1. 寄存器( register),是最快的存储区,位于处理器内部。因为寄存器的数量极其有限,所以寄存器由编译器根据需求进行分配。程序员无法使用Java代码使用寄存器中的存储空间,或者说:在Java开发的层面上,寄存器的操作已经被封装。 2. 栈( stack),位于通用 RAM。存取速度快,仅次于寄存器。栈指针若向下移动,则分配新的内存;...
After analysis on the memory allocation behavior of Java programs, it is concluded that almost 90% of the allocations are of small sizes. If simple hardware can be designed to do memory allocations of small block sizes, the performance in Java program execution will be greatly improved.Richard ...

Memory allocation The code heap containing non-method code is used for JVM internal code and consists of a 3 MB fixed memory block. The rest of the code cache memory is equally allocated for the profiled code and non-profiled code segments. You have control of this via command line comman...

Stack memory size is very less when compared to Heap memory. Because of simplicity in memory allocation (LIFO), stack memory is very fast when compared to heap memory. That’s all forJava Heap Space vs Stack Memoryin terms of java application, I hope it will clear your doubts regarding me...

The mcheck() function is called automatically before the first memory allocation takes place—useful in those cases when some dynamic blocks are allocated before entering main(). 在第一内存分配发生前,mcheck()函数被自动调用--当在进入main()之前,动态内存块被分配的情况下,非常有用。
