Therefore, power-aware fault-tolerance techniques should be used to manage power and temperature issues. We tolerate both permanent and transient faults through hybrid fault-tolerance techniques. In this letter, at first, we investigate how much power and temperature are increased when a hybrid fault-tolerance technique is applied to multicore embedded systems. Then, we propose a peak-power-aware hybrid fault-tolerant technique to meet the temperature constraint. Transient-temperature-based safe power (T-TSP) is a new power budgeting technique whose calculation is based on the current temperature of the processing core. Assigning dynamic budgets through T-TSP to processing cores allows us to effectively reach the full performance of processing cores. Experiments show that our proposed method reduces peak power and energy consumption on average by 13.5% (up to 50.7%) and 41.8% (up to 67.4%), respectively and improves the schedulability on average by 6.8% (up to 22.4%) compared to state-of-the-art methods while meeting the system reliability target.","PeriodicalId":56143,"journal":{"name":"IEEE Embedded Systems Letters","volume":"16 4","pages":"477-480"},"PeriodicalIF":1.7,"publicationDate":"2024-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140829504","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}

The FA experiences three errors, while the subtractor shows two errors. In both circuits, to improve the speed, output swing, and drivability, the gate diffusion input (GDI) and dynamic threshold (DT) techniques are implemented by carbon nanotube field effect transistor (CNTFET) technology. The FA and subtractor in order are embedded in an 8-bit ripple carry adder (RCA) and an 8-bit subtractor, then they make a new approximate multiplier-free discrete cosine transform (DCT). The 8-point approximate DCT manipulation requires only addition and no multiplication. So, computational complexity is brought down. The DCT shows power delay product (PDP), peak signal-to-noise ratio (PSNR), and a figure of merit (FoM) of 63.61 fJ, 34.96 dB, and 2.39, respectively.

One of the key components in MPSoC is the network-on-chip (NoC), which facilitates the interconnection of various processing elements (PEs), enabling efficient data communication. Several timing attacks, such as Earthquake attack, P+P Firecracker, and P+P Arrow, have been proposed on NoC that exploit the variations in execution times of operations to infer cryptographic keys. In this letter, we propose to leverage the timing attack on NoC to reverse engineer the mapping of each PE onto the MPSoC architecture. To the best of our knowledge, it is the first work that relies on creating the contention between the requests that are sent to different PEs and reveal the layout by just analyzing the reply latency. In the experimental setup, we are able to map PEs for MPSoC consists of Mesh, Torus, Point-to-Point, Ring, and Flattened Butterfly NoC topology with 100% accuracy that can be extremely useful for the attackers in the reconnaissance phase. Further, as the existing mitigation techniques to counter timing attacks are based on the assumption that the contention is created between the packets of secure-insecure domains, they will not be able to mitigate the proposed reverse engineering attack.","PeriodicalId":56143,"journal":{"name":"IEEE Embedded Systems Letters","volume":"16 4","pages":"449-452"},"PeriodicalIF":1.7,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797914","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}

Nevertheless, the task of achieving these objectives presents a complex and demanding challenge. Ensuring secure transmissions while simultaneously minimizing error rates requires the implementation of multistage information processing techniques that integrate coding and encryption methods, which may unfortunately lead to an undesired increase in transmission delay and latency. This letter presents an innovative crypto-coding framework capable of concurrently achieving essential encryption and coding within a single, streamlined process. By leveraging this approach, we aim to address the tradeoff between security, efficiency, and transmission delay, thus contributing to the advancement of secure and efficient communication standards. In this letter, we present a comprehensive evaluation of the proposed scheme, assessing its impact on final system error probability, encryption efficacy, and the complexity of hardware implementation. Our findings shed light on the potential benefits of this approach for future communication standards.","PeriodicalId":56143,"journal":{"name":"IEEE Embedded Systems Letters","volume":"16 3","pages":"287-290"},"PeriodicalIF":1.7,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140006552","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}

This letter proposes the field-programmable gate array (FPGA)-based hardware implementation of a novel lightweight deep convolutional neural network (DCNN) model to detect PN and TB ailments using CXR images. Initially, the proposed DCNN (consisting of ten layers) is trained using the Google Cloud central processing unit (CPU) to obtain the model weight and bias parameters. Then, the register transfer logic (RTL) for the trained DCNN model is generated by the VIVADO high-level synthesis (HLS) framework using HLS for machine learning (HLS4ML) with fixed-point representation (8 bit for integer and 12 bit for the fractional part). The hardware implementation of the suggested DCNN model is performed using the PYNQ-Z2 FPGA framework to detect TB and PN diseases automatically. The experimental results demonstrate that the proposed DCNN model has obtained accuracy values of 96.39% and 95.63% on the Google-Cloud CPU and PYNQ-Z2 FPGA frameworks using 422 CXR images in the inference phases. The inference time of the proposed DCNN model on the PYNQ-Z2 FPGA framework is reduced by 85.19% compared to the CPU-based implementation. The suggested DCNN model has only 1831 parameters, less than the transfer learning (TFL) and existing CNN-based models to detect TB and PN using CXR images.","PeriodicalId":56143,"journal":{"name":"IEEE Embedded Systems Letters","volume":"16 4","pages":"445-448"},"PeriodicalIF":1.7,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140003875","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}
