AXI Axcache[1]与4K边界处理

dreamer21

在阅读AXI5spec时，看到了这样一段话

“A Non-modifiable transaction must not be split into multiple transactions or merged with other transactions.
...
A Non-modifiable transaction with burst length greater than 16 can be split into multiple transactions. Each resulting transaction must meet the requirements that are given in this subsection, except that:
• The burst length is reduced.
• The address of the generated bursts is adapted appropriately.”

产生了几个疑问：
1、Axcache[1]为0时一般什么时候做拆分？
2、如何理解这两种情况？
3、对于4K边界拆分处理，是否要考虑Axcache[1]?
