High-Level Methods for Hardware IP Protections: Solutions, Trends, and Challenges
Full text linkDue to the globalization of the semiconductor supply chain, the security threats for the production of an integrated circuit (IC) and its intellectual property (IP) are becoming more and more critical for many fab-less design houses. Conversely, the protections for these threats are expensive, especially when introduced in the last stages of the design flow. In this paper, we discuss the approaches, the trends, and the associated challenges that can be applied in the early stages of the design, i.e., before logic synthesis. On one hand, these approaches can operate on more semantic information and offer more protection. On the other hand, they have more effects on the overall design and need to somehow 'predict' the effects on the final implementation
Towards High-Level Synthesis of Quantum Circuits
Full text linkIn recent years, there has been a proliferation of quantum algorithms, primarily due to their exponential speedup over their classical counterparts. Quantum algorithms find applications in various domains, including machine learning, molecular simulation, and cryptography. However, extensive knowledge of linear algebra and quantum mechanics are required to program a quantum computer, which might not be feasible for traditional software programmers. Moreover, current quantum programming paradigm is difficult to scale and integrate quantum circuits to achieve complex functionality. To this end, in this paper, we introduce QHLS, a quantum high-level synthesis (HLS) framework. To the best of our knowledge, this is the first HLS framework for quantum circuits. The proposed QHLS allows quantum programmers to start with high-level behavioral descriptions (e.g., C, C++) and automatically generate the corresponding quantum circuit; thus, reducing the complexity of programming a quantum computer. Our experimental results demonstrate the success of QHLS in translating high-level behavioral software programs containing arithmetic, logical, and conditional statements
QHLS: An HLS Framework to Convert High-Level Descriptions to Quantum Circuits
Full text linkQuantum Computing has been shown to provide exponential performance improvements in several tasks, such as cryptography, healthcare, etc. This paper presents a new framework for quantum high-level synthesis, called QHLS, that aims to facilitate programmers using quantum computers. Currently, quantum-computer programmers need extensive linear algebra and quantum mechanics knowledge, which can be challenging for traditional software programmers. Additionally, the current quantum programming paradigm is not scalable, and it can be difficult to combine quantum circuits to create a more complex functionality. QHLS addresses these issues by enabling the automatic generation of quantum circuit descriptions directly from high-level behavioral specifications (using languages like C or C++). This simplifies the programming of a quantum computer, making it more accessible to a wider range of programmers. Our experiments show that QHLS can successfully translate high-level software programs containing various types of statements (such as arithmetic, logical, and conditional operations) into functionally equivalent quantum circuits
A Survey of FPGA Optimization Methods for Data Center Energy Efficiency
Full text linkThis article provides a survey of academic literature about field programmable gate array (FPGA) and their utilization for energy efficiency acceleration in data centers. The goal is to critically present the existing FPGAs energy optimization techniques and discuss how they can be applied to such systems. To do so, the article explores current energy trends and their projection to the future with particular attention to the requirements set out by the European Code of Conduct for Data Center Energy Efficiency. The article then proposes a complete analysis of over ten years of research in energy optimization techniques, classifying them by purpose, method of application, and impacts on the sources of consumption. Finally, we conclude with the challenges and possible innovations we expect for this sector
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
