Reducing this excessive guardband is highly desirable, but causes timing errors in synchronous circuits. We propose a methodology for supervised learning based models to predict timing errors at bit-level. We show that a logistic regression based model can effectively predict timing errors, for a given amount of guardband reduction. The proposed methodology enables a model-based rule method to reduce guardband subject to a required bit-level reliability specification. For predicting timing errors at bit-level, the proposed model generation automatically uses a binary classifier per output bit that captures the circuit path sensitization. We train and test our model on gate-level simulations with timing error information extracted from an ASIC flow that considers physical details of placed-and-routed single-precision pipelined floating-point units (FPUs) in 45nm TSMC technology. We further assess the robustness of our modeling methodology by considering various operating voltage and temperature corners. Our model predicts timing errors with an average accuracy of 95% for unseen input workload. This accuracy can be used to achieve a 0%-15% guardband reduction for FPUs, while satisfying the reliability specification for four error-tolerant applications.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133573550","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}

These proposed systems use a spiral inductor built using TSV technology. The Resonant Inductive Coupling system increases the amount of magnetic flux linked between coils and improves the power transmission significantly. A proposed architecture based on TSV technology for a variable bridge spiral inductor is demonstrated and characterized. Where, we can obtain different values for the inductor according to the switch state, whether it is ON or OFF. In addition, TSV is used to construct transformer-coupled power amplifier. A new architecture for on-chip bandpass filters, based on through silicon via (TSV) technology. This architecture is the first in literature. According to the simulation results, the TSV-based bandpass filter has an insertion loss of 1.5 dB at 90 GHz and 20 GHz passband from 80 to 100 GHz. This band can be tuned by changing the dimensions of the coupled TSVs. TSV are also used to build an antenna on high resistivity substrate. The characteristic of this antenna is a function of TSV diameter, TSV length, and silicon resistivity. Compared to conventional on-chip antennas who suffers from low gain and low radiation efficiency, our novel antenna provides better performance parameters such as higher radiation pattern efficiency and higher gain as the antenna delivers a high gain of 5.8 dBi and the radiation efficiency is 86% over the prescribed range of frequencies. The proposed antenna is centered at 90 GHz with 20 GHz bandwidth. The overall area of the proposed antenna is 400μm×100μm. Building the antenna using TSV technology not only improves the performance, but also improves the isolation between the antenna and other active circuits.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"173 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122976841","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 computational- as well as communication and storage requirements for real-time multi-camera video are huge. High quality stereo- and view interpolation applications require the accurate combination of detailed image features in two or more cameras. The use of lossy video compression algorithms often lowers the accuracy of small details and textures that are probably not noticeable by a human viewer, but that are crucial in disparity calculations, matching, video stitching and 3D model synthesis. This paper makes a quantitative comparison of two lossless video compression methods. The intention is to use them for efficient implementation in System-on-Chip (SoC) architectures in computational camera systems. The methods compared are based on predictive-corrective compression and Huffman encoding as well as derived methods. For efficient hardware implementation alternative methods for the use of the Huffman coding are investigated. The comparison includes the use of Huffman encoding parameters from previous frames in the compression of current frames.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123014794","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}
