The decoding process of these codes suffers from a high computational complexity which necessitates a high memory requirements to store the intrinsic and extrinsic Likelihood Ratio (LLR) messages. This paper addresses a simplified and efficient coding technique of the binary words carrying the LLR values by storing the difference of two consecutive LLRs instead of the entire values in the Check Node (CN) processor of NB-LDPC Decoder. A combined approach mixing two techniques: partial truncation and 2-bit coding technique leading to a memory reduction of 38 % is also presented. The Monte Carlo simulation results show that the proposed LLR representation schemes do not introduce a significant performance loss of the code.","PeriodicalId":372346,"journal":{"name":"2013 25th International Conference on Microelectronics (ICM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126130188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposal consists in the use of a simple and generic classification algorithm that enables classify the quality of a given video. The main purpose is to objectively classify video quality according to the ITU-T continuous scale, faithfully with human judgment on video quality. The challenge is to create a video quality monitoring tool (VQMT) classifying the video quality directly from the available video quality metrics, by matching the quality level of a given video to a class of video quality among the 5 considered video quality classes (Excellent, Good, Fair, Poor and Bad). Promising results are obtained using a k-NN classification tool trained on a dataset of a subjective experience along with fundamental measurable metrics, namely packet loss rate, peak signal to noise ratio, spatial indexes and temporal indexes. A statistical analysis is provided comparing this solution's performance with data-sets obtained through subjective human rating.","PeriodicalId":372346,"journal":{"name":"2013 25th International Conference on Microelectronics (ICM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128097856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to reduce the input equivalent noise current, a detailed mathematical analysis of the proposed TIA on noise optimization is given. Using this approach, the TIA achieves a constant gain of 70dBΩ from 50kHz to 2.7kHz when connected to a 0.6pF load at the input. The equivalent input current noise is 2.4pA/√(Hz) up to 1.6GHz. The amplifier remains linear up to 2mA and can withstand photodiode input DC currents up to 1mA. The typical power consumption of the amplifier is 73mW including the output buffer.

This paper presents the design and implementation of a complete PCA IP core for gas application on the Zynq programmable system on chip (SoC). All steps of PCA starting from the mean computation to the projection of data onto the new space, passing by the normalization process, covariance matrix and the eigenvectors computation are developed in C and synthesized using the new Xilinx VIVADO high level synthesis (HLS). The Jacobi method is used to find the eigenvectors and different approaches for the implementation of the PCA core on the heterogeneous Zynq platform are proposed. The hardware implementation of the presented PCA algorithm for a 16 × 30 matrix is faster than the software one with a speed up of 1.41 times when executed on a desktop running a 64-bit Intel i7-3770 processor at 3.40GHz.

Back-gate biasing is exploited to enhanceWrite Margin (WM) and Read Noise Margin (RNM), while built-in feedback mechanism is employed to achieve variation tolerance design during read and standby operations. Proposed cell improve stability by offering stable read and write operations while chip may have different process corners. Three sigma deviations in Static Noise Margin (SNM), RNM and WM due to intrinsic fluctuations alone are projected to demonstrate the stability of cell using 5000 points Monte-Carlo simulations. Compared with the conventional tied-gate 6T cell, the proposed 10T SRAM cells decorate SNM, RNM and WM by 1.9×, 4.7× and 1.6×, respectively. Also, with respect to existing tied-gate 10T SRAM cell, we achieve 6.5% and 20% improvements in RNM and WM, respectively.","PeriodicalId":372346,"journal":{"name":"2013 25th International Conference on Microelectronics (ICM)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114838115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
