To mitigate the effects of errors and enable error recovery, processors need to incorporate fault tolerance techniques. One common type of error is SEU (Single Event Upset), which affects various microelectronic devices including microprocessors, microcontrollers, and semiconductor memory devices. While error mitigation techniques have been developed for processors based on architectures like ARM (Advanced RISC Machine) and MIPS (Million Instructions Per Second), there is a gap in research for open-source ISAs (Instruction Set Architecture) like RISC-V, which this paper aims to address. This paper focuses on designing a fault-tolerant microarchitecture for a RISC-V processor that can correct one-bit errors, detect up to two-bit errors, and integrate lockstep and pipeline rollback features at a lower LUTs (Look Up Tables) consumption by re-using the same hardware pipeline for error mitigation and recovery through instruction mimicking. By incorporating these features, the proposed approach enhances the system’s fault tolerance by detecting and correcting errors caused by transient events and achieves a lower effective die size upon realization compared to contemporary works. The proposed microarchitecture design was simulated and synthesized using the Vivado Design Suite 2023.1 and implemented on a Zynq 7000 SoC ZC702 Evaluation Kit.</p></div>","PeriodicalId":54973,"journal":{"name":"Integration-The Vlsi Journal","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142242434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This task is considered crucial in the synthesis of high-quality cryptographic primitives, particularly S-boxes. In accordance with this requirement, the current article demonstrates a strategy for generating an 8 × 8 S-box drawing over an LA-ring of order 1024, which is considered a substantial class of non-associative rings. For the purpose of investigating LA-ring and their practical uses, it is essential to have illustrative examples. However, obtaining such examples using current methods is tedious and yields limited results. Therefore, this research explores an intriguing opportunity for an extensive exploration of LA-ring, far exceeding the limitations previously established and offering a valuable analytical approach for creating examples of higher-order LA-ring by drawing upon lower orders. The manuscript also performs a variety of standard evaluation tests based on five core indicators, which highlight their potential as parallels to the existing frameworks. By using the crafted S-box, an image encryption approach is launched that aims to enhance security measures. It is therefore seen that the recommended S-box has shown a high potential for causing confusion during the substitution phase, and a 3D chaotic map is implemented for the pixel permutation in order to create diffusion into the colour image. Certainly, the discovery is leading to a foundational framework among academics and is expected to serve as the basis for numerous implementations in the future.</p></div>","PeriodicalId":54973,"journal":{"name":"Integration-The Vlsi Journal","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142242433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the last decade, significant attempts to advance millimeter-wave and terahertz electronics and platforms have been made. Notably, there have been ground-breaking advancements in active components, including modulation techniques, low-noise receivers, efficient and high-output-power signal generators, and high-frequency clock synthesizers. Nevertheless, since energy efficiency is of paramount importance for interconnect applications, it is necessary to prioritize efficiency enhancements over improvements in signal power, signal integrity and noise related performance. Strategies to improve system output power and phase noise as well as strategies to reduce channel loss and channel electromagnetic crosstalk should leverage alternative approaches, such as architectural optimizations and array configurations, rather than prioritizing energy efficiency. As such, the progression of passive channel technology is equally vital. While reducing channel insertion loss is essential for extending communication reach, channel dispersion and crosstalk limitations at the interface level present critical challenges to achieving optimal bandwidth over distances of up to a few meters. This underscores the need for a balanced focus on both active and passive component innovations to fully harness the potential of millimeter-wave and terahertz interconnects in overcoming the limitations of current CMOS technologies.</p></div>","PeriodicalId":54973,"journal":{"name":"Integration-The Vlsi Journal","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142228524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most placement algorithms estimate the design performance with a half-perimeter wirelength (HPWL) and target it as their optimization objective. The wirelength model used by these algorithms limits their ability to optimize the internal routing topology, which can lead to discrepancies between estimates and the actual routing wirelength. This paper proposes an analytical placement algorithm to optimize the internal routing topology. We first introduce a differential wirelength model in the global placement stage based on an ideal routing topology RSMT. Through screening and tracing various segments, this model can generate meaningful gradients for interior points during gradient computation. Then, after global placement, we propose a cell refinement algorithm and further optimize the routing wirelength with swift density control. Experiments on ICCAD2015 benchmarks show that our algorithm can achieve a 3% improvement in routing wirelength, 0.8% in HPWL, and 23.8% in TNS compared with the state-of-the-art analytical placer. On industrial benchmarks, our algorithm can also achieve a 10.6% improvement in routing wirelength, 27.3% in WNS, and 34.4% in TNS.</p></div>","PeriodicalId":54973,"journal":{"name":"Integration-The Vlsi Journal","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142150576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
