On-chip L1 and L2 caches represent a sizeable fraction of the total power consumption of microprocessors. In deep sub-micron technology , the subthreshold leakage power is becoming the dominant fraction of the total power consumption of those caches. In this paper, we present optimization techniques to reduce the leakage power of on-chip caches assuming that there are multiple threshold voltage...

the relationship between economic growth and developments in the ‎financial sector has been one of the most discussed areas in economics ‎for a long time; and the direction of causality – whether financial ‎development causes economic growth or vice versa – is by no means a ‎settled issue.‎this paper investigates the short- run and long-run granger causality ‎between financial development and e...

Many important software systems are written in the C programming language. Unfortunately, the C language does not provide strong safety guarantees, and many common programming mistakes introduce type errors that are not caught by the compiler. These errors only manifest themselves at run time through unexpected program behavior, and it is often hard to isolate and identify their causes. This pa...

The relationships between coupling and external quality factors of object-oriented software[1] have been studied extensively for the past few years. For example, a clear empirical relationship between class-level coupling and the fault-proneness of the classes have been identified by several studies. A number of statistical techniques, principally Agglomerative Hierarchical Clustering (AHC) ana...

The ability of system software to detect and issue error messages that help programmers quickly fix serial and parallel run-time errors is an important productivity criterion for developing and maintaining application programs. Over ten thousand run-time error tests and a run-time error detection (RTED) evaluation tool has been developed for the automatic evaluation of run-time error detection ...

This thesis describes the design, implementation and use of a run-time debugging tool for understanding the lazy semantics and locating failures in the functional logic language Curry. We provide a means for programmers to step in the evaluation order of program expressions at a source code level. Every expression evaluated is detected by a program coverage in a layout of the source code. Its r...
