Adaptive Approximate Computing in Arithmetic Datapaths
Volume PP - IEEE Computer Society

Approximate adders and multipliers are often equipped with Error Detection and Correction (EDC) for accuracy configurability during application runtime. Traditionally, EDC is controlled by user inputs at the component level. In this paper, we propose an adaptive approximate...

Enabling Rapid Construction of Arrival Curves From Execution Traces
Volume PP - IEEE Computer Society

Arrival curves are a widely used abstraction for modeling temporal workloads in real-time systems. Multiple frameworks derived from Network Calculus theory operate over arrival curves to perform exhaustive analysis of real-time systems at design-time. While there is extensive...

Design and Implementation of an Overlay File System for Cloud-Assisted Mobile Apps
Volume PP - IEEE Computer Society

With cloud assistance, mobile apps can offload their resource-demanding computation tasks to the cloud. This leads to a scenario where computation tasks in the same program run concurrently on both the mobile device and the cloud. An important challenge is to ensure that the tasks are...

Self-Test and Diagnosis for Self-Aware Systems Survey for Design & Test Special Issue on “Self-Awareness in SoCs”
Volume PP - IEEE Computer Society

Self-awareness allows autonomous systems the dynamic adaptation to changing states of the hardware platform and the optimal usage of available computing resources. This demands concurrent, periodical, or on-demand monitoring and testing of the hardware structures to detect...

Safe and Efficient Deployment of Data-Parallelisable Applications on Many-Core Platforms: Theory and Practice
Volume PP - IEEE Computer Society

The safe and, at the same time, efficient deployment of parallelisable applications on many-core platforms is a challenging task. Theoretical Models of Computation (MoC) require the realistic estimation of task Worst-Case Execution Time (WCET) to provide safe latency guarantees...

Testing real-time systems with runtime enforcement
Volume PP - IEEE Computer Society

When testing a time-critical system, some scenarios can be hard to run when acting only on the input sequence. The proper execution of a given scenario might require for instance a minimal execution time for a given piece of software. Execution times are notoriously difficult...

ADAGE: Automatic DfT-Assisted Generation of Test Stimuli for Mixed-Signal Integrated Circuits
Volume PP - IEEE Computer Society

This paper presents a new method to automate the testing of analog and mixed-signal integrated circuits. The proposed workflow, called ADAGE, combines two methods from literature: the topology modification technique and the automatic test signal generation based...

An Automated Low-Cost Analog and Mixed-Signal DfT Method Using Testing Diodes
Volume PP - IEEE Computer Society

The quality level of the analog parts in mixedsignal ICs lags behind the below-part-per-million escape rates of the digital core. The reason is that analog blocks in these ICs have high test escape rates as a result of the typical testing based on performance specifications. Test point...

Privacy-Preserving Outsourced Support Vector Machine Design for Secure Drug Discovery
Volume PP - IEEE Computer Society

In this paper, we propose a framework for privacy-preserving outsourced drug discovery in the cloud, which we refer to as POD. Specifically, POD is designed to allow the cloud to securely use multiple drug formula providers' drug formulas to train Support Vector Machine (SVM) provided...

An Empirical Set of Metrics for Embedded Systems Testing
Volume PP - IEEE Computer Society

Embedded systems are ad-hoc combinations of computer hardware and software. Usually, testing activities of their performance are focused on different criteria such as execution times, energy consumption, and reliability. This paper deals with a new empirical set of metrics...
