It provides an optimizable flow to deploy on diverse target devices. By exploiting TVM schedule, we can optimize the codegen behavior for our RISC-V architecture. Since RISCV is configurable with the selection on different extension, we can enable multiple extensions depends on the application scene. In our work, we present the flow for enabling and optimizing the RISC-V P extension toward QNN models from TVM. With support from LLVM and a customized deep learning runtime (DLR), we verified our work on both FLOAT32 and prequantized models from Tensorflow Lite. Experiments shows that comparing with FLOAT32 models, our work can achieve 2.7-7.0 times of performance improvement with regard to total instruction count at runtime for pre-quantized version with a set of benchmarks including Mobilenet and Inception-v3. As for accuracy issue, the degradation is tiny for quantization version among 500 images. All experiments are running on RISC-V simulator, Spike with P extension support.","PeriodicalId":235460,"journal":{"name":"2020 International Symposium on VLSI Design, Automation and Test (VLSI-DAT)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129950724","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}

By analyzing the real-time sensing data, the health status of each machinery is usually monitored to reduce the risk of suddenly machine failure. Although massive sensors allocation can leverage the Remaining Useful Life (RUL) estimation for each machinery, the cost for the sensor network construction will become expensive. Hence, it is necessary to have an approach to remove the redundant sensors under a certain constraint of RUL estimation. On the other hand, due to the attractive performance on the object classification, many researches apply Artificial Neural Network (ANN) to decide which allocated sensor should be removed during the training process. However, the current researches aim to remove the redundant sensors based on the sensing data at a specific time, which lacks the intrinsic feature of time-series sensing data. Therefore, the current researches suffer from the problem of sensor under-killing due to the worst-case consideration. In this paper, we consider the information of time-series sensing data to propose an integrated group-based valuable sensor selection algorithm. Because the proposed approach considers the historical data during the redundant sensor removing process, we can reduce the number of involved allocated sensors precisely and significantly. In order to verify the proposed method, we use the Commercial Modular Aero-Propulsion System Simulation (CMAPSS) dataset and adopt Prognostics and Health Management (PHM) score to evaluate the RUL estimation performance. Compared with the conventional approach, the proposed approach can reduce 86% average PHM score and employ fewer sensors to fit the strict constraint of PHM score with less computing overhead.","PeriodicalId":235460,"journal":{"name":"2020 International Symposium on VLSI Design, Automation and Test (VLSI-DAT)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130974802","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 5G (fifth generation) mobile communication standard aims to solve the substantially increased requirement of data rate and the avalanche of traffic volume. One of the promising solutions is to use the millimeter wave frequency band to get the wide available spectrum. To overcome these unfavorable channel properties, i.e. high path loss, propagation loss, rain fading…,e.t.c., the beam-forming, beam tracking together with phased array antenna are the most crucial key technologies.In this paper, we describe the system specifications and the design considerations of the architecture for the RF and beam forming of the 5G mmWave communication system. Then the design challenges and development trends of the 5G mmWave front-end module are presented. Finally, ITRI’s developed 28GHz 5G millimeter-wave development and verification platform is introduced which adopts the hybrid beam-forming architecture designed with a 8/16/32/64-antenna phased antenna array for gNB and/or UE to implement the beam-forming technology, also a beam-tracking algorithm is developed to support the mobile transmission over 100Km/hr.","PeriodicalId":235460,"journal":{"name":"2020 International Symposium on VLSI Design, Automation and Test (VLSI-DAT)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132278576","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}
