본 논문에서는 REX OS, Qplus, 윈도우즈 등 다양한 플랫폼을 지원하는 위피 실행 엔진의 참조 구현을 제안한다. 각 플랫폼에 따른 위피 실행 엔진의 설계 방식을 기술하고, 중복 개발을 피하기 위한 방안을 제시한다. 또한, REX OS 상에서의 링커와 로더의 구현을 설명하고, 임베디드 리눅스인 Qplus에서의 실행 엔진 구조를 기술한다. 그리고 자바 가상 머신 기반의 Jlet/MIDlet 에뮬레이터와 윈도우즈 기반의 Clet 에뮬레이터 구현 방법에 대해서 소개한다. 마지막으로 호환성 인증 도구인 PCT 및 HCT의 검증 결과와 예제 프로그램의 정상적인 작동을 통해 제안된 참조 구현의 호환성 및 완성도를 검증한다.
