Abstract
A PCI bridge circuit connects to first and second PCI buses and performs data transfer between PCI devices. The PCI bridge circuit has a data buffer and controller and the controller, prior to the establishment of a data transfer state with the first PCI device via the first PCI bus, receives data from the second PCI device via the second PCI bus into a data buffer and inserts a wait state. Consequently while reducing the capacity of the data buffer, data transfer between PCI devices can be performed without affecting the transfer performance.
