PROBLEM TO BE SOLVED: To provide a memory management system, preventing an increase in a hardware scale and efficiently managing the consistency of a cache memory and a shared memory in processing an image in a multi-processor system having a plurality of processors, the cache memory and the shared memory. SOLUTION: This memory management system includes: the plurality of processors 101-105; and the shared memory 131 accessed from the plurality of processors 101-105, wherein each of the plurality of processors includes the cache memories 111-115 capable of instructing for cancelling and writing back a specified area from a program, and the program operated on each processor cancels an input data area of the cache memory according to a cancel instruction immediately before executing the program as a processing unit, and writes back an output data area of the cache memory to the shared memory immediately after executing the program as a processing unit according to a write-back instruction.
