4. 使用new和delete:参考帮助文件的Libraries and floating point support guide -> The ARM C and C++ libraries -> Stack pointer initialization and heap bounds 一般来说KEIL或厂家(如ST)提供的启动文件已包含该项支持;将汇编启动文件中的heap size项改改就好了。

SP:stack pointer栈指针,总是指向栈顶。 计算机中的堆栈主要用来保存临时数据、局部变量、存寄存器参数和中断/调用子程序程序的返回地址。 裸机中,SP 指向在系统启动文件中被设置为一个被预留大小的内存块顶部,每次调用函数,把需要的临时变化放入栈中,函数退出后,恢复为调用之前的值。
and PC values are in general-purpose registers, very efficient subroutine entry and exit sequences can be constructed with LDM and STM: • A single STM instruction at subroutine entry can push register contents and the return address onto the stack, updating the stack pointer in the process....
The region table also contains a function pointer that indicates what initialization is needed for the region, for example a copying, zeroing, or decompressing function. region表包含需要初始化的非根代码和数据区域的地址。 区域表还包含一个函数指针,指示区域需要初始化,例如复制,归零或解压缩功能。__...
