two views,together with the Radviz view,support an iterative visual reasoning process for de-anonymization of pool members and provide interactions for cross-view analysis and identity *** and usability of SuPoolVisor are demonstrated using three cases,in which we cooperate closely with experts in this field.

摘要：介绍了第三代输入输出总线PCI Express的事务层组成结构与功能,自顶向下对事务层进行了系统级设计,运用硬件描述语言Verilog HDL对其实现。使用Synopsys VCS进行功能仿真,得出了仿真波形,验证了该设计的正确性,符合PCI Express事务层协议。

摘要：escalate上升transaction交易disclose揭露buyout全部收买bolster支撑mutiny反叛旧金山消息:微软公司再次谋求与雅虎合作,挑战网络搜索和广告巨头谷歌,尽管此次重新开始的对话尚未涉及到先前接管雅虎的意向。

摘要：应用的需求和集成电路工艺的发展促进了复杂的片上系统(SoC)的实现,同时也要求新的设计方法以支持复杂SoC的设计。高效率的软硬件联合设计需要对整个SoC进行更高层次(例如transactionLevel)的抽象以提供更快的仿真速度及更高效率的SoC设计验证方法。本文介绍了一种重要的SoC设计语言:SystemC,以及基于SystemC的transactionLevel模型和使用transactionLevel模型进行SoC的软硬件联合设计的方法。

摘要：近年来,SIP协议得到了广泛应用,本文对SIP协议进行了研究,并在oSIP源码基础上设计和开发了一SIP协议栈,该协议栈提供快速产生SIP消息的API、对SIP消息进行解析和处理的简单API以及生成和解析一些SIP扩展信令(如INFO、re-INVITE)的简单API。
