TIGHTLY-COUPLED MEMORY MANAGEMENT METHOD TO IMPROVE RESPONSIBILITY OF REAL-TIME PROCESSES

摘要

PURPOSE: A tightly-coupled memory management method is provided to improve the response of real-time processes by determining the page to be loaded on the TCM in consideration of a process priority or memory address accessed to TCM, access frequency and recent access time. CONSTITUTION: A process to be saved in a tightly-coupled memory (TCM) requests the access to TCM(210). The TCM transfers the process or the memory information to a TCM manager(220). The process information includes the priority information. The memory information includes the address of the accessed memory, access frequency and recent access time. The TCM manager determines a memory page to be loaded on TCM in consideration of the information on the process or the memory, and then executes the load(230).
