Introduction
Maximum theoretical bandwidth on the interface of 8 GB/s in each direction
simultaneously, for an aggregate of 16 GB/s when x16 Gen 2
Hierarchical PCI-compliant configuration mechanism for downstream devices
Traditional PCI style traffic (asynchronous snooped, PCI ordering)
PCI Express* extended configuration space. The first 256 bytes of configuration
space aliases directly to the PCI Compatibility configuration space. The remaining
portion of the fixed 4-KB block of memory-mapped space above that (starting at
100h) is known as extended configuration space.
portion of the fixed 4-KB block of memory-mapped space above that (starting at
100h) is known as extended configuration space.
PCI Express* Enhanced Access Mechanism; accessing the device configuration
space in a flat memory mapped fashion
Automatic discovery, negotiation, and training of link out of reset
Traditional AGP style traffic (asynchronous non-snooped, PCI-X Relaxed ordering)
Peer segment destination posted write traffic (no peer-to-peer read traffic) in
Virtual Channel 0
DMI -> PCI Express* Port 0
64-bit downstream address format, but the processor never generates an address
above 64 GB (Bits 63:36 will always be zeros)
64-bit upstream address format, but the processor responds to upstream read
transactions to addresses above 64 GB (addresses where any of Bits 63:36 are
nonzero) with an Unsupported Request response. Upstream write transactions to
addresses above 64 GB will be dropped.
nonzero) with an Unsupported Request response. Upstream write transactions to
addresses above 64 GB will be dropped.
Re-issues Configuration cycles that have been previously completed with the
Configuration Retry status
PCI Express* reference clock is 100-MHz differential clock
Power Management Event (PME) functions
Dynamic width capability
Message Signaled Interrupt (MSI and MSI-X) messages
Polarity inversion
Note:
The processor does not support PCI Express* Hot-Plug.
