Abstract

An integrated circuit chip, particularly a southbridge, is provided that has a first and a second circuit unit. Each circuit unit can send requests to the other one and send back a response when receiving a request that requires a response. The first circuit unit is connected to the second circuit unit to send to the second circuit unit request data relating to a request to be sent by the first circuit unit and response data relating to a response to be sent by the first circuit unit over a shared signal line.
