Memory management is the process of recognizing when allocated objects are no longer needed, deallocating (freeing) the memory used by such objects, and making it available for subsequent allocations. In some programming languages, memory management is the programmer’s responsibility. The complexity of that task

•Another way to allocate memory, where the memory will remain allocated until you manually de-allocate it •Returns a pointer to the newly allocated memory •Terminology note: –If using int x; the allocation occurs on a region of memory called the stack –If using new int; the allocation occurs on a region of memory called the heap

Memory-Management Unit (MMU) • Hardware device that maps logical/virtual to physical address. • In MMU the value in the relocation register is added to every address generated by a program at the time the address is sent to memory. • The program deals with logical addresses; it

A virtual memory system consists of software (in the operating system) and memory mapping hardware. The needed hardware may be implemented as a separate IC chip, a memory management unit (MMU). 11 Uses for Memory Mapping Relocation. A MMU makes it possible for all processes in memory to start at the same address. Artificially contiguous addresses.

8: Memory Management 4 MEMORY MANAGEMENT • The concept of a logical address space that is bound to a separate physical address space is central to proper memory management. • Logical address – generated by the CPU; also referred to as virtual address • Physical address – address seen by the memory unit • Logical and physical addresses are the same in compile-time and load-
