你好,想问一下,咱们目前昆明湖的设计中,总线协议是片内采用TileLink,片外采用CHI协议吗,之前说昆明湖准备替换TileLink为CHI,目前看到TL转CHI的bridge开发,这样的话,核间核内是保留了Tilelink协议然后通过Bridge,外设总线采用CHI的方案吗?

您好,我发现在L1Cache中请求NtoB,很多情况下L2cache的D通道会自动升权到toT响应,在Dcache中应该是没问题的,但是在多核ICache情况在,ICache正常情况下应该只读,但是T权限是可读可写,那按我的理解多核情况下icache频繁的probe toB,那这样性能上是不是会有问题呢?请问当时设计的promoteT是基于哪些方面的考虑呢?谢谢!
