Abstract
A communication controller transfers data cells and a control data cell representative of a target transmission rate from a system memory to a host; however, when a bus between the system memory and the communication controller is congested, the actual transmission rate for the data cells becomes smaller than the target transmission rate; a time stamp generator produces a time stamp representative of time for requesting a data transfer from the system memory, and a time stamp monitor compares the time stamp with actual stating time of transmission of the data cell to the host so as to check whether the target transmission rate is appropriate or not; if the target transmission rate is too large, the time stamp monitor requests a data processor to change the target transmission rate so that the data cells are transferred to the host at an appropriate transmission rate at all times.
