Hyperspectral imaging is a rising imaging modality in the field of medical applications, and the combination of both spectral and spatial information provides wealth information for cell classification. In this paper, deep convolutional neural network (CNN) is employed to achieve blood cell discrimination in medical hyperspectral images (MHSI). As a deep learning architecture, CNNs are expected to...
Blockchain is an emerging technology that can be utilized to break ground for secure provenance through the use of a centralized-based application. The method of distributed ledger can serve as the trust machine mechanism to prevent the malicious attacks. This paper introduces a novel service to complement some open-source blockchain protocols. A vital point of adopting blockchain technology is to...
With supercomputer system scaling up, the performance gap between compute and storage system increases dramatically. The traditional speedup only measures the performance of compute system. In this paper, we firstly propose the speedup metric taking into account the I/O constraint. The new metric unifies the computing and I/O performance, and evaluates practical speedup of parallel application under...
We demonstrate a novel vertical channel 3D NAND Flash architecture — SGVC. SGVC device is a single-gate, flat-channel TFT charge-trapping device with ultra-thin body. Our novel array decoding method enables a tight-pitch (25nm HP) metal BL design to fulfill the large page size (16KB for one plane) for high-performance NAND product. The SGVC flat cell possesses excellent P/E window of ∼10V, small X/Y/Z...
Network-on-chip (NoC) has recently emerged as a primary paradigm for interconnecting ever increasing number of on-chip cores in future chip-multiprocessors (CMPs). As the advent of big data era, high volume of traffic injection, combined with the ever-changing patterns will exert severe pressure on some hotspots, leading to serious traffic congestion. These hot nodes will exhaust up the communication...
In part because of the limitations of the TCP/IPprotocols used by the current Internet, the Future Internet has become an attractive network research topic. Recently, several projects focused on the Future Internet have been launched around the globe based on the Open Flow platform, such as those that are part of the GENI project in the U.S., the OFELIA project of FP7 in the E.U., and the FIRST project...
Driven by continuing scaling of Moore's law, computer system becomes more and more complicated. The Network application technology of the computer is a basic course in computer architecture. Computer assisted teaching system is used to make the students understand the Network application technology of the computer more easily. A multimedia teaching system is introduced in this paper. The system consists...
Network on Chip (NoC) is proposed as a promising solution for processors with many cores integrated onto a single chip. The main advantages of NoC are favorable scalability and high bandwidth for on-chip cores and communications. However, OS designed for NoC have not been fully researched to date. Because the microkernel operating system is composed of modules, such architecture is suitable to execute...
Network-on-Chip (NoC) is proposed to solve the communication bottleneck for multi-core SoC. Performance is one of the most critical feature of the NoC. Many different approaches have been introduced to improve the performance of NoC. However, most of them focus on the network part of NoC architecture and neglect other important parts of the system, especially the processor core part. This paper proposes...
Based on services-oriented architecture(SOA), perfSONAR is a web service infrastructure. The set of elementary functions have been isolated and can be provided by different services. A primary goal of perfSONAR is to make it easier to detect performance monitoring problems among different network domains. perfSONAR has been widely accepted as one of the web service standards by NRENs (National Research...
The wide application of embedded systems becomes a trend in the post-PC era. Embedded systems have been deployed in numerous fields which have different requirements of embedded systems architecture. In order to adapt to the needs of different fields, this paper proposes a new course model for embedded system education. This course model extends the previous model which only concerns ARM architecture...
Information security is becoming more and more important in recent years. It covers fruitful contents and still in rapid continuous changes. How to teach information security is a challenge to universities. Distance learning can provide a favorable environment to information security. An information security curriculum of distance learning has been designed in Zhejiang University. Distance learning...
There are two problems emerged while multi-core platform become popular in daily life, no matter for high end or low end. The first is how to fully utilize computing resource of these cores without requirement of large modifications of current software design model. The second is about dividing a piece of serial program into parallel program. However, the latter is the responsibility of compiler,...
Chip MultiProcessor (CMP) has been the main stream in microprocessor design. Shared on-chip L2 caches are widely used in processors with homogeneous CMP architecture. In the paper, we propose a scheduling algorithm for such processors and the shared L2 caches are taken into account in this algorithm. First, the processor cores on chip will be divided into different core groups. The scheduling domain...
As the rapidly development of embedded systems, it is a challenge for universities to fill the gap between education and industry. In this paper, we introduce the experiment designed for embedded system curriculum based on embedded IA first, and then adapt the design to the new promising processor-Atom?? - developed by Intel. At last, we will share our experiences in the experiment teaching of embedded...
With the rapid development of computer science, its education mode also changes a lot. Teaching and learning are not restricted by the physical distance with the help of the networking. Remote education becomes more popular because of its convenience and resource saving. Meanwhile, the network security is a hotspot in the world for the rapid and wide using of the network. In this paper, we share our...
With the development of computer science and technology, computer applications are gradually turning to structure design from code design. In order to improve computer performance and enhance the application level of computer architecture in software engineering, the college of Computer Science and Technology in Zhejiang University has proposed a teaching reform idea, in which Digital Logic, Computer...
