• Binary translation is used to allow applications of one instruction set architecture (ISA) to run on another, thereby maintaining the binary level compatibility across ISAs. Conventional software binary translation systems suffer performance loss because of architectural heterogeneity amongst ISAs, control flow translation and context switches. In this paper...
  • As we enter the era of many-core, providing the shared memory abstraction through cache coherence has become progressively difficult. The de-facto standard directory-based cache coherence has been extensively studied; but it does not scale well with increasing core count. Timestamp-based hardware coherence protocols introduced recently offer an attractive al...
  • There is a growing trend towards heterogeneous systems, which contain CPUs and GPGPUs in a single chip. Managing those various on-chip resources shared between CPUs and GPGPUs, however, is a big issue and the last-level cache (LLC) is one of the most critical resources due to its impact on system performance. Some well-known cache replacement policies like L...
  • With the advantages of low latency, high performance and low power consumption, solid state drives (SSDs) have been widely deployed as the cache layer between memory and back-end low-speed storage devices to narrow the performance gap between CPU and storage system. But in virtualization environment, the high integration of virtual machines can introduce a l...
  • To fully explore the merits of non-volatile memory(NVM), we carry out our work from three aspects. Firstly, we focus on the hardware architectures based on NVM. The mainstream architectures are depicted by Figure 1. Secondly, because NVM is very different form HDD and the traditional system software layer is designed and optimized based on HDD....
  • 为培养复合、创新型人才,浙江大学率先提出“系统能力培养”这一概念,开展“构建计算机类专业系统能力培养体系”的教学改革。系统能力是指以计算思维为基本思想来理解计算机系统整体性、关联性、层次性、动态性和开放性,掌握计算机软硬件协同工作及相互作用机制,综合运用多种知识与技术完成全系统开发的能力,主要包括系统分析能力、系统设计能力、系统工程能力、系统创新能力。教学团...
  • 智能医疗相关研究背景介绍智能医疗是指以物联网、RFID等近期产生并得到广泛使用的相关技术为基础、以提升医疗过程中的信息化程度并推动医疗行业的进一步发展为目标的一系列方法的统称。本项目目前的研究范围包括医疗数据的实时采集和医院药品存储的自动化管理。医疗数据实时采集医疗数据的采集相关技术是智能医疗的核心技术之一。医院的不同科室中的各类医疗设备在诊断、治疗的过程中均会...
  • 车载碗形全景环视系统背景介绍汽车较多的刮擦和碰撞都发生在低速、复杂的路况场景下。由于驾驶员坐在车内,在车前、车两侧,车后均存在较多的盲区,再加上不同车型的长度、宽度差异较大,即便是有经验的驾驶员也不能保证能安全通过,更不用说一些新手和车感不太好的驾驶员。如果在盲区还有老人或者儿童,后果会更加严重。现在主流的泊车辅助产品有全方位声呐雷达系统和单独的后视或侧视工...
