The GeodeLink™ PCI Bus South Bridge (GLPCI_SB) pro-
vides a PCI interface for GeodeLink Device based designs.
Its three major functions are:
1)
2)
3)
Features include:
• PCI v2.2 compliance. Optional signals PERR#, SERR#,
• 32-bit, 66 MHz PCI bus operation and 64-bit, 66 MHz
• Target support for fast back-to-back transactions.
• Zero wait state operation within a PCI burst.
• MSR access mailbox in PCI configuration space.
• Capable of handling in-bound transactions after
• Dynamic clock stop/start support for GeodeLink and PCI

• Programmable IDSEL selection.
• Support active decoding for Legacy I/O space 000h to
• Support subtractive decode for memory and I/O space.
• Special performance enhancements for fast IDE PIO
The GLPCI_SB module is composed of the following major
blocks:
• GeodeLink Interface
• FIFO/Synchronization
• Transaction Forwarding
• PCI Bus Interface
• CPU Interface Serial (CIS)
The GLIU and PCI bus interfaces provide adaptation to the
respective buses. The Transaction Forwarding block pro-
vides bridging logic. The CIS block provides serial output to
the CPU for any change in SSMI and the selected side-
band signals. Little endian byte ordering is used on all sig-
nal buses.
