In order to provide less area and low power operation, we adopt MIPS instruction set architecture (ISA) to our processor. The processor consists of five pipeline stages to reduce the critical path. In order to solve the data hazard in pipeline stages, we design the data forwarding unit and stall unit with optimized bubble insertion. The processor is implemented on a field programmable gate array (FPGA), and we verify the functionality of the processor and measure the performance by using the Dhrystone benchmark. The Dhrystone MIPS (DMIPS) is measured at 27.71 at 50 MHz operation.","PeriodicalId":270577,"journal":{"name":"2020 International SoC Design Conference (ISOCC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114631817","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}

Out of all transistor sizings, the lowest write latency is 2.95ns with a corresponding cache area of 2.2756mm2.

Although, previous researchers claimed inside monitoring of vehicle. However, mostly they have performed diver status monitoring. It is quite insufficient for FAV, and proper in-cabin monitoring is an essential demand to ensure safety and security to both, human and vehicle. In this paper, we have proposed a single artificial intelligence (AI) based camera to monitor and understand in-cabin occupants and their behaviors. Further, requirements of monitoring inside the vehicle cabin has been showcased and various irregular situations have demonstrated which should be considered to provide safe and secure ride to the occupants. Furthermore, we have developed our own database due to very few availabilities of such used cases and dataset. It is to facilitate more research in this domain.","PeriodicalId":270577,"journal":{"name":"2020 International SoC Design Conference (ISOCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125406336","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}

TSV is a vertical component which cannot be found in the conventional 2D memory. It plays an important role in improving integration in 3D memory structure. However, due to its temporal variation and technological weakness, error cases occur frequently in TSV. Following this, to increase the reliability of the memory operation, fault detection and correction method for TSV is a new challenge in 3D memory. For the efficient fault correction, fault detection method that classifies hard fault and soft error has been studied. In this paper, a new TSV fault detection method using error pattern analysis will be presented. As a result, the proposed scheme shows higher detection success rate with low area overhead, compared to the conventional scheme.","PeriodicalId":270577,"journal":{"name":"2020 International SoC Design Conference (ISOCC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127781100","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}
