Abstract

Described embodiments provide a system having a bridge for connecting two different processor buses. The bridge receives a command from a first bus, the command having an identification field having a value. The command is then entered into a buffer in the bridge unless another command having the same identification field value exists in the buffer. Once the command with the same identification field value is removed from the buffer, the received command is entered into the buffer. Next, the buffered command is transmitted over a second bus. A response to the command is eventually received from the second bus, the response is transmitted over the first bus, and the command is then removed from the buffer. By not entering the received command until a similar command with the same identification value is removed from the buffer, command ordering is enforced even though multiple commands are pending in the buffer.
