Method of managing memory in multiprocessor system on chip

A method of managing memory in a multiprocessor system on chip (MPSoC) having two or more layered memory structure, the method comprising:

• referring to (reading or checking) a predetermined symbol table and determining a storage location of a variable or a function based on a memory access frequency of a symbol;
• comparing the determined storage location and a previous storage location in which the variable or the function was lastly stored, and determining whether the determined storage location is different from the previous storage location;
• and
• copying the variable or the function stored in the previous storage location to the determined storage location if the determined storage location is different from the previous storage location.

A method of managing memory in a multiprocessor system on chip (MPSoC), the method comprising:

• determining whether a memory region used exclusively for the bottom of a predetermined function exists and determining whether the exclusive memory region can be allocated to a first memory;
• if it is determined that the exclusive memory region cannot be allocated to the first memory, comparing a performance gain of a case a predetermined size of a memory region allocated to a second memory is stored in the first memory and a cost for copying and restoring the size of a memory region of the first memory to the second memory;
• and
• if the performance gain is greater than the cost, copying the size of the memory region to the second memory and allocating the size of the memory region to the first memory.
