Predicting software development errors using software complexitymetrics

Predictive models that incorporate a functional relationship of program error measures with software complexity metrics and metrics based on factor analysis of empirical data are developed. Specific techniques for assessing regression models are presented for analyzing these models. Within the framework of regression analysis, the authors examine two separate means of exploring the connection between complexity and errors. First, the regression models are formed from the raw complexity metrics. Essentially, these models confirm a known relationship between program lines of code and program errors. The second methodology involves the regression of complexity factor measures and measures of errors. These complexity factors are orthogonal measures of complexity from an underlying complexity domain model. From this more global perspective, it is believed that there is a relationship between program errors and complexity domains of program structure and size (volume). Further, the strength of this relationship suggests that predictive models are indeed possible for the determination of program errors from these orthogonal complexity domains     

Needed DSP software emerges

Digital signal processing (DSP) software packages are surveyed. The tools fall into two distinct categories, which correspond to the two main branches of digital signal processing: packages whose jobs are mainly signal acquisition and manipulation, and DSP programming environments. General-purpose math packages, which manipulate vectors and matrices, and can therefore perform signal processing, are also available. Digital filter design, coefficient quantization, real-time filter implementation, and code generators are discussed. A table listing the features of representative DSP packages for PCs is provided

A low-power DSP core-based software radio architecture

This paper describes an approach to developing a low-power digital signal processor (DSP) subsystem architecture for advanced software radio platforms. The architecture is intended to support next-generation wide-band spread-spectrum military waveforms. The methodology illustrates how a next-generation programmable DSP core forms the basis for an application-specific integrated circuit (ASIC). It also shows how semiconductor technologies can be integrated into such chips to achieve algorithm performance while minimizing subsystem power consumption. The ASIC is run-time configurable to maintain high flexibility. The range of RF channel modulation (“waveforms”) and air interfaces is intended to include both wide-band and traditional narrow-band waveforms. Estimated gate counts and power-consumption estimates are presented. DSP circuit-design and power-management strategies necessary to achieve low-power operation are presented. While the architecture discussion focuses on military waveforms, the approach is also applicable to commercial waveforms
