2008年9月17日 · Stack: Stored in computer RAM just like the heap. Variables created on the stack will go out of scope and are automatically deallocated. Much faster to allocate in comparison to variables on the heap. Implemented with an actual stack data structure. Stores local data, return addresses, used for parameter passing.

2015年9月1日 · In modern architectures stack is mapped in ram. Programming languages such ar C, C++, Pascal can allocate memory in ram, this is called Heap allocation, and other variables which live withing functions are stack allocated. This dictated processors and operating systems to consider stack mapped within ram segment.

You cannot only use a stack, because a stack requires a last-in first-out allocation & deallocation order (i.e. you can only deallocate the newest allocated data; in a stack you cannot deallocate some old data and keep some newer one). Actually, …

2015年9月6日 · Heap and stack locations are at specific locations in virtual memory. The kernel then takes care of mapping memory locations between physical memory and virtual memory. Your program may have a chunk of memory allocated at 0x80000000, but that chunk of memory might be stored in location 0x49BA5400.

Generally speaking, the stack is preferred as it is usually in the CPU cache, so operations involving objects stored on it tend to be faster. However the stack is a limited resource, and shouldn't be used for anything large. Running out of stack memory is called a Stack buffer overflow. It's a serious thing to encounter, but you really shouldn ...

2017年1月2日 · Frames are added to the stack that may result in creating, editing or deleting data stored in heap space thereby changing a processes 'state'). So my question is, can all RAM usage be categorized either as being part of a heap or part of a stack? What else could be stored in RAM that doesn't fall into either of these categories?

2011年5月19日 · A stack usually contains local variables, passed parameters and control information for managing the stack itself. And, if you make a recursive call, you don't get a new stack, just a new stack frame. A frame is a chunk of the stack relevant to the current stack depth (whether that's by recursion or just regular function calls).

Ele passa ser tão transparente quanto a stack é em outras linguagens mais baixo nível (exceto Assembly). A alocação de ambos costuma ser realizada na RAM, mas nada impede que seja em outro local. A memória virtual pode colocar todo ou parte da stack ou do heap em memória de massa, por exemplo.

2024年10月3日 · You can place the stack anywhere in RAM. Often people place stack pointer at the end of RAM as it the most far position from other data which starts to be place from beginning of RAM. I often place SP to be at the beginning of RAM + stack size. When stack overflows it will invoke an exception which the code can handle.

2014年7月24日 · Heap and Stack selection is a vital and difficult task for STM32. You should think how much memory is required and then set your stack and heap to appropriate sizes. You also definately need to know where your variables or arrays are declared.
