Security Analysis of Arbiter PUF and Its Lightweight Compositions Under Predictability Test
Phuong Ha Nguyen, Durga Prasad Sahoo, Rajat Subhra Chakraborty, Debdeep Mukhopadhyay
Article No.: 20
Unpredictability is an important security property of Physically Unclonable Function (PUF) in the context of statistical attacks, where the correlation between challenge-response pairs is explicitly exploited. In the existing literature on PUFs,...
CALM: Contention-Aware Latency-Minimal Application Mapping for Flattened Butterfly On-Chip Networks
Di Zhu, Siyu Yue, Massoud Pedram, Lizhong Chen
Article No.: 21
With the emergence of many-core multiprocessor system-on-chips (MPSoCs), on-chip networks are facing serious challenges in providing fast communication among various tasks and cores. One promising on-chip network design approach shown in recent...
Scalable SMT-Based Equivalence Checking of Nested Loop Pipelining in Behavioral Synthesis
Mohammad Reza Azarbad, Bijan Alizadeh
Article No.: 22
In this article, we present a novel methodology based on SMT-solvers to verify equality of a high-level described specification and a pipelined RTL implementation produced by a high-level synthesis tool. The complex transformations existing in the...
Optimized Implementation of Multirate Mixed-Criticality Synchronous Reactive Models
Qingling Zhao, Zaid Al-Bayati, Zonghua Gu, Haibo Zeng
Article No.: 23
Model-based design using Synchronous Reactive (SR) models enables early design and verification of application functionality in a platform-independent manner, and the implementation on the target platform should guarantee the preservation of...
Reducing the Complexity of Dataflow Graphs Using Slack-Based Merging
Hazem Ismail Ali, Sander Stuijk, Benny Akesson, Luís Miguel Pinho
Article No.: 24
There exist many dataflow applications with timing constraints that require real-time guarantees on safe execution without violating their deadlines. Extraction of timing parameters (offsets, deadlines, periods) from these applications enables the...
On the Restore Time Variations of Future DRAM Memory
Xianwei Zhang, Youtao Zhang, Bruce R. Childers, Jun Yang
Article No.: 26
As the de facto main memory standard, DRAM (Dynamic Random Access Memory) has achieved dramatic density improvement in the past four decades, along with the advancements in process technology. Recent studies reveal that one of the major...
A Hybrid DRAM/PCM Buffer Cache Architecture for Smartphones with QoS Consideration
Ye-Jyun Lin, Chia-Lin Yang, Hsiang-Pang Li, Cheng-Yuan Michael Wang
Article No.: 27
Flash memory is widely used in mobile phones to store contact information, application files, and other types of data. In an operating system, the buffer cache keeps the I/O blocks in dynamic random access memory (DRAM) to reduce the slow flash...
An Elastic Mixed-Criticality Task Model and Early-Release EDF Scheduling Algorithms
Hang Su, Dakai Zhu, Scott Brandt
Article No.: 28
Many algorithms have recently been studied for scheduling mixed-criticality (MC) tasks. However, most existing MC scheduling algorithms guarantee the timely executions of high-criticality (HC) tasks at the expense of discarding low-criticality...
Computation of Seeds for LFSR-Based n-Detection Test Generation
Article No.: 29
This article describes a new procedure that generates seeds for LFSR-based test generation when the goal is to produce an n-detection test set. The procedure does not use test cubes in order to avoid the situation where a seed does...
Scale & Cap: Scaling-Aware Resource Management for Consolidated Multi-threaded Applications
Can Hankendi, Ayse Kivilcim Coskun
Article No.: 30
As the number of cores per server node increases, designing multi-threaded applications has become essential to efficiently utilize the available hardware parallelism. Many application domains have started to adopt multi-threaded programming;...
Secure and Flexible Trace-Based Debugging of Systems-on-Chip
Jerry Backer, David Hely, Ramesh Karri
Article No.: 31
This work tackles the conflict between enforcing security of a system-on-chip (SoC) and providing observability during trace-based debugging. On one hand, security objectives require that assets remain confidential at different stages of the SoC...

Article No.: 32
This article discusses a MATLAB-to-C vectorizing compiler that exploits custom instructions, for example, for Single Instruction Multiple Data (SIMD) processing and instructions for complex arithmetic present in Application-Specific Instruction...
Scrubbing Mechanism for Heterogeneous Applications in Reconfigurable Devices
Rui Santos, Shyamsundar Venkataraman, Akash Kumar
Article No.: 33
Commercial off-the-shelf (COTS) reconfigurable devices have been recognized as one of the most suitable processing devices to be applied in nano-satellites, since they can satisfy and combine their most important requirements, namely processing...
