METHOD AND CACHE SYSTEM FOR STORING FILE'S DATA IN MEMORY BLOCK WHICH DIVIDES CACHE MEMORY

摘要

A cache method for storing file data by dividing a cache memory into memory blocks and a cache system thereof are provided to offer the efficient large size cache system in a system permitting random access to multiple files and receiving concurrent access requests, and efficiently index data based on location information of the file to prevent memory update/access of each block from affecting other blocks. A cache storing part(140) stores data read from the file to each memory block. A block allocator(220) allocates the memory blocks of the cache storing part to store the data. A cache manager(130) transmits the first data stored in the searched memory block to an application(150) by searching the memory block storing the first data of the first file requested from the application in the cache storing part. The memory block storing the first data stores the file data by dividing the cache memory into the memory blocks including reference information including the number of applications which request the first data and not complete transmission of the first data.
