>Other high performance MPU related presentations at Hot Chips included one on the
>Blackford chipset, the Tulsa MPU, and the Core microarchitecture. The latter was
>mostly a rehash of IDF news, but did include some new details (but not enough to merit a new article).
The interesting new Core 2 tidbits were (IMO)...
- 36 mm^2 and 19 million transistors per core
- L1d has 8 banks and dual-ported tags
- 8 line fill/write combining buffers
- 4 write back buffers
- MOB = 32x loads plus 20x stores
- 32-entry 4-way PDC
- 16-entry 4-way L0 dTLB for small pages
- 16-entry 4-way L0 dTLB for large pages
- 256-entry 4-way L1 dTLB for small pages
- 32-entry 4-way L1 dTLB for large pages
- mention of IP-based prefetcher
(see Intel #314175 for details)
YMMV. :)
