Processor 9500 Series Overview
The Intel
®
Itanium
®
Processor 9500 Series is an eight core architecture. It supports up
to eight cores, each with its own First Level Cache (FLC) and Mid Level Cache (MLC),
both of which are split into instruction and data caches (FLI/FLD and MLI/MLD,
respectively). The Last Level Cache (LLC) is shared among the cores and supports up to
32 MB. Also supported are the following page sizes for purges or inserts: 4K, 8K, 16K,
64K, 256K, 1M, 4M, 16M, 64M, 256M, 1G, 4G.
The architecture interfacing the cores to the system is referred to as the uncore. Each
Intel
®
Itanium
®
Processor 9500 Series core interfaces to the Ring. The Ring provides
connectivity to the Last Level Cache via the Cache Controllers (Cboxes). The Ring also
provides connectivity to Intel QPI via Ring/Sbox. The Sbox and Cbox provide the
supports for the two Intel QPI Caching Agents. The processor has two Home Agents
(Bbox). The Bbox interfaces between the memory controller and the Intel
®
QuickPath
Interconnect and supports a directory cache. Each memory controller supports two
Intel
®
Scalable Memory Interconnects (Intel
®
SMI) in lockstep. The Intel SMI are the
interconnects to Scalable Memory Buffer. The Intel
®
Itanium
®
Processor 9500 Series
processor supports six Intel
®
QuickPath Interconnects at the socket, four full width and
two half width. The Caching Agent, Home Agent, and Intel
®
QuickPath Interconnects
are connected via a 10-port Crossbar Router, each port supporting the Intel
®
QuickPath
Interconnect protocol.
