FHE requires arithmetic operations on data with Large Arithmetic Word Size (LAWS) over 64-bit. The Chinese Remainder Theorem (CRT) is used to process such operations in 64-bit architecture. However, since the CRT itself involves the operations on LAWS data, long latency and many hardware resources are required to process the operations. In this paper, we propose a hardware architecture that performs LAWS operation of CRT and inverse CRT (iCRT) through recursive arithmetic operation of Small Arithmetic Word Size (SAWS) data, reducing resource usage and accelerating execution. The proposed hardware was implemented to operate at 100 MHz frequency on the FPGA, and showed latency of 91.2 us and 24.39 us, respectively, for executing CRT and iCRT with only 68 DSP and 65 LUTRAM, and a small number of LUTs and FFs.","PeriodicalId":373752,"journal":{"name":"2023 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121933954","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}

To handle this problem, we propose a novel neural network compression algorithm that can maintain the core features and remove redundant features in the convolutional layer as an aspect of multi-head convolutional neural network architecture.

The enhancement patterns on CEUS are composed of arterial, portal venous, and late phases, where the hepatic arterial phase provides information on the degree and pattern of vascularity, and the portal venous and late phases provide important information on the differentiation between benign and malignant liver lesions. The enhancement patterns of HCC on CEUS are hyper-enhanced in the arterial phase. Therefore, we propose learning-based frameworks to differentiate between hepatocellular carcinoma (HCC) and focal nodular hyperplasia (FNH) during the arterial phase. We design artificial neural networks to learn the change of characteristics over time for the differentiation of HCC from FNH. We had gathered CEUS videos during the arterial phase for 4 years in Samsung Medical Center (SMC) and picked out only small hepatic lesions under 3 centimeters. From these datasets, the proposed novel 3D-CNN and CNN-LSTM networks show accuracy rates of 100% and 98% for 10-fold and 5-fold cross-validations. In the end, the proposed models are proved to be feasible for accurate automatic classification between HCC and FNH in livers.","PeriodicalId":373752,"journal":{"name":"2023 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"2017 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132577259","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}
