For each running process, the mapping between virtual and physical address is maintained in a data structure called the page table.

对于每个正在运行的进程，虚拟地址与物理地址之间的映射是在一个称作页表的数据结构中维护的。

youdao

It has an integrated memory management unit that is normally used to provide access to the address space of one process by using the same page table lookup as the PPE.

它具有一个集成的内存管理单元，通常使用与PPE类似的页表查询机制来提供对某个进程地址空间的访问。

youdao

For every page mapped by each process, page-table entries must also be created to map the virtual address to the physical address.

由于每个页都要由每个进程映射，必须创建页表条目来将虚拟地址映射到物理地址。
