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...

The tag memory (66) is comprised of a virtual tag memory (68) and a physical tag memory (70). 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...
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...
