In this paper, we improve the support for streaming processing on the Intel HARPv2 platform by proposing strategies such as data ordering, double buffer, and management of multiple memory addresses. We demonstrate the feasibility of this new strategy by a case study with a hardware implementation of the Semi-Global Matching (SGM) algorithm for stereo vision. With these strategies, we can process depth images with a resolution of 1920×1080 pixels achieving a processing rate of about 48 FPS. The processing performance overcomes the state-of-art CPU-FPGA heterogeneous architectures results for processing of the promissing SGM technique.","PeriodicalId":135163,"journal":{"name":"2020 18th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129957623","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}

It is specially designed to be used in edge-combining transmitters and fabricated in a 180nm 1P6M CMOS process. It provides 16 symmetrical phase-shifted outputs for up to 8-times frequency-multiplication using an external edge-combiner. The oscillator is implemented as current-starved RO. It includes a biasing network with threshold regulation for close to 50% duty cycle and equal time delay in all RO stages. The lower corner-frequency is 5 bit adjustable (50MHz to 300 MHz) and the oscillator offers an additional 5 bit trimmable tuning range (20.3MHz to 97.2 MHz). The structure is optimized to operate at 216MHz and shows a phase noise of −96 dBc/Hz at 1MHz offset as well as −76 dBc/Hz in-band phase noise (with locked PLL below 100 kHz offset).

The design is based on using dangling resonators coupled to the output port. One of the unique features of the proposed design approach is that the resonant frequencies of the dangling resonators determine the locations of the transmission zeros. In addition, the design method allows us to relocate the transmission zeros without degrading a reflectionless response at the input port. For verification, we have designed three third-order microstrip line filters centered at 3 GHz having 10 % bandwidth. The filters have been designed to have one transmission zero in the lower stopband and one in the upper stopband. For demonstrating the relocation facility, the filters have been designed to have different sets of transmission zeros. The filters have been fabricated and measured for verifying the presented design method.","PeriodicalId":135163,"journal":{"name":"2020 18th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131870874","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}

Therefore, an evaluation must be carried out in order to diagnose the critical nodes but also to get an idea of the global sensitivity of the circuit, as a proxy to its experimental cross-section. In this work we evaluate two different top-down approaches considering or not the biasing of the impacted transistor to compute the injected charge. Performing an exhaustive evaluation campaign on a high performance buffer as a case of study, it will be shown that the error committed by the charge difference is greater than the one committed by simulating with the simple schematic without layout parasitics. However, the correlation between both approaches is high, so the critical nodes appear in the same order.","PeriodicalId":135163,"journal":{"name":"2020 18th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124232199","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}

Analog-to-feature (A2F) conversion is an acquisition method thought for IoT devices, that perform classification tasks at sub-Nyquist rate, by extracting relevant features in the analog domain and then performing the classification step in the digital domain. Current A2F solutions are designed for a specific application, this paper proposes a method to design a generic A2F converter usable for several signal types. In order to extract information for classification task, we propose to use non uniform wavelet sampling, its drawback is that it brings redundancy and irrelevant information. To reach our goal of decreasing power consumption, we need to extract a small set of relevant features for classification. To achieve this, several features selection algorithms are tested for electrocardiogram (ECG) anomalies detection. We demonstrate that the detection rate of ECG anomalies can reach 98% with less than 10 features extracted.","PeriodicalId":135163,"journal":{"name":"2020 18th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116975093","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 detection complexity grows significantly as the number of antennas increases in the system. Maximum-likelihood (ML) has the optimal performance with the highest complexity, which is prohibitive for implementation. In this work, we propose a serial ML (SML) algorithm, which changes the way of detection from parallel multi-dimensional searching to serial single-dimensional searching to reduce detection complexity. Besides, we employ a valid initial value for the proposed algorithm to obtain a faster convergence. Based on the simulation results, for the system with 128 receive antennas, the proposed SML algorithm outperforms the Minimum Mean Square Error (MMSE) method under different numbers of users and modulation schemes. When achieving a similar performance, the complexity of serial ML is almost a half of that of low complexity Message Passing Detection algorithm in the system with 16QAM and 16 or 32 users. It is demonstrated that our proposed SML method is more suitable for signal detection when the system adopts low order modulation schemes and serves larger number of users.","PeriodicalId":135163,"journal":{"name":"2020 18th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123493008","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}

This paper evaluates the SET sensitivity of state-of-the-art floating gate configurable logic circuit and proposes a novel methodology for filtering a SET pulse generated inside the logic cells by increasing the charge sharing effect on the sensitive node of a cell due to remapping of its configurable switches. Experimental results, performed with radiation particle simulation on several benchmark circuits implemented in a 130nm floating-gate device demonstrate an improvement in filtering SET effects of more than 24% on the average with negligible delay degradation.","PeriodicalId":135163,"journal":{"name":"2020 18th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130585017","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}
