This article presents a novel Parallel Deadlock Detection Algorithm (PDDA) and its hardware implementation, Deadlock Detection Unit (DDU). PDDA uses simple Boolean representations of request, grant, and no activity so that the hardware implementation of PDDA becomes easier and operates faster. We prove the correctness of PDDA and that the DDU has a runtime(More)
Numerous monitoring applications such as traffic control systems, border patrol monitoring, and person locater services generate a large number of multimedia data streams that need to be analyzed and processed using image processing and data stream management techniques in order to detect significant events of interest or abnormal conditions. Such(More)
In this demo, we present the StreamFitter system for real-time regression analysis on continuous data streams. In order to perform regression on data streams, it is necessary to continuously update the regression model parameters while receiving new data. In this demo, we will present two approaches for on-line, multi-dimensional linear regression analysis(More)
— Future high performance computing systems may consist of multiple processors and reconfigurable logic co-processors. As indicated by industry trends, such co-processors will be integrated on existing motherboards without any glue logic. It is likely that such hybrid computing machines will be a breakthrough for various high performance applications. As a(More)
