问题描述
英特尔酷睿i7具有每核L1和L2缓存,以及大型共享的L3缓存。我需要知道哪种互连将多个L2连接到单个L3。我是一名学生,需要编写缓存子系统的粗略行为模型。
它是横线吗?一辆公共汽车?戒指?我遇到的参考文献都提到了缓存的结构细节,但是都没有提及存在哪种片上互连。
The Intel core i7 has per-core L1 and L2 caches, and a large shared L3 cache. I need to know what kind of an interconnect connects the multiple L2s to the single L3. I am a student, and need to write a rough behavioral model of the cache subsystem.Is it a crossbar? A single bus? a ring? The references I came across mention structural details of the caches, but none of them mention what kind of on-chip interconnect exists.
谢谢,

推荐答案
现代i7使用环。从:
您的模型将非常粗糙,但是您可以从有关L3的i7性能计数器的公共信息中收集更多信息。
Your model will be very rough, but you may be able to glean more information from public information on i7 performance counters pertaining to the L3.
