An Efficient C++ Framework for Cycle-Based Simulation
نویسنده
چکیده
System design usually begins with a high-level software simulation which is later refined to a detailed hardware description. A simulation framework can facilitate this process by automating certain hardware abstractions, providing important debugging support, and allowing the transition from a high-level simulation to a low-level hardware description to occur within a single code base. This paper discusses our experience with Sim, a C++ framework developed as an internal tool for cycle-based simulations. We describe the features of Sim which were found to be most helpful to the design process, and we compare Sim to a publicly available simulation framework. The Sim framework is efficient; typical lowlevel hardware simulations run with a slowdown of less than 2x compared to straight C++ implementations.

A Hybrid Framework for Building an Efficient Incremental Intrusion Detection System
In this paper, a boosting-based incremental hybrid intrusion detection system is introduced. This system combines incremental misuse detection and incremental anomaly detection. We use boosting ensemble of weak classifiers to implement misuse intrusion detection system. It can identify new classes types of intrusions that do not exist in the training dataset for incremental misuse detection. As...

In this paper, an efficient method is presented to control the attitude of a satellite with ON-OFF actuator. The main objective of this novel method is to control the amplitude of the limit cycle which commonly appears in the steady state of such systems; and at the same time by consideration of real actuator constraints, reduce the fuel consumption of system. The Proposed method is a combinati...
متن کاملAn integrated simulation-DEA approach to multi-criteria ranking of scenarios for execution of operations in a construction project
The purpose of this study is to examine different scenarios for implementing operations in the pre-construction phase of a project, based on several competing criteria with different importance levels in order to achieve a more efficient execution plan. This paper presents a new framework that integrates discrete event simulation (DES) and data envelopment analysis (DEA) to rank different scena...

متن کاملA JOINT DUTY CYCLE SCHEDULING AND ENERGY AWARE ROUTING APPROACH BASED ON EVOLUTIONARY GAME FOR WIRELESS SENSOR NETWORKS
Network throughput and energy conservation are two conflicting important performance metrics for wireless sensor networks. Since these two objectives are in conflict with each other, it is difficult to achieve them simultaneously. In this paper, a joint duty cycle scheduling and energy aware routing approach is proposed based on evolutionary game theory which is called DREG. Making a trade-off ...
