Digital circuits often have a critical path that runs through a small subset of the component subblocks, but where the path changes dynamically during operation. Dynamically resizable static CMOS (DRCMOS) logic is proposed as a fine-grain leakage reduction technique that dynamically downsizes transistors in inactive subblocks while maintaining speed in subblocks along the current critical path....

Determining the means by which an attacker may compromise a given system is the main purpose of vulnerability assessment. As such, there are several models currently in place to track vulnerabilities. Some models focus on the susceptibility of a computer system as a whole where other models track attack paths through a network. This paper proposes a model which accomplishes both. The primary fo...

Process variation reduces a pipeline’s maximum attainable frequency by creating unbalance in the stage delays. As a result, the pipeline ends up cycling with a period close to that of the slowest pipeline stage. ReCycle was proposed in ISCA 2007 as a framework for comprehensively applying cycle time stealing to balance the stage delays under process variation, thereby allowing the pipeline to c...

Abstract:The VLSI design industry has grown rapidly during the last few decades. The complexity of the applications increases day by day due to which the area utilization increases. The tradeoff between area and speed is an important factor. The main focus of continued research has been to increase the operating speed by keeping the area and memory utilization of the design as low as possible. ...

The present technology for designing, manufacturing, and installing equipment foundations and systems is labor ...

Critical path method is a network based method planned for development and organization of complex project in real world application. In this paper, a new methodology has been made to find the critical path in a directed acyclic graph, whose activity time uncertain. The vague parameters in the network are represented by intuitionistic triangular fuzzy numbers, instead of crisp numbers. A new pr...

This study proposes that the entropy function provides a simple and useful tool for project managers to better cope with project uncertainty, and therefore better manage projects. The entropy function has a long and established history as a measure of uncertainty in information theory. If selected activities on PERT networks are modified by reducing their activity times by one or more time unit...

The purpose of the critical path method (CPM) is to identify the critical activities in the critical path of an activity network. In the real world for many projects we have to use human judgment for estimating the duration of activities. However, the unknowns or vagueness about the time duration for activities in network planning, has led to the development of fuzzy CPM. A way to deal with thi...

The Critical Path Method (CPM) is a vital tool for the planning and control of complex projects. The successful implementation of CPM requires the availability of a clear determined time duration for each activity. However, in practical situations this requirement is usually hard to fulfill since many of activities will be executed for the first time. Hence, there is always uncertainty about th...

A full digital self-timed clock generation scheme is developed, where multiple internal clocks are self-generated for each external request. The internal clock period is designed to be the critical path delay of the internal system at all operating environments. This scheme can be applied to time-multiplexed implementations, self-timed operation , and low-power applications.
