ÐApplication specific instructions play an important role in reducing the required code size and increasing performance in embedded DSP systems. This paper describes a new approach to generate application specific instructions for DSP applications. The proposed approach is based on a modified subset-sum problem and supports multicycle complex instructions,(More)
—Future inter-and intra-ULSI interconnect systems demand extremely high data rates (up to 100 Gbps/pin or 20-Tbps aggregate) as well as bidirectional multiI/O concurrent service, re-configurable computing/processing architecture, and total compatibility with mainstream silicon system-on-chip and system-in-package technologies. In this paper, we review(More)
This paper describes the MetaCore system which is an ASIP (Application-Specific Instruction set Processor) development system targeted for DSP applications. The goal of MetaCore system is to offer an efficient design methodology meeting specifications given as a combination of performance, cost and design turnaround time. MetaCore system consists of two(More)
In this paper, Network-based Embedded core Testing (NET) architecture is proposed. The test of individual embedded cores and their interconnection are possible in a System-on-Chip (SoC) environment by using configurable On-Chip Network (OCN) architecture. And the test time can be reduced because the proposed test access mechanism provides high bandwidth for(More)
A self-synchronized RF-interconnect (SSRFI), based on capacitive coupling and peak signal detection, is presented. In this SSRFI, small coupling capacitor (6 0 s) is used to interconnect vertical active layers in 3-Dimensional IC. The demonstrated SSRFI system, including both transmitter and receiver, has heen designed, fabricated and verified in UMC 0. 1 8(More)
BACKGROUNDS Expression of Livin, a member of the inhibitors of apoptosis protein family, is associated with tumor development and progression. The aims of this study were to evaluate whether Livin affects oncogenic biological behavior of colorectal cancer cells, and to document the relationship between its expression and various clinicopathological(More)
Cement grouted soils, which consist of particulate soil media and cementation agents, have been widely used for the improvement of the strength and stiffness of weak ground and for the prevention of the leakage of ground water. The strength, elastic modulus, and Poisson's ratio of grouted soils have been determined by classical destructive methods. However,(More)
PURPOSE Previous studies have reported that over a third of cancer patients experience significant psychological distress with diagnosis and treatment of cancer. Mental adjustment to cancer as well as other biologic and demographic factors may be associated with their distress. We investigated the relationship between mental adjustment and distress in(More)
Interleukin-18 (IL-18) is a pleiotropic, pro-inflammatory cytokine that is capable of promoting the Th1 response. A predominant Th1 response induces chronic and persistent inflammatory changes in the gastric mucosa in response to Helicobacter pylori (H. pylori) infection. The aim of this study was to investigate the potential association between IL-18 gene(More)
Purpose. The aim of this study was to determine the efficacy of prophylactic antibiotics (PA) for reducing the infectious complications and the potential risk factors responsible for the infectious complications after stent insertion for malignant colorectal obstruction. Methods. We performed a retrospective review of 224 patients who underwent(More)
