The CBOXes mediate the traffic from the L2 cache to the segmented L3 cache. Each
|
|
CBOX is responsible for one segment (2.5 MByte). The boxes maintain the coherence between all
|
|
CPU cores of the socket. Depending on the CPU core count, some CBOXes are not attached
|
|
to a 2.5 MByte slice but are still active and track the traffic.
