Title (EN) ELECTRONIC DEVICE AND CONTROL METHOD THEREOF
(FR) DISPOSITIF ÉLECTRONIQUE ET SON PROCÉDÉ DE COMMANDE
(KO) 전자 장치 및 그의 제어 방법
Abstract:
(EN) Disclosed are an electronic device and a control method thereof. The electronic device according to the present disclosure includes a memory, a cache memory, a CPU, and includes a processor which controls the electronic device by using a program stored in the memory, wherein the CPU monitors an input address at which an input value is accessed in the cache memory, and changes the input address when the input address at which the input value is accessed in the cache memory is changed to a preset pattern.
(FR) La présente invention porte sur un dispositif électronique et sur son procédé de commande. Le dispositif électronique selon la présente invention comprend une mémoire, une mémoire cache, une CPU, ainsi qu'un processeur qui commande le dispositif électronique à l'aide d'un programme stocké dans la mémoire. La CPU surveille une adresse d'entrée au niveau de laquelle il est possible d'accéder à une valeur d'entrée dans la mémoire cache, et change l'adresse d'entrée, lorsque l'adresse d'entrée au niveau de laquelle il est possible d'accéder à la valeur d'entrée dans la mémoire cache est modifiée, en un modèle prédéfini.
(KO) 전자 장치 및 그의 제어 방법이 개시된다. 본 개시에 따른 전자 장치는, 메모리 및 캐시 메모리 및 CPU를 포함하며, 메모리에 저장된 프로그램을 이용하여 전자 장치를 제어하는 프로세서를 포함하며, CPU는, 캐시 메모리에 입력값이 액세스되는 입력 주소를 모니터링하며, 캐시 메모리에 입력값이 액세스되는 입력 주소가 기 설정된 패턴으로 변경되는 경우, 입력 주소를 변경하는 것을 특징으로 한다.
