Tsi350

PCI-to-PCI Bridge

The Tundra Semiconductor Tsi350 is a PCI-to-PCI bridge that is fully

compliant with PCI Local Bus Specification, Revision 2.3. The Tsi350 has

sufficient clock and arbitration pins to support nine PCI bus master devices

directly on its secondary interface.

The Tsi350 allows the two PCI buses to operate concurrently. This means that

a master and a target on the same PCI bus can communicate while the other

PCI bus is busy. This traffic isolation may increase system performance in

applications such as multimedia.

The Tsi350 makes it possible to extend a system’s load capability limit beyond

that of a single PCI bus by allowing motherboard designers to add more PCI

devices or more PCI option card slots than a single PCI bus can support.

The Tsi350 has two identical PCI Interfaces that each handle PCI transactions

for its respective bus, and, depending on the type of transaction, can act as

either a bus master or a bus slave. These interfaces transfer data and control

information flowing to and from the blocks shown below.
