Abstract

본 발명은 공용램 억세스 제어방법 및 장치에 관한 것으로서, 이는 공용램을 담당하는 전용 프로그램 모듈과 타스크 버퍼를 사용하여 공용램에 보내고자 하는 데이타의 저장장소를 알려주어 공용램의 억세스 시간손실과 비효율성을 제거하도록 한 것이다.The present invention relates to a method and apparatus for controlling access to a common RAM, which uses a dedicated program module and a task buffer for a common RAM to inform a storage location of data to be sent to the common RAM to prevent access time loss and non-access of the common RAM. It is to remove efficiency.

이와 같은 본 발명은 공용램에 보내고자 하는 데이타가 저장되어 있는 영역에 대한 정보를 적어도 하나 이상의 프로그램 모듈로부터 순차 입력 받아 저장하는 단계와, 상기 저장된 각 프로그램 모듈의 정보들을 파악하여 첫번째 수순의 프로그램 모듈서부터 마지막 순서의 프로그램 모듈의 정보중에 어느 하나의 프로그램 모듈의 정보가 존재하면 그 정보에 해당하는 영역의 데이타를 공용램에 전달하여 주는 단계와, 상기 프로그램 모듈의 정보들을 파악한 결과 첫번째 프로그램 모듈서부터 마지막 프로그램 모듈의 정보가 존재하지 않으면 공용램의 억세스를 해제하는 단계로 이루어짐으로서, 달성된다.As described above, the present invention comprises sequentially receiving and storing information on an area in which data to be sent to a common RAM is stored from at least one program module, and grasping the information of each stored program module to obtain a first program module. If the information of any one of the program module information from the last sequence from the first to the last step of the step of delivering the data of the area corresponding to the information to the common RAM, and the information of the program module as a result of the first program module from the last If the information of the program module does not exist, it is achieved by the step of releasing access to the common RAM, it is achieved.

Claims

Receiving information about an area in which data to be sent to the common RAM is stored sequentially from at least one program module, and storing the information of each stored program module, and then storing the information of each program module from the first program module to the last program If the information of any one of the module information in the module information, the step of delivering the data of the area corresponding to the information to the common RAM, and as a result of grasping the information of the program module, information from the first program module to the last program module If not present, the method of controlling the access of a common RAM, characterized by comprising the step of releasing access to the common RAM.

A task buffer means for receiving and storing information on an area in which data to be sent to at least one program module from the at least one program module is stored, and information of each program module stored in the task buffer means, and the program module of the first procedure Dedicated program module for transmitting data to common RAM by accessing the corresponding area of memory means as the information if the information of any one of the program module information from the last sequence from the program module, and the control generated by the dedicated program module A common RAM access control device including control logic means for accessing a common RAM according to information.

The apparatus of claim 2, wherein the task buffer comprises a task head for storing information of each program module and a task tile for storing the number of information of each program module.
