The emerging Phase Change Memory (PCM) has many advantages such as good scalability and low leakage. MLC (Multi-Level Cell) PCM further extends the benefits by storing two or more bits per cell and thus reducing the per bit cost. However, adopting MLC PCM in main memory often leads to long write latency, high energy consumption, and degraded performance. In this paper, we propose TriState-SET, a proactive-SET...
The emerging Phase Change Memory (PCM), while having many advantages, suffers from slow write operations. This is mainly due to its asymmetric write characteristic, i.e., for two types of write operations of PCM, SET is much slower than RESET. Recent study has shown that proactively setting dirty memory lines to all ‘1’s can enable RESET-only writes when these lines are written back from the cache,...
HDB3 (High Density Bipolar)is an improved bipolar RZ code, based on the AMI. HDB3 has no DC component, less low-frequency components, the number of attached zeroes is no more than 3. All of the three advantages are beneficial to signal timing recovery. In this paper, by using modern EDA technology, and assistance of FPGA devices and the VHDL, we have designed and realized HDB3 encoder, which has overcame...
40S ribosomal protein S10 is a protein encoded by the RPS10 gene in human, belonging to the S10E family of ribosomal proteins. To explore the structure characteristic of this gene of Ailuropoda melanoleuca, primers were designed based on the known nucleotide sequence of RPS10 gene. The RT-PCR and PCR strategy were employed to isolate cDNA and genome of RPS10 from A. melanoleuca respectively, followed...
Ribosomal protein S18 is a component of the 40S subunit, encoded by the RPS18 gene in eucaryotic cell, belonging to the S13P family of ribosomal proteins. To explore the structure characteristic of RPS18 gene of the Ailuropoda melanoleuca, primers we re designed based on the known nucleotide sequence of RPS18 gene to clone the cDNA and genomic sequences of RPS18 gene of A. melanoleuca by RT-PCR and...
Processor design is a widely studied topic in computer system architecture design. How to improve computer performance is an important part of the computer overall design. In general processors, multiplication components play a decisive role in processor's performance. An important and frequent operation in decimal computations is multiplication. However, due to the inherent inefficiency of decimal...
A joint-coding method based on STBC (space time block code) and pre-coding in coordinated multi-point distributed system is proposed in this paper so as to improve spectrum utilization and edge user's receptivity. Pre-coding rules are adopted correspondingly by each RAU (remote antenna units) to preprocess users' data according to channel state information, and the processed data is transmitted by...
In this paper, we propose a novel multi-class graph boosting algorithm to recognize different visual objects. The proposed method treats subgraph as feature to construct base classifier, and utilizes popular error correcting output code scheme to solve multi-class problem. Both factors, base classifier and error-correcting coding matrix are considered simultaneously. And subgragphs, which are shareable...
Network coding is a promising technology to improve throughput and reliability. However, the benefit of network coding is restricted and affected by network topology, especially in peer-to-peer system. Precise topology awareness can be helpful to improve system performance of network coding in terms of throughput and reliability. In this paper, we propose an innovative scheme TANCF (Topology Awareness...
In this paper, we have designed DOTP (distance of two points) algorithm and some data structure to calculate the shortest distance between the two vertices in Euclidean network. We created a function which had a linear relation with vertices n and edges e in time complexity. This algorithm's time complexity majority related with non-tree edges t which defined in chapter 2 and has a small magnitude...
Ad hoc networks are characterized with frequent link failures and network topology change. These features result in a great challenge to transmit video over ad hoc networks. We propose a novel content-based layered multiple description coding scheme C-LMDC for robust video transmission over ad hoc networks. First determine the region of interest (ROI) of the video image before actual coding. Then...
Off-Chip buses constitute a significant portion of the total system power in embedded systems. Many research works have focused on reducing power consumption in the off-chip buses. While numerous techniques exist for reducing bus power in address buses, only a handful of techniques have been proposed for off-chip data bus power reduction. In this paper, we propose two novel data bus encoding schemes...
Digital broadcasting environment in which digitalized AV contents can be sent has a room for data transmission as well. In this circumstance, effective encoding method of verbose XML type TV-Anytime metadata becomes important and also the broadcasting environment-specific refinement of TV-Anytime transportation specification is in great need. This paper suggests a well-tuned framework for encoding...
In multi-source multi-sink network coding, messages across different sources are coded to increase the overall throughput. The various types of coded information in the network significantly complicate the determination of its capacity region. In this work, we derive explicit inner and outer bounds for acyclic multi-source multi-sink networks based on a cut-based network decomposition technique and...
