Improving development environment for embedded software

내장 소프트웨어를 위한 개발 환경의 개선

RFID systems have been widely used in various fields such as logistics, distribution, food, security, traffic and others. A RFID middleware, one of the key components of the RFID system, perform an important role in many functions such as filtering, grouping, reporting tag data according to given user specifications and so on. However, manual test data generation is very hard because the inputs of the RFID middleware are generated according to the RFID middleware standards and complex encoding rules. To solve this problem, in this paper, we propose a black box test technique based on RFID middleware standards. Firstly, we define ten types of input conversion rules to generate new test data from existing test data based on the standard specifications. And then, using these input conversion rules, we generate various additional test data automatically. To validate the effectiveness of generated test data, we measure coverage of generated test data on actual RFID middleware. The results show that our test data achieve 78% statement coverage and 58% branch coverage in the classes of filtering and grouping, 79% statement coverage and 64% branch coverage in the classes of reporting.

기계장치에 내장되어 동작하는 내장 소프트웨어의 개발 환경은 일반 소프트웨어와 비교하여 불편한 점이 많다. 소프트웨어가 개발되는 장비와 동작하는 장비가 다르며 일반적으로 고가의 상용 개발도구를 필요로 한다. 본 논문은 공개 소프트웨어 도구들을 활용하여 내장 소프트웨어의 개발환경을 개선시킬 수 있는 방안을 제시한다. cross compile을 위한 GNU Compiler Collection과 Scratch box, 통합 개발 환경인 Eclipse, 원격 접속을 위한 RSE, 가상화를 위한 QEMU 등의 특징과 효과적인 활용 방법을 설명한다.
