This paper presents and characterizes the Princeton Application Repository for Shared-Memory Computers (PARSEC), a benchmark suite for studies of Chip-Multiprocessors (CMPs). Previous available benchmarks for multiprocessors have focused on high-performance computing applications and used a limited number of synchronization methods. PARSEC includes emerging applications in recognition, mining and...
As the vital procedure for exploiting line segments extracted from images for solving computer vision problems, Line Segment Matching (LSM) has received growing attentions from researcher in recent years, and a considerable number of methods have been proposed. However, no one has attempted to solve two major problems in this area. The first is how to evaluate different methods in an unbiased way...
As spectral clustering has the advantage of recognizing non-convex distribution, it has been widely used in image segmentation and other areas. However, when the spectral clustering algorithm deals with large size images, in order to get the affinity matrix, it costs a lot of computation time, so its applications are limited. To solve this problem, this paper proposes a fast image segmentation algorithm...
This paper proposes a novel minimal test point insertion methodology that provisions a provably complete detection of hardware Trojans by noninvasive timing characterization. The objective of test point insertion is to break the reconvergent paths so that target routes for Trojan delay testing are specifically observed. We create a satisfiability-based input vector selection for sensitizing and characterizing...
This paper proposes Hardware Trojan (HT) placement techniques that yield challenging HT detection benchmarks. We develop three types of one-gate HT benchmarks based on switching power, leakage power, and delay measurements that are commonly used in HT detection. In particular, we employ an iterative searching algorithm to find rarely switching locations, an aging-based approach to create ultra-low...
A good benchmark suite should provide users with inputs that have multiple levels of fidelity for different use cases such as running on real machines, register level simulations, or gate-level simulations. Although input reduction has been explored in the past, there is a lack of understanding how to systematically scale input sets for a benchmark suite. This paper presents a framework that takes...
The PARSEC benchmark suite was recently released and has been adopted by a significant number of users within a short amount of time. This new collection of workloads is not yet fully understood by researchers. In this study we compare the SPLASH-2 and PARSEC benchmark suites with each other to gain insights into differences and similarities between the two program collections. We use standard statistical...
In today's networked storage environment, it is common to have a hierarchy of caches where the lower levels of the hierarchy are accessed by multiple clients. This sharing can have both positive or negative effects. While data fetched by one client can be used by another client without incurring additional delays, clients competing for cache buffers can evict each other's blocks and interfere with...
