Abstract: If it is determined in step S51 that allocation for an instruction part has been requested and it is determined in step S52 that a memory use amount of an instruction part of an allocation target program exceeds an upper limit, a memory area that is being used by the instruction part of the allocation target program is released in step S53 and memory allocation for the instruction part is performed in step S54. If it is determined in step S52 that the memory use amount of the instruction part of the allocation target program does not exceed the upper limit, the process in step S53 is skipped. If it is determined in step S51 that allocation for a data part is requested, a normal memory allocation process is performed in step S55. The present disclosure may be applied to, for example, an embedded device.

Abstract: A memory manager secures memory areas according to requests from programs and sets ranks designated by the programs to the secured memory areas. The memory manager selects a memory area released on the basis of the rank of each memory area, from the secured memory areas, when an available capacity of a main storage device is insufficient. The memory manager releases the selected memory area and secures a new memory area. The present disclosure can be applied to an embedded apparatus.

Abstract: Provided is a memory management apparatus including a determiner configured to determine whether or not a pattern of writing data being data to be a target of an instruction of writing in a memory is a frequently-appearing pattern, and a setting unit configured to set a shared reference with respect to the writing data having the frequently-appearing pattern in a case where it is determined by the determiner that the pattern of the writing data is the frequently-appearing pattern and data of the frequently-appearing pattern has already been held in the memory.
