Abstract: An asynchronous bridge with command prefetching, including a command prefetcher as well as a command receiver. The command receiver receives a first command from a first-clock computing device. The first command is issued to operate a second-clock computing device. The command prefetcher prefetches a second command from the first-clock computing device before the first-clock computing device receives notice of execution completion of the first command. In this manner, when the command receiver receives the second command (that the first-clock computing device formally issues to operate the second-clock computing device), the second-clock computing device already operates in response to the prefetched second command.
