Abstract

As most embedded applications are realized in software, software

performance estimation is a very important issue in embedded system design. In the last decades, instruction set simulators (ISSs) have become an essential part of an embedded software design process. However, ISSs are either slow or very difficult to develop. With the advent of multiprocessor systems and their ever-increasing complexity, the software simulation strategy based on ISSs is no longer efficient enough for exploring the large design space of multiprocessor systems in early design phases. Motivated by the limitations of ISSs, a lot of recent research activities focused on software simulation strategies based on native execution. In this article, we first introduce some existing software performance simulation strategies as well as our own approach for source level simulation, called SciSim, and provide a discussion about their benefits and limitations. The main contribution of this article is to introduce a new software performance simulation approach, called iSciSim (intermediate Source code instrumentation based Simulation), which achieves high estimation accuracy, high simulation speed and low

implementation complexity. All these advantages make iSciSim well-suited for system level design. To show the benefits of the proposed approach, we present a quantitative comparison between iSciSim and the other discussed techniques, using a set of benchmarks.

Abstract

The purpose of this study was to determine Iranian EFL teachers’ level of computer anxiety and its relationship with ICT integration into English classes and teachers’ personal characteristics. Data were collected from 254 Iranian EFL teachers by Computer Anxiety Rating Scale, ICT integration rating scale, and a personal information questionnaire. The results indicated a positive relationship between computer anxiety and age; however, computer anxiety, gender, and experience of teaching were not found to be related. An inverse correlation was found between computer anxiety and ICT integration. While ICT integration correlated negatively with age and years of teaching experience, it was not found to be related to gender.

Abstract

Spatial Analysis and Decision Assistance (SADA) is a Windows freeware program that incorporates spatial assessment tools for effective environmental remediation. The software integrates modules for GIS, visualization, geospatial analysis, statistical analysis, human health and ecological risk assessment, cost/benefit analysis, sampling design, and decision support. SADA began as a simple tool for integrating risk assessment with spatial modeling tools. It has since evolved into a freeware product primarily targeted for spatial site investigation and soil remediation design, though its

applications have extended into many diverse environmental disciplines that emphasize the spatial distribution of data. Because of the variety of algorithms incorporated, the user interface is engineered in a consistent and scalable manner to expose additional functionality without a burdensome increase in complexity. The scalable environment permits it to be used for both application and research goals, especially investigating spatial aspects important for estimating environmental exposures and designing efficient remedial designs. The result is a mature infrastructure with considerable environmental decision support capabilities. We provide an overview of SADA’s central functions and discuss how the problem of integrating diverse models in a tractable manner was addressed.

Research highlights

► SADA is mature software for data visualization, processing, analysis, and modeling. ► User interface balances functional scalability and decision support. ► Widely used due to free availability and shallow learning curve. ► Integration of spatial estimation and risk tools allows for rich decision support.
