21150 PCI-to-PCI Bridge
The 21150 is a 32/32-bit 33MHz PCI-to-PCI bridge that allows the board to support up to
seven loads on its secondary PCI bus through a passive backplane. The bridge is fully
compliant the PCI Local Bus Specification, Rev. 2.1. It provides full support for delayed
transactions, which enables the buffering of memory read, I/O and configuration
transactions. The 21150 have separate posted write, read data and delayed transaction
queues with a high buffering capability.
In addition, it supports buffering of simultaneous multiple posted writes and delayed
transactions in both directions.
The PCI-to-PCI bridge allows the Primary and Secondary 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.
n
82371AB PCI-to-ISA Bridge / IDE Xcelerator (PIIX4)
The PCI-to-ISA bridge is configured to support signals to directly drive IDE interfaces,
USB ports, extra communication ports (Serial Ports 3 and 4), and standard Serial Ports (1
and 2), floppy disk drives, mouse and keyboard through a super I/O controller
(FDC37C672).
