PCI-PCI bridge and PCI-bus audio accelerator integrated circuit

摘要

A semiconductor device with an embedded PCI 2.1 compliant bridge provides expanded functionality as system-level implementations of a PCI- to-PCI bridge, and enhances the level of integration possible. The embedded PCI-to-PCI bridge allows the creation of multi-function, multimedia add-on cards supporting multiple devices. Multi-function, multimedia subsystems that provide audio, graphics, MPEG, etc., are mapped into a bridged-to PCI-bus that keeps such traffic off the main PCI- bus. The advantage for the system or add-in card vendor is that the various multimedia chips that are combined can come from different sources, providing an optimized and highly customized combination of functions.
