The 82375EB/SB PCI-EISA Bridge (PCEB) provides the master/slave functions on both the PCI Local Bus
and the EISA Bus. Functioning as a bridge between the PCI and EISA buses, the PCEB provides the address
and data paths, bus controls, and bus protocol translation for PCI-to-EISA and EISA-to-PCI transfers. Exten-
sive data buffering in both directions increases system performance by maximizing PCI and EISA Bus efficien-
cy and allowing concurrency on the two buses. The PCEB’s buffer management mechanism ensures data
coherency. The PCEB integrates central bus control functions including a programmable bus arbiter for the
PCI Bus and EISA data swap buffers for the EISA Bus. Integrated system functions include PCI parity genera-
tion, system error reporting, and programmable PCI and EISA memory and I/O address space mapping and
decoding. The PCEB also contains a BIOS Timer that can be used to implement timing loops. The PCEB is
intended to be used with the EISA System Component (ESC) to provide an EISA I/O subsystem interface.
This document describes both the 82375EB and 82375SB components. Unshaded areas describe the
82375EB. Shaded areas, like this one, describe the 82375SB operations that differ from the 82375EB.
