Data uncertainty is inherent in many real-world applications such as sensor monitoring systems, location-based services, and medical diagnostic systems. Moreover, many real-world applications are now capable of producing continuous, unbounded data st

In this article, a brand new method of determining deadlock is presented. Most previous deadlock detection methods are algorithmic in the sense that they usually leverage some forms of Resource Allocation Graph (RAG) representations and then algorith

Current MPSoCs typically consist of less than a dozen processing units. Future MPSoCs are likely to integrate many more. With this trend, dozens of applications can be running on an MPSoC concurrently and application deadlock on MPSoCs will become a

The storage model of column-oriented databases is similar in structure to densely packed matrices/vectors found in many high-performance computing applications. Hence, hardware-accelerated vectorized matrix operations using Reconfigurable Logic (RL)

Due to rapid technology advance, multiprocessor system-on-chips (MPSoCs) are likely to become commodity computing platforms for embedded applications. In the future, it is possible that an MPSoC is equipped with a large number of processing elements

Computer architecture simulation has always played a pivotal role in continuous innovation of computers. However, constructing or modifying a high quality simulator is time consuming and error-prone. Thus, often architecture description languages (AD

Given the projected dramatic increase in the number of processors and resources in a system-on-a-chip, a quadratic increase in the likelihood of deadlock is predicted due to complex system behavior. To deal with this issue, we here present a novel pa
