  2. Stack-based memory allocation - Wikipedia

    en.wikipedia.org/wiki/Stack-based_memory_allocation

    The stack is often used to store variables of fixed length local to the currently active functions. Programmers may further choose to explicitly use the stack to store local data of variable length. If a region of memory lies on the thread's stack, that memory is said to have been allocated on the stack, i.e. stack-based memory allocation (SBMA).

  3. Data segment - Wikipedia

    en.wikipedia.org/wiki/Data_segment

    The stack segment traditionally adjoined the heap segment and they grew towards each other; when the stack pointer met the heap pointer, free memory was exhausted. With large address spaces and virtual memory techniques they tend to be placed more freely, but they still typically grow in a converging direction.

  4. Code segment - Wikipedia

    en.wikipedia.org/wiki/Code_segment

    This shows the typical layout of a simple computer's program memory with the text, various data, and stack and heap sections. In computing, a code segment, also known as a text segment or simply as text, is a portion of an object file or the corresponding section of the program's virtual address space that contains executable instructions.

  5. x86 memory segmentation - Wikipedia

    en.wikipedia.org/wiki/X86_memory_segmentation

    The memory model concept derives from the setup of the segment registers. For example, in the tiny model CS=DS=SS, that is the program's code, data, and stack are all contained within a single 64 KB segment. In the small memory model DS=SS, so both data and stack reside in the same segment; CS points to a different code segment of up to 64 KB.

  6. Stack trace - Wikipedia

    en.wikipedia.org/wiki/Stack_trace

    In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap .

  7. Region-based memory management - Wikipedia

    en.wikipedia.org/wiki/Region-based_memory_management

    Like stack allocation, regions facilitate allocation and deallocation of memory with low overhead; but they are more flexible, allowing objects to live longer than the stack frame in which they were allocated. In typical implementations, all objects in a region are allocated in a single contiguous range of memory addresses, similarly to how ...

  8. C dynamic memory allocation - Wikipedia

    en.wikipedia.org/wiki/C_dynamic_memory_allocation

    dlmalloc is a boundary tag allocator. Memory on the heap is allocated as "chunks", an 8-byte aligned data structure which contains a header, and usable memory. Allocated memory contains an 8- or 16-byte overhead for the size of the chunk and usage flags (similar to a dope vector). Unallocated chunks also store pointers to other free chunks in ...

  9. Memory footprint - Wikipedia

    en.wikipedia.org/wiki/Memory_footprint

    This includes all sorts of active memory regions like code segment containing (mostly) program instructions (and occasionally constants), data segment (both initialized and uninitialized), [1] heap memory, call stack, plus memory required to hold any additional data structures, such as symbol tables, debugging data structures, open files ...
