Flash ADC is widely used in high-speed systems. However, practical flash ADC design is very challenging where experience plays a significant role. ADC design involves in many factors at different levels including architecture, circuit, device and technology. This paper reports a quantitative design methodology for capacitive interpolated flash ADCs, which establishes a design matrix that links ADC chip performance with architecture, block circuit, devices and process parameters. Complex relationship among critical ADC specs, such as, sampling speed, interpolation factors, number of stages, preamplifier bandwidth and transistor parasitic effects, etc, are described. An accurate dynamic power analysis technique is depicted. This flash ADC design method was validated using several designs in 90nm and 130nm CMOS technologies.","PeriodicalId":380183,"journal":{"name":"2010 International SoC Design Conference","volume":"649 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132022527","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}

VLIW (Very Long Instruction Word) processors have been used as a coprocessor to accelerate the performance of various CODECs in the embedded systems, e.g. TI Davinci, but the general VLIW has too much redundancies if the applications required to be executed on the VLIW are restricted. In this paper, we propose a VLIW processor focused on the DCT and Quantization of H.264. Our proposed architecture has 4 issue slots and 16 bit width data path which is half of the TI's TMS320C6× series, but performs better than the TMS320C6× series in terms of cycle count and throughput.","PeriodicalId":380183,"journal":{"name":"2010 International SoC Design Conference","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125215046","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}

As process moves to finer technologies, leakage power significantly increases very rapidly due to the high transistor density, reduced voltage and oxide thickness. We first experimentally investigate existing low-power techniques and point out problems with them. We then propose a family of circuit types for low-power design centered around inserting controlling transistors between pull-up and pull down circuits as well as between pull-up circuits/pull down circuits and power/ground. We investigate the characteristics of proposed gate types in terms of ability to reduce power consumption and their associated delay overhead. In addition, several variations of drain gating are discussed. In the end, an overall procedure for low-power circuit design is proposed by intelligently mixing various proposed circuit types for gates in the circuits based upon gate criticality analysis. Extensive SPICE simulation results were reported using 45nm, 32nm and 22nm process technologies. Significant power reduction is achieved with zero or little increase in the critical path delay of the overall circuits.","PeriodicalId":380183,"journal":{"name":"2010 International SoC Design Conference","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116728048","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}

Unfortunately, depth maps captured with the Time-of-flight (TOF) cameras have limited resolution and poor image quality, being severely influenced by the random and systematic noise, which makes them inapposite for generating high quality 3D images. In this paper, we have further analyzed a framework for upsampling the resolution of depth maps that jointly uses Gaussians of spatial and depth differences of low resolution depth map's pixels along with Gaussian of color intensity difference from high resolution 2D color image of the same scene. The variance of the Gaussian functions controls the amount of smoothing in uni-planner area and sharpness at boundaries. Using bigger variance smooths uni-planner area but blurs edges and vice versa. We have devised a method to adaptively calculate and use variance to get smoother surface and sharper edges of upsampled depth map with minimized noise.","PeriodicalId":380183,"journal":{"name":"2010 International SoC Design Conference","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116751514","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}

One of the ways to understand the circuit behavior under the process variations is to analyze the rare events that may happen due to such process variations. The Statistical Blockade (SB) is a approach for such rare events analysis. In SB, the classification threshold selection becomes very important for different tail regions which is related to the number of rare events simulation. This paper presents the values of classification threshold for different tail regions of typical circuits. It is shown that a given classifier requires different number of training samples depending on classification thresholds.","PeriodicalId":380183,"journal":{"name":"2010 International SoC Design Conference","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128803193","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}
