These modular entities represent objects in object-oriented design methods, and they function as building blocks of embedded systems. This concept enables you to build new embedded systems from electronic Lego-like building blocks. The goal of the EOC is to make designing of embedded systems faster and easier while preserving the commercial applicability of the resulting device. The EOC enables people without comprehensive knowledge in electronics design to create new embedded systems. For experts it shortens the design time of new embedded systems. This article presents the concept and two realized embedded systems: a telerobot and Painmeter.","PeriodicalId":50392,"journal":{"name":"IEEE Design & Test of Computers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/MDT.2009.103","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62465084","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}

Traditionally, the FPGA verification task is performed by running a General Purpose Operating System (GPOS) like Linux, which is debugging inefficient and hard to be controlled. In this paper, the authors have proposed a Verification Purpose Operating System (VPOS) on FPGA to initialize machine resources and to build software contexts for directed or random tests. This framework greatly reduces the debugging complexity by seamlessly interacting with SW-simulation, and considerably increases coverage as opposed to the Linux-based method by providing high flexibility. We assess the feasibility of our approach by applying it to a microprocessor designed by our institute.","PeriodicalId":50392,"journal":{"name":"IEEE Design & Test of Computers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/MDT.2009.104","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62465131","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}

Most existing error detection techniques suffer from high power and performance costs, and / or additional design complexity. Circuit failure prediction, together with CASP on-line diagnostics, enable design of robust systems that can effectively overcome reliability challenges associated with early-life failures and aging. The key attractive feature of such an approach is its significantly reduced power cost compared to traditional error detection. It also opens up new research opportunities across multiple abstraction layers (circuit, architecture, virtualization/OS, and applications) for designing optimized robust systems with respect to reliability requirements while balancing power, performance, area, and design complexity constraints. Such global optimization is essential for robust systems of the future.","PeriodicalId":50392,"journal":{"name":"IEEE Design & Test of Computers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/MDT.2009.132","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62465665","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}

Targeting multi-core processors, we further present design techniques that can effectively reduce the access latency of 3D DRAM L2 cache, hence improve the overall 3D integrated computing system performance. The effectiveness of these developed design techniques have been successfully evaluated based on CACTI-based memory modeling and full system simulations over a wide spectrum of multi-programmed workloads.

In previous simulation fault injections, the original simulation model is modified to implement a saboteur module or many mutants. This creates a problem since the architectural complexity of current SoCs is expected to increase rapidly in the 32 nm era. Furthermore, the modification process may incur additional tasks, such as verification and validation of the modified simulation model. Our simulation fault injection environment uses the modified SystemC simulation kernel augmented for fault injection experiments. The proposed methodology offers the following advantages over previous simulation fault injection methods. First, it does not require changes in the target simulation design model. Second, it minimizes the simulation hardware resource requirements and simulation time. Third, it allows mixed simulation of the ESL model and the register transfer level model using wrappers. To demonstrate the effectiveness of the proposed methodology, we designed the SystemC models of MIPS and TMR MIPS processors and ran the benchmark SW from MiBench to compare the failure rates of the two processors.","PeriodicalId":50392,"journal":{"name":"IEEE Design & Test of Computers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/MDT.2009.128","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62465550","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 severity of Negative BTI (NBTI) degradation in two major circuit applications: random logic and memory array. Simulation results obtained from 65nm PTM node shows that NBTI induced degradation in random logic is considerably lower than that of a single transistor. Simple delay guard-banding can efficiently mitigate the impact of NBTI in random logic. On the other hand, NBTI degradation in memories results in severe READ stability degradation, especially when combined with random process variation. Moreover, in scaled technology nodes, finite number of Si-H bonds in the channel can induce a statistical random variation in the degradation process. Simulations using 32nm/22nm Predictive Technology Model (PTM) shows that statistical random variation of NBTI, on top of random dopant fluctuation (RDF) results in significant random Vt variation in PMOS transistors, resulting in considerable degradation in static noise margin (SNM) of memory cells.","PeriodicalId":50392,"journal":{"name":"IEEE Design & Test of Computers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/MDT.2009.133","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62465679","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}
