解析 一种是逻辑地址( Logical Address):允许在程序中编排的地址。一种是物理地址( Physical Address):信息在存健器 中实际存故的地址。 一种是逻辑地址( Logical Address):允许在程序中编排的地址。一种是物理地址( Physical Address):信息在存健器 中实际存故的地址。
由此个人认为PPHYSICAL_ADDRESS LogicalAddress 这种定义只是微软命名习惯上的差异,这里的LogicalAddress就是物理地址而并非传统意义上的逻辑地址。
第三个参数有点不是很能理解,PPHYSICAL_ADDRESS LogicalAddress,至少从定义的变量名上看,微软似乎在暗示我:逻辑地址和物理地址是相同的这样一个事实。 虚拟地址到物理地址的转化方法是与体系结构相关的。有分段、分页两种方式。x86 cpu下分段分页都是支持的。MMU负责从虚拟地址到物理地址的转化。逻辑地址是段标识+段...
DMA操作前需要分配物理地址连续的一个Buffer,AllocateCommonBuffer函数提供了这个功能,该函数原型如下: PVOID AllocateCommonBuffer( _In_ PDMA_ADAPTER DmaAdapter, _In_ ULONG Length, _Out_ PPHYSICAL_ADDRESS LogicalAddress, _In_ BOOLEAN CacheEnabled ); 第三个参数有点不是很能理解,PPHYSICAL_ADDRESS Logical...
be expressed as [A code identifier: 0x08111111], so, to complete some" Linear address (linear address), or virtual address (virtual, address) With similar logical address, it is not a real address, if the logical address is the hardware platform segment management ...
address associated with each data write operation to a block, where the block has a plurality of pages, (C) writing the physical-to-logical address map to a last of the plurality of pages during a write to a second to last page of the block and (D) initiating a recycle operation of ...
Linear Adress,created by adding logical address to the base of segment, CS,DS,ES,SS,FSor GS. When Paging is enabled, the page tables are used to translate linear address to physical address. On the Other Hand, Physical Address is nothing but, the address value that appears on pins of pr...
For instance, the domain name example.com might translate to the physical address 198.102.434.8. 例如,域名 example.com 可以转换为物理地址 198.102.434.8。 support.google Distributed logical address and physical address conversion method, apparatus and device 一种分布式逻辑地址与物理地址互换方法、装...
The library assigns each tape drive a unique address to indicate its physical and logical location. The library assigns each tape drive a unique address to indicate its physical location, which is shown in Figure 1. The physical numbering is bottom up on all drives. This information is shown ...
