在Intel的文档“Intel 64 and IA-32 Architectures Software Developer's Manual Volume 3A System Programming Guide”，在“Memory Cache Control”章里，说有的Cache是“fully associative”有的Cache是“fully set associative ”两者有区别吗？

在Intel的文档里有“set associative”“fully set associative”和“fully associative”，比如：
1。 Instruction TLB (Large Pages)
P6 family processors: 2 entries, fully associative.
2。 Data TLB (Large Pages)
Pentium 4 and Intel Xeon processors: 64 entries, fully set associative; shared with small page data TLBs.
3。 L2 Unified Cache
Intel Core 2 Duo processor: up to 4-MByte, 16-way set associative, 64-byte cache line size.
请注意，这里面有的是“fully set associative”有的是“set associative”，所以我的理解这些概念是有区别的。

fully set associative”和“fully associative没区别。都是指全相联。全相联可看作只有一个组的组相联，所谓fully set就是指这个意思吧。
