UltraSPARC is the first microprocessor from Sun Microsystems' SPARC Technology Business to implement the new 64-bit SPARC V9 architecture. ULtraSPARC is equipped with unique multimedia capabilities and is capable of 4-way superscalar instruction dispatch, with an emphasis on maximal system efficiency and throughput in the execution of complex,(More)
The overall CAD methodology for the design of UltraSPARC-I microprocessor at Sun is described in this paper. Topics discussed include: CAD flow strategy, tool development and integration strategy, and design infrastructure. The importance of concurrent design style, modular CAD flow environment , incremental design verification and early design quality(More)
We have developed a novel double Amplification Refractory Mutation System (double ARMS) using a highly polymorphic region 5' to the human delta-globin gene as a model system. The double ARMS approach involves using two allele-specific ARMS primers simultaneously during DNA amplification by the polymerase chain reaction (PCR). The resulting system is highly(More)
Texts detection from image or complex colored document is a very challenging problem. Text in images and videos contain useful information. There is a significant need to extract and analyze the text in images on Web documents, for effective indexing, semantic analysis and searching. The extraction of text information is very important because texts contain(More)
BACKGROUND Many brain imaging techniques interpret the haemodynamic response as an indirect indicator of underlying neural activity. However, a challenge when interpreting this blood based signal is how changes in brain state may affect both baseline and stimulus evoked haemodynamics. NEW METHOD We developed an Automatic Brain State Classifier (ABSC),(More)
Improvements of robustness of speech recognition is one of the hottest topics in speech signal processing, particularly when applied within a noisy environment. Most of the research efforts focused in combining audio and visual data to implement an audiovisual speech recognition (AVSR) system. Bimodal approach demonstrated that a superior performance can be(More)
BACKGROUND Atrial fibrillation is associated with higher mortality. Identification of causes of death and contemporary risk factors for all-cause mortality may guide interventions. METHODS AND RESULTS In the Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial(More)
