MemorySegmentationPageSizeProgramBehaviourLocalityOn the basis of empirical data two topics concerning virtual memory systems are discussed: determining an optimal page size and performance of segmentation as compared to paging. Several production programs have been executed (on a simulator) both in a ...

分段错误 意味着程序试图访问无效或非法的内存地址,例如0或大于任何有效指针的值。 页错误 是当指针尝试访问当前未映射到物理内存的地址空间页面时发生的,因此 MMU 需要从磁盘中获取该页面才能使用。前者是非法状态,程序通常会被中止; 后者是完全正常的,程序甚至不会知道它存在。 “Segementation”与早期x86处理器使用...

memory-mapping a file. We can’t start the region at28 KiBbecause it would collide with the already mapped page at1004 KiB. So we have to look further until we find a large enough unmapped area, for example at1008 KiB. This is a similar fragmentation problem as withsegmentation....
