By employing optimistic concurrency control to execute transactions speculatively, HTM systems promise to deliver the performance benefits typically associated with fine-grained locks. In doing so, HTM systems must deal with transaction aborts. While under certain conditions aborts may be caused by the inherent limitations of hardware structures employed to implement TM (e.g., caches), conflicting concurrent accesses to shared memory locations are generally the prevailing cause for squashing the work done by a transaction</p><p>In this study, we present what we believe to be, to the best of our knowledge, the first characterization of how the aggressiveness of processor cores, particularly their ability to exploit instruction-level parallelism (ILP), interacts with the support for optimistic thread-level speculation offered by HTM systems. We have observed that by adjusting the size of structures that facilitate out-of-order and speculative execution, the number of aborts in the execution of transactional workloads can be altered in best-effort HTM implementations. Our findings indicate that in scenarios with high contention, a smaller number of powerful cores is more suitable, whereas in low contention scenarios, using a larger number of less aggressive cores is preferable. In addition, HTM systems that employ lazy detection and those employing eager detection with requester-stalls resolution, benefit from using simpler cores. In conclusion, abort ratios can be reduced with a careful choice of both processor aggressiveness and design aspects for each application depending on its contention.</p></div>","PeriodicalId":49815,"journal":{"name":"Microprocessors and Microsystems","volume":"104 ","pages":"Article 104975"},"PeriodicalIF":2.6,"publicationDate":"2023-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S014193312300220X/pdfft?md5=ce105b99f7f43d90376360a92db4669c&pid=1-s2.0-S014193312300220X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138404142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, determining an optimal Trojan-resistant hardware design architecture that considers multi-objective orthogonal parameters such as area and delay is crucial. This paper presents a novel exploration of optimal hardware IP core design methodology with Trojan defense capability (<em>i.e.,</em> detection and isolation) during high level synthesis (HLS) that provides isolation of functional Trojan in a system design to ensure reliable and correct functional behavior. The proposed methodology is robust and provides the capability to yield the correct output value using HLS-based triple modular redundancy (TMR) logic and a distinct multivendor allocation policy. Therefore, the proposed HLS methodology can generate an optimal hardware IP core/system-on-chip (SoC) design with functional Trojan defense capability. The paper presents an overall flow of the proposed methodology along with a demonstrative case study on designing optimal Trojan resistant finite impulse response filter (FIR) hardware SoC design. Results of the proposed approach are evaluated in terms of design cost, convergence time, security and optimality analysis, and comparison with prior works. The proposed approach is able to generate fully functional Trojan-resistant optimal SoC designs with minimum overhead, as evident from optimality analysis and design cost.</p></div>","PeriodicalId":49815,"journal":{"name":"Microprocessors and Microsystems","volume":"103 ","pages":"Article 104973"},"PeriodicalIF":2.6,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134656190","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}

For secure EHRs of Mobile Cloud-based eHealth systems, ensuring high security and data privacy, Interplanetary File System in healthcare has traditionally been concentrated. However, there has been a recent push towards achieving high quality of e-health services because blockchain-based health care applications require QoS guarantees in terms of requirements such as network latency and end-to-end delay. In this work, an Extended Validation Certification-based Fischer Neural Network Optimization (EVC-FNNO) method for secured Mobile Cloud-based E-Health Systems is proposed. With the identity being the digital certificate, the EVC is provided with the identity to the mobile cloud user who will transact in the network. In this way, the mobile cloud user is being ensured to access the ledger for the transaction. Therefore, both data privacy and security is said to be provided. Next, with Fischer Neural Network Optimization (FNNO), every authenticated mobile cloud user via EVC then possess a copy of shared ledger, therefore resolving data acquisition in cloud server and hence solving network latency. The proposed method is verified by some demonstrative examples in addressing QoS. The empirical results show that the EVC-FNNO method provides an efficient solution by validating the mobile cloud user sensitive health information with digital certificate. Security analysis proves that the EVC-FNNO method is secure. We also conduct comprehensive performance evaluations that demonstrate the high efficiency of the EVC-FNNO method in terms of end-to-end delay, network latency and data privacy, compared to the existing data sharing methods.</p></div>","PeriodicalId":49815,"journal":{"name":"Microprocessors and Microsystems","volume":"103 ","pages":"Article 104969"},"PeriodicalIF":2.6,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91959633","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}

According to these features, FPGAs are a suitable computing substrate for robots. A few vendors have dominated the FPGA market with their proprietary tools and hardware devices, resulting in fragmented ecosystems with few standards and little interoperation. New and complete open toolchains for FPGAs are emerging from the open-source community. This article presents an open-source library of Verilog modules useful for vision-based robots, including reusable image processing blocks for perception and reactive control blocks. This library has been developed using open tools, but its Verilog modules are fully compatible with any proprietary toolchain. In addition, three applications with a real robot and open FPGAs have been developed for experimental validation using this library. In the last application, the mobile robot successfully follows a colored object using two low-cost cameras (to increase the robot’s field of view) and includes a third camera on top of a servo-driven turret for tracking a second independent object while following the first one in parallel. Resource consumption of all applications has been measured and compared with state-of-the-art proprietary toolchains, revealing that reconfigurable computing with open FPGAs using open tools is now an attractive alternative to designing and creating intelligent vision-based robotic applications using vendor-dependent proprietary tools and FPGAs.</p></div>","PeriodicalId":49815,"journal":{"name":"Microprocessors and Microsystems","volume":"103 ","pages":"Article 104974"},"PeriodicalIF":2.6,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0141933123002193/pdfft?md5=944968e7587656838631a9dd978cf062&pid=1-s2.0-S0141933123002193-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134656018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
