PAD复用、仲裁等等都是因为多个输出需求只对应一个实际输出端口,这个时候选择哪个请求也是有讲究的。 在系统层面上,虚拟地址产生的原因之一也是因为软件应用的地址空间远大于实际物理空间。这个时候系统上的硬件或者软件除了需要完成业务,还要进行VA到PA的转换,让业务访问到实际的物理地址空间。 虚拟地址产生的另外一个原...

系统层面，虚拟地址的产生原因之一是软件应用地址空间的膨胀，远远超出了实际物理空间。此时，硬件或软件不仅要完成业务，还需承担VA到PA的转换任务，确保业务能访问到真实的物理地址空间。虚拟地址的另一层意义，在于为软件减负，让开发者无需关心变量的物理存储位置，避免地址冲突的困扰。为实现这一转换，硬...

I have a question about EIP register. I know it's address of newt instruction, but it means physical address or virtual address? Also, if I have a parallel program, are EIP values of one instruction are same among different processes? Thanks. Translate...
byte-sized cells. Each byte has a unique physical address (PA). The first byte has an address of 0, the next byte an address of 1, the next byte an address of 2, and so on. Given this simple organization, the most natural way for a CPU to ...
Manage your virtual address and virtual mailbox from anywhere. Clients can view & manage their postal mail and mailing address using a computer, tablet or smartphone. Create a Business or Personal account.
The physical and virtual tag memories are both addressable by the least significant bits (LSB) of the address signal to output tag portions of addresses associated with data stored in the cache data memory (64). A switch (78) selects between the outputs from the memories (68) and (70) ...
StorPortGetVirtualAddress 返回与 PhysicalAddress 参数中指示的物理地址关联的虚拟地址。 通常,此物理地址是通过调用 StorPortGetPhysicalAddress获得的。言论物理地址必须是通过调用 StorPortGetPhysicalAddress获取的地址。StorPortGetVirtualAddress 使用STOR_PHYSICAL_ADDRESS 来表示物理地址。
