These critical assets must be protected against wide array of potential vulnerabilities to uphold the system’s confidentiality, integrity, and availability. Today’s SoC designs contain diverse intellectual property (IP) blocks, often acquired from multiple 3rd-party IP vendors. Secure hardware design using them inevitably relies on the accrued domain knowledge of well-trained security experts. In this letter, we introduce \u0000<monospace>SPELL</monospace>\u0000, a novel end-to-end framework for the automated development of secure SoC designs. It leverages conversational large language models (LLMs) to automatically identify security vulnerabilities in a target SoC and map them to the evolving database of common weakness enumerations (CWEs); \u0000<monospace>SPELL</monospace>\u0000 then filters the relevant CWEs, subsequently converting them to systemverilog assertions (SVAs) for verification; and finally, addresses the vulnerabilities via centralized security policy enforcement. We have implemented the \u0000<monospace>SPELL</monospace>\u0000 framework using popular LLMs, such as ChatGPT and GEMINI, to analyze their efficacy in generating appropriate CWEs from user-defined SoC specifications and implement corresponding security policies for an open-source SoC benchmark. We have also explored the limitations of existing pretrained conversational LLMs in this context.","PeriodicalId":56143,"journal":{"name":"IEEE Embedded Systems Letters","volume":"16 4","pages":"365-368"},"PeriodicalIF":1.7,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142789075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heterogeneous DNN accelerators have emerged as an elegant solution to tackle the workloads’ inherent diversity, achieving significant improvements compared to homogeneous solutions. However, utilizing off-the-shelf architectures provides suboptimal adaptability to given workloads, whereas custom design approaches offer limited heterogeneity, and thus reduced gains. In this letter, we combat these shortcomings and propose an exploration-based framework to holistically design heterogeneous accelerators, tailored for multi-DNN workloads. Our framework is workload-agnostic and leverages architectural heterogeneity to its full potential, by integrating low-precision arithmetic and custom structural parameters. We explore the formed design space, targeting to minimize the system’s energy-delay product (EDP) via heuristic techniques.

However, the low-resolution fabrication of PEs, which results in large feature sizes, poses a challenge for integrating complex designs like those of machine learning (ML) classification systems. Current literature optimizes only the multilayer perceptron (MLP) circuit within the classification system, while the cost of analog-to-digital converters (ADCs) is overlooked. Printed applications frequently require on-sensor processing, yet while the digital classifier has been extensively optimized, the analog-to-digital interfacing, specifically the ADCs, dominates the total area and energy consumption. In this letter, we target digital printed MLP classifiers and we propose the design of customized ADCs per MLP’s input which involves minimizing the distinct represented numbers for each input, simplifying thus the ADC’s circuitry. Incorporating this ADC optimization in the MLP training, enables eliminating ADC levels and the respective comparators, while still maintaining high classification accuracy. Our approach achieves \u0000<inline-formula> <tex-math>$11.2times $ </tex-math></inline-formula>\u0000 lower ADC area for less than 5% accuracy drop across varying MLPs.","PeriodicalId":56143,"journal":{"name":"IEEE Embedded Systems Letters","volume":"16 4","pages":"353-356"},"PeriodicalIF":1.7,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142789080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
