Abstract

A command storage technique that fulfils ordering rules is provided. This technique may be used in HyperTransport compliant southbridge devices. A command transmit engine comprises a command storage unit that is adapted to receive incoming commands of different command types and store the command in the order in which the commands were received. The command transmit engine further comprises an ordering rule controller that is connected to the command storage unit to select stored commands to be transmitted. The ordering rule controller is adapted to perform the selection according to predefined command ordering rules. The command ordering rules are command type dependent.
