对Cache基本原理不太清楚,可以先看我之前的Cache基本原理。 在《图解 | CPU-Cache》一文中介绍了VIVT、PIPT、VIPT三种查找方式。下面分析一下其歧义别名问题。 歧义:查找到的Cacheline先后指向多个物理地址。 别名:一个物理地址被加载到不同的Cacheline中。 VIVT 歧义:VIVT时,相同的虚拟地址映射不同的物理地址就...

In the world of computer science, cache plays a crucial role in the performance of microcomputers. Cache is a high-speed temporary storage location that stores frequently accessed data and instructions to reduce the time taken to access them from the main memory. The term "cache" is derived fr...

……这句话好生奇怪，明明是三大难题，为什么说是两个……计算机科学领域有两大难题：缓存失效、对象命名，以及误差边界。There
