Tài liệu the PCI Bus demystified phần 7

In this chapter we’re primarily concerned with the PCI-to-PCI
(P2P) bridge, that is, a bridge that connects two PCI bus segments.
The P2P bridge is defined in PCI-to-PCI Bridge Architecture Specification,
Rev. 1.1, December 1998. But before delving into the details
of the P2P bridge, we should note briefly that there are two other
types of bridges that serve specific roles as illustrated in Figure 8-1.
