Working Principles

The PCI6420GHK acts as a bridge between the PCI bus and peripheral devices by translating and routing data between the two. It utilizes a combination of hardware and software techniques to ensure efficient and reliable communication.

When a peripheral device initiates a data transfer, it sends a request signal (REQ#) to the PCI6420GHK. The IC then processes the request, checks for any errors, and forwards the data to the appropriate destination. Similarly, when the PCI bus needs to send data to a peripheral device, the IC handles the data transfer by coordinating the necessary signals and protocols.
