A model's goal is to recommend a set of modules to receive special treatment. The purpose of the paper is to report our experiences modeling software quality with classification trees, including necessary preprocessing of data. We conducted a case study on two releases of a very large legacy telecommunications system. A module was considered fault-prone if any faults were discovered by customers, and not fault-prone otherwise. Software product, process, and execution metrics were the basis for predictors. The TREEDISC algorithm for building classification trees was investigated, because it emphasizes statistical significance. Numeric data, such as software metrics, are not suitable for TREEDISC. Consequently, we transformed measurements into discrete ordinal predictors by grouping. This case study investigated the sensitivity of modeling results to various groupings. We found that robustness, accuracy, and parsimony of the models were influenced by the maximum number of groups. Models based on two sets of candidate predictors had similar sensitivity.","PeriodicalId":193867,"journal":{"name":"Proceedings IEEE International Conference on Software Maintenance - 1999 (ICSM'99).

Scott, Tim Womack","doi":"10.1109/ICSM.1999.792629","DOIUrl":"https://doi.org/10.1109/ICSM.1999.792629","url":null,"abstract":"Digital signal processors (DSPs) are special purpose microprocessors optimised for embedded applications that require high arithmetic rates. These devices are often difficult to compile for; compared to modern general purpose processors, DSPs often have very small address spaces. In addition they contain unusual hardware features and they require correct scheduling of operands against pipeline registers to extract the highest levels of available performance. As a result, high level language compilers for these devices generate poor quality code, and are rarely used in practice. Recently, new generation processors have been launched that are very hard to program by hand in assembler because of the complexity of their internal pipelines and arithmetic structures. DSP users are therefore having to migrate to using high level language compilers since this is the only practical development environment. However, there exist large quantities of legacy code written in assembler which represent a significant investment to the user who would like to be able to deploy core algorithms on the new processors without having to re-code from scratch. The article discusses the development and use of a tool to automatically reverse-compile assembler source for the ADSP-21xx family of DSPs to ANSI-C. We include a discussion of the architectural features of the ADSP-21xx processors and the ways in which they assist the translation process. We also identify a series of translation challenges which, in the limit, can only be handled with manual intervention and give some statistics for the frequency with which these pathological cases appear in real applications.","PeriodicalId":193867,"journal":{"name":"Proceedings IEEE International Conference on Software Maintenance - 1999 (ICSM'99).

Traditionally, this information is obtained via manual examination of configuration files and the source code directory hierarchy. However both types of artifact are limited in distinguishing which modules are used exclusively by each executable component. This exclusivity distinction is important in that it helps to understand the components' unique functionalities and their potential runtime behaviour. This paper presents a module classification technique that can facilitate automatic recognition of executable component modules in a distributed system. In contrast to existing approaches, the technique explicitly distinguishes component exclusive modules from modules shared by multiple components. The paper illustrates the benefits of the technique by reporting on the results of a case study where it has been useful to (a) revealing component exclusive modules in the source code for the field distributed programming environment; and (b) investigating some aspects of an implicit-invocation model of field described elsewhere. Applications of the technique to other software engineering tasks, such as change impact analysis, reuse and restructuring, are also discussed.","PeriodicalId":193867,"journal":{"name":"Proceedings IEEE International Conference on Software Maintenance - 1999 (ICSM'99).
