Il est dit : "The L2 cache on the PA6T-1682M is 2MB shared among two PA6T PPC cores. The really interesting bit is that the cores are not connected to the cache itself but to the CONEXIUM crossbar. This means it is addressed in a serial fashion, but can also be used as a cache by other parts of the system. It can be an I/O or DMA cache as well as a CPU cache, but each unit needs to wait it's turn. Luckily, interconnect it is on is up to the job, and the cache can pass up to 1G addresses per second, and it is pipelined so it can have multiple things in flight at once. It also can send and receive data in parallel."
Je crois d'ailleurs que le partage de ce cache L2 (au-delà des coeurs) est l'une des particularité du PA6T.
Pour les infos internes, on en a quand même sur les caches, le pipeline, etc. Il y a apparemment 6 unités d'exécution (2 pour les entiers, 1 FP, 1 pour "AltiVec", ...)
