handle low memory conditions. The first level Configurator performs the actual memory configuration, deallocation, and reconfiguration operations with C functions such as malloc (), free (), realloc ().SGI STL Second Level configuratorTemplateClass __default_alloc_template {...};Comments:1. Maintain 16 free lists, responsible for the sub-configuration capability of 16 small blocks.

, there is no change from the logical address to the linear address. From paragraph to page, each user process has a single page catalog table (PDT), which is stored in the CR3 at run time. CR3 (page catalog) + Top 10 => Page Table base + 10-bit => Page table entry + 12-bit => physical page address How 3g-4g and Mem_map are mapped:Divided into three types: low memory/normal memory/high-end memory.Low-end

What are the strategies for memory allocation?We start with the principle of compiling, different development environment, development language will have different strategies.

large, which will occupy a lot of memory during array initialization, in this way, compilation may sometimes fail. yesterday there were several crashes and only 64 × 64 arrays were used. Later, we put array initialization out of main and use it as a global variable to statically allocate a piece of memory space in the stack. Although feasible, it also occupies a lot of
