Abstract
본 발명은 두개의 프로세서간의 실시간 제어를 위한 동기화 장치에 관한 것이다. 실시간 제어를 위하여 메인 프로세서는 타이머로 부터 일정 시간 간격마다 발생되는 타이밍 펄스에 의해 인터럽트되며, 인터럽트 때마다 서브프로세서와의 동기를 위한 인터럽트 신호를 발생한다. 서브프로세서는 메인프로세서에 의해 인터럽트될 때마다 공유 메모리에 메인 프로세서로 제공될 데이타를 저장한다. 메인 프로세서는 서브 프로세서에서 발생되는 서브 프로세서의 인터럽트 신호에따라, 서브 프로세서에 제공될 데이타를 공유 메모리에 저장한다. 공유 메모리에 저장된 데이터는 각각의 메인 프로세서 및 서브 프로세서에 의해 판독되어 실시간으로 처리된다.The present invention relates to a synchronization device for real time control between two processors. For real-time control, the main processor is interrupted by a timing pulse generated at regular time intervals from the timer, and generates an interrupt signal for synchronizing with the subprocessor at each interrupt. Each time a subprocessor is interrupted by the main processor, it stores data to be provided to the main processor in shared memory. The main processor stores data to be provided to the subprocessor in the shared memory according to the interrupt signal generated by the subprocessor. Data stored in the shared memory is read by each main processor and subprocessor and processed in real time.
