The increasing gap in performance between processors and main memory has made effective instructions prefetching techniques more important than ever. A major deficiency of existing prefetching methods is that most of them require an extra port to I-cache. A recent study by [19] shows that this factor alone explains why most modern microprocessors do not use(More)
A hardware method for functional unit assignment is presented, based on the principle that a functional unitýs power consumption is approximated by the switching activity of its inputs. Since computing the Hamming distance of the inputs in hardware is expensive, only a portion of the inputs are examined. Integers often have many identical top bits, due(More)
Code size is an important concern in embedded systems. VLIW architectures are popular for embedded systems, but often increase code size, by requiring NOPs to be inserted into the code to satisfy instruction placement constraints. Existing VLIW instruction schedulers target run-time but not code size. Indeed, current schedulers often increase code size, by(More)
Recently, the interests in proteomics have been intensively increased, and the proteomic methods have been widely applied to many problems in cell biology. If the age of 1990s is considered to be a decade of genomics, we can claim that the following years of the new century is a decade of proteomics. The rapid evolution of proteomics has continued through(More)
Nowadays, multimedia services over wireless networks are increasingly popular. With multicast, many mobile stations can join the same video group and share the same radio resource to efficiently increase frequency utilization. However, users may be located at different positions, and so suffer different degrees of path loss and interference, and receive a(More)
Peer-to-peer (P2P) File delivery systems of distributed computing are designed with the understanding that any peer can leave the network at any time, often right after completing its download. The conventional approach to P2P scheduling, shortest processing-time first, is not well suited to peer-leaving situations. We therefore propose a new scheduling(More)
The last few decades have seen the rise of widely-available proteomics tools. From new data acquisition devices, such as MALDI-MS and 2DE to new database searching softwares, these new products have paved the way for high throughput microbial proteomics (HTMP). These tools are enabling researchers to gain new insights into microbial metabolism, and are(More)
Although CMOS is the most popular technology for integrated circuits, a disadvantage is that it requires both NMOS and PMOS transistors. In contrast, this paper describes a new unipolar CMOS technology that replaces the PMOS transistor with a modified NMOS containing an elevated body and two embedded oxides (EBTEO). This modified NMOS makes use of the(More)
