HWNoC-based multicore systems encounter extremely dynamic application workloads that are submitted at run-time. Mapping and scheduling of these applications are critical for system performance, especially for real-time applications. The existing resource allocation approaches either ignore the use of wireless links in task allocation on cores or ignore the timing characteristic of tasks. In this paper, we propose a new deadline-aware and energy-efficient dynamic task mapping and scheduling approach for the HWNoC-based multicore system. By using of core utilization threshold and tasks laxity time, the proposed approach aims to minimize communication energy consumption and satisfy the deadline of the real-time applications tasks. Through cycle-accurate simulation, the performance of the proposed approach has been compared with state-of-the-art approaches in terms of communication energy consumption, deadline violation rate, communication latency, and runtime overhead. The experimental results confirmed that the proposed approach is a very competitive approach among the alternative approaches.","PeriodicalId":13156,"journal":{"name":"IEEE Transactions on Emerging Topics in Computing","volume":"11 4","pages":"1031-1044"},"PeriodicalIF":5.9,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135555776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 article examines the capabilities of bulk-bitwise PIM by constructing PIMDB, a fully-digital system based on memristive stateful logic, utilizing and focusing on in-memory bulk-bitwise operations, designed to accelerate a real-life workload: analytical processing of relational databases. We introduce a host processor programming model to support bulk-bitwise PIM in virtual memory, develop techniques to efficiently perform in-memory filtering and aggregation operations, and adapt the application data set into the memory. To understand bulk-bitwise PIM, we compare it to an equivalent in-memory database on the same host system. We show that bulk-bitwise PIM substantially lowers the number of required memory read operations, thus accelerating TPC-H filter operations by 1.6×–18× and full queries by 56×–608×, while reducing the energy consumption by 1.7×–18.6× and 0.81×–12× for these benchmarks, respectively. Our extensive evaluation uses the gem5 full-system simulation environment. The simulations also evaluate cell endurance, showing that the required endurance is within the range of existing endurance of RRAM devices.","PeriodicalId":13156,"journal":{"name":"IEEE Transactions on Emerging Topics in Computing","volume":"12 1","pages":"7-22"},"PeriodicalIF":5.9,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135551143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 proposed PE design takes advantage of the properties of RNS and Canonical Signed Digit (CSD) encoding to achieve higher energy efficiency and effective processing rate, without requiring any compression mechanism or introducing any approximation. An extensive design space exploration for various parameters (RNS base, PE micro-architecture, encoding) using analytical models as well as experimental results from CNN benchmarks is conducted and the various trade-offs are analyzed. A complete end-to-end RNS accelerator is developed based on the proposed PE.

In these systems, a stochastic bit-stream encodes a data sample. The derived bit-stream is used for processing. The bit-stream length determines the computation latency for bit-serial implementations and hardware complexity for bit-parallel ones. Noise shaping is a feedback technique that moves the quantization noise outside the bandwidth of interest of a signal. This article proposes a technique that builds on noise shaping and reduces the length of the stochastic bit-stream required to achieve a specific Signal-to-Quantization-Noise Ratio (SQNR). The technique is realized by digital units that encode binary samples into stochastic streams, hereafter called as binary-to-stochastic converters. Furthermore, formulas are derived that relate the bit-stream length reduction to the signal bandwidth. First-order and second-order converters that implement the proposed technique are analyzed. Two architectures are introduced, distinguished by placing a stochastic converter either inside or outside of the noise-shaping loop. The proposed bit-stream length reduction is quantitatively compared to conventional binary-to-stochastic converters for the same signal quality level. Departing from conventional approaches, this article employs bit-stream lengths that are not a power of two, and proposes a modified stochastic-to-binary conversion scheme as a part of the proposed binary-to-stochastic converter. Particularly, SQNR gains of 29.8 dB and 42.1 dB are achieved for the first-order and second-order converters compared to the conventional converters for equal-length bit-streams and low signal bandwidth. The investigated converters are designed and synthesized at a 28-nm FDSOI technology for a range of bit widths.","PeriodicalId":13156,"journal":{"name":"IEEE Transactions on Emerging Topics in Computing","volume":"11 4","pages":"1002-1017"},"PeriodicalIF":5.9,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62529127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Graph processing is a powerful tool to model and optimize complex problems where graph-based data is involved. In consideration of the relatively insufficient resource provisioning of the edge devices, in this article, for the first time to our knowledge, we propose a reliable edge-cloud collaboration framework that facilitates the graph primitives based on a lightweight interactive graph processing library (GPL), especially for shortest path search (SPS) operations as the demonstrative example. Two types of different practical cases are also presented to show the typical application scenarios of our graph processing strategy. Experimental evaluations indicate that the acceleration rate of performance can reach 6.87x via graph reduction, and less than 3% and 20% extra latency is required for much better user experiences for navigation and pandemic control, respectively, while the online security measures merely consume about 1% extra time of the overall data transmission. Our framework can efficiently execute the applications with considering of user-friendliness, low-latency response, interactions among edge devices, collaboration between edge and cloud, and privacy protection at an acceptable overhead.","PeriodicalId":13156,"journal":{"name":"IEEE Transactions on Emerging Topics in Computing","volume":"11 4","pages":"985-1001"},"PeriodicalIF":5.9,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62529060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 low-power, reduced computing capacity of the IoT device makes public-private, certificate-based forms of authentication impractical, while other lighter-weight, symmetric cryptography-based approaches, such as message authentication codes, are easy to spoof in unsupervised environments where adversaries have direct physical access to the device. Such environments are better served by security primitives rooted in the hardware with capabilities exceeding those available in cryptography-only frameworks. A key foundational hardware security primitive is the physical unclonable function or PUF. PUFs are well known for removing the need to store secrets in secure non-volatile memories, and for providing very large sets of authentication credentials. In this article, we describe two PUF-based mutual authentication protocols rooted in the entropy provided by a strong PUF. The security properties of the authentication protocols, called COBRA and PARCE, are evaluated in hardware experiments on SoC-based FPGAs, and under extended industrial-standard operating conditions. A codesign-based system architecture is presented in which the SiRF PUF and core authentication functions are implemented in the programmable logic as a secure enclave, while network and database operations are implemented in software on an embedded microprocessor.","PeriodicalId":13156,"journal":{"name":"IEEE Transactions on Emerging Topics in Computing","volume":"11 4","pages":"918-933"},"PeriodicalIF":5.9,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62529012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
