Abstract

데이타 처리장치(3)는 외부개발시스템(7)이 내부 버스의 유형 또는 사용 가능성을 가정하지 않고서 그리고 데이타 처리장치(3)의 효율과 속도에 심히 영향을 끼치지 않고서 데이타 처리장치(3)의 내부 연산을 동적으로 관찰하도록 허용하는 실시간 트레이스 함수를 실행한다. 데이타 처리장치(3)의 디버그 모듈(10)은, DDATA 신호와 PST 신호를 매개로하여 내부 연산 정보를 제공하기 위한 병렬 출력 포트(port)를 제공한다. 상기 DDATA 신호는 오퍼랜드 값을 반영하는 데이타를 제공하고 상기 PST 신호는 중앙처리장치(2)의 실행상태를 반영하는 코드화된 상태 정보를 제공한다. 더욱이 , 상기 DDATA 신호는 또한 포착된 명령 어드레스 프로그램 흐름 변화를 제공하여 외부개발 시스템(7)이 외부에서 가시가능한 어드레스 버스 또는 외부에서 가시가능한 데이타 버스를 필요치 않고서도 정확한 프로그램 흐름을 추적하게 된다.
