例如，一个ppe端的邮箱寄存器会作为一个只写的物理内存位置出现。
When a program tries to access memory using a virtual address, the OS in combination with on-chip hardware maps that virtual address to the physical location.
当程序尝试使用虚拟地址访问内存时，操作系统结合片上硬件将该虚拟地址映射到物理位置。
Every time a memory location is addressed for program instructions or data, a virtual address is translated into a physical or real memory address.
每次为程序指令或数据处理内存位置时，都需要将虚拟地址转换成物理(或实际)内存地址。
The MSI memory location is a physical bus address, so it must be translated to virtual address space both on device and host.
MSI的内存位置的物理地址，所以它必须转换为对设备和主机的虚拟地址空间。
The MSI memory location is a physical bus address, so it must be translated to virtual address space both on device and host.
