Title (EN) CACHE CONTROL DEVICE FOR PREFETCHING AND PREFETCHING METHOD USING CACHE CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE DE CACHE POUR PRÉLECTURE ET PROCÉDÉ DE PRÉLECTURE À L'AIDE DU DISPOSITIF DE COMMANDE DE CACHE
(KO) 프리페치를 위한 캐시 제어 장치 및 그 캐시 제어 장치를 이용한 프리페치 방법
Abstract: front page image
(EN)The present invention relates to prefetching, and to a cache control device for prefetching and a prefetching method using the cache control device, wherein the catch control device analyzes a memory access pattern of a program code, inserts, into the program code, a prefetching command generated by encoding the analyzed access pattern, and executes the prefetching command inserted into the program code so as to prefetch data into a cache, thereby maximizing prefetching efficiency.
(FR)La présente invention concerne la prélecture, et un dispositif de commande de cache pour prélecture et un procédé de prélecture à l'aide du dispositif de commande de cache, le dispositif de commande de cache analysant un motif d'accès mémoire d'un code de programme, insérant, dans le code de programme, une instruction de prélecture générée par codage du motif d'accès analysé, et exécutant l'instruction de prélecture insérée dans le code de programme afin d'envoyer dans un cache des données de prélecture, ce qui permet de maximiser l'efficacité de prélecture.
(KO)본 발명은 프리페치에 관한 것으로 프로그램 코드의 메모리 접근 패턴을 분석하고, 접근 패턴을 분석을 인코딩하여 생성된 프리페치 명령어를 프로그램 코드에 삽입하여, 프로그램 코드에 삽입된 프리페치 명령어가 실행되면, 캐시에 데이터를 미리 인출하는 프리페치를 위한 캐시 제어 장치 및 그 캐시 제어 장치를 이용한 프리페치 방법을 제공함으로써, 프리페치 효율을 최대화한다.
