We propose a multiple-voting-based joint detection-decoding algorithm for nonbinary low-density parity-check (LDPC)-coded modulation systems. This algorithm is inspired from the reliability-based JDD algorithm for nonbinary LDPC-coded modulation systems, that has been proposed recently, in which the accumulated reliability of symbols based on one-step majority-logic decoding algorithm and the Chase-like...
Flash Translation Layer (FTL) is a key technology in a Solid–State Disk (SSD) system to manage the data transfer. Different mapping granularity in FTL will cause a change in the read/write performance and the size of mapping table. For the scenario that big capacity storage needs to hold high performance, on the basis of former mapping algorithms, this paper design a mapping method based on grouping...
In this paper, we propose a new modeling and identification approach for piezoelectric-actuated stages cascading hysteresis nonlinearity with linear dynamics, which is described as a Hammerstein-like structure. In the proposed approach, the hysteresis and linear dynamics together with the delay time and higher order dynamic behaviors are obtained with three data-driven identification steps under designed...
Onboard Failure Logging (OBFL) is an advanced feature of hardware system. It records failure-related data which is useful for failure analysis process and system reliability improvement. OBFL records are event sequences with multi-attributes. There are lots of algorithms proposed for sequential pattern mining, whereas not much effort has been made to use attribute held by events. However such attributes...
In this paper, we introduce a coarse-grained dynamically reconfigurable fabric, named Reconfigurable Processing Unit (RPU), which is implemented on a 5.4×3.1 mm2 silicon with TSMC 65 nm LP1P8M technology. This fabric consists of 16×16 multi-functional Processing Elements (PEs) interconnected by an area-efficient Line-Switched Mesh Connect (LSMC) routing. A Hierarchical Configuration Context (HCC)...
In this paper, we propose a novel method to determine whether a scanned text document is right side up or upside down. The text documents discussed here are limited to English, Chinese and Japanese where we find that the punctuation marks located on the bottom of the text line have a much more frequent occurrence than those on the top. Thus, by calculating the number of punctuation marks on the bottom...
Computing-intensive algorithms which occupy most of executing time are always the main bottleneck in real-time or high quality video applications. In this paper, the optimization methods of the computing-intensive decoding algorithms of H.264, including MC (Motion Compensation), Deblocking and IDCT-IQ (Inverse Discrete Cosine Transform-Inverse Quantization), are proposed firstly, and then implemented...
When users visit Web, it has variety of evaluated factors, take these situations into account, structuring multiple fuzzy matrix, using several associated SOFM neural network being connected to carry out the study on the every evaluated factors, more accurate and scientific in Web mining user access patterns. Finally, using this algorithm in simulation experiment, to some extent, improved user access...
Extended Proportional Integral Derivative (EPID) is a model based control algorithm which consists of a conventional digital PID controller plus an additional compensator. This novel extension to the PID control algorithm offers the same properties as the IMC controller for a broad class of common industrial process models. EPID control simplifies the industrial implementation of IMC and has three...
