Abstract

기존의 모든 통신은 1개의 시리얼통신라인을 이용해 다른 시스템과의 연결에 모두 사용되고 있다. 그러나 이런 경우 예를들어 CPUB는 CPUA로부터 명령을 수신하여 수신한 처리데이타에 대한 동작결과를 CPUA로 전송한다.All existing communications are used for connection to other systems using a single serial communication line. However, in this case, for example, CPU B transfers the operation result to the data reception processing to receive a command from the CPU to the CPU A A.

그런데 이런 경우에는 CPUA와 CPUB사이에는 명령과 동작결과에 대한 데이타를 사용할 수 없어 두 시스템(CPUA, CPUB)간의 동작에 많은 영향을 미치게 된다.However, this case is not available for data for a command to the operation result between the CPU A and CPU B will effect a significant effect on the operation between the two systems (CPU A, CPU B).

그리하여 본 발명은 하나의 시리얼통신라인을 다용도로 활용하는 알고리즘을 제공해 주므로써 두 시스템(CPUA, CPUB)간의 동작에 영향을 미치고 않고 CPUA의 디버깅메세지와 같은 추가적은 데이타를 PC에서 수신하여 모니터링시킬 수 있게 하는데 있다.Thus, the present invention provides an algorithm that utilizes a single serial communication line in a versatile manner, so that it does not affect the operation between the two systems (CPU A and CPU B ) and receives a small amount of data, such as a debug message of the CPU A , To be monitored.
