Product Description
PI7C7100 is the first triple port PCI-to-PCI Bridge device designed to be fully compliant with the 32-bit,
33MHz implementation of the
PCI Local Bus Specification, Revision 2.1
. PI7C7100 supports only
synchronous bus transactions between devices on the primary 33 MHz bus and the secondary buses
operating at 33 MHz. The primary and the secondary buses can also operate in concurrent mode,
resulting in added increase in system performance. Concurrent bus operation off-loads and isolates
unnecessary traffic from the primary bus; thereby enabling a master and a target device on the same
secondary PCI bus to communicate even while the primary bus is busy.
