Abstract

In this paper, shared memory feature was developed in multi-core system with different OS for different processor-specific bus, while conducting an experiment on shared memory feature between the two processors based on embedded Linux system. For the purpose of developing shared memory in dual bus structure, memory controller was used, while managing shared memory segment through list data structure. For AMP multi-core test, Linux OS was installed in 2 processor cores. In addition, it verified the creation and use of shared memory by using kernel module implemented to test shared memory.

본 논문에서는 프로세서별 서로 다른 버스에 서로 다른 운영체제를 갖는 멀티코어 시스템에서 공유 메모리 기능을 구현하고, 임베디드 리눅스 시스템을 통하여 두 프로세서 사이에서 공유 메모리 기능을 실험하였다. 듀얼 버스 구조에서 공유 메모리 구현을 위해 메모리 컨트롤러를 이용하였으며, 리스트 자료구조를 통하여 공유 메모리 세그먼트를 관리한다. AMP 멀티 코어 실험을 위하여 2개의 프로세서 코어에 리눅스 운영체제를 탑재하도록 하였다. 그리고 공유 메모리 테스트를 위하여 구현된 커널 모듈을 이용하여 공유 메모리 생성 및 이용이 가능함을 확인 하였다.
