The virtual channel flow control (VCFC) provides an efficient implementation for on-chip networks. However, allocating the virtual channels (VCs) uniformly results in a waste of area and significant leakage power, especially at nanoscale. To remedy this situation, we propose a novel approach for customizing the virtual channels allocation based on the(More)
In this paper, we develop a new methodology for designing a lower-error and area-time efficient 2 s-complement fixed-width Booth multiplier that receives two n-bit numbers and produces an n-bit product. By properly choosing the generalized index and binary thresholding, we derive a better error-cojmpensation bias to reduce the truncation error. Since the(More)
In this paper, intra-chip design has long been the main research area for the past years, resulting in several folds of computing power increase per year. In contrast, the speed of cross-chip connection, or even cross-system connection, has not been enhanced at the same rate, and gradually became the bottleneck of current computing systems. PCI, PCI-X, and(More)
BACKGROUND Despite limited evidence, postoperative prophylactic antibiotics are often used in the setting of permanent pacemaker implantation or replacement. The aim of this study is to investigate the efficacy of postoperative antibiotics. HYPOTHESIS Postoperative prophylactic antibiotics may be not clinically useful. METHODS We recruited 367(More)
Upper gastrointestinal (UGI) bleeding is the most frequently encountered complication of peptic ulcer disease. Helicobacter pylori (Hp) infection and nonsteroidal anti-inflammatory drug (NSAID) administration are two independent risk factors for UGI bleeding. Therefore, testing for and diagnosing Hp infection are essential for every patient with UGI(More)
