Abstract
In one aspect, a method of transferring data over a plurality of communication lines is described. A first command is sent from a master device coupled with the communication lines to a first destination slave device coupled with the communication lines instructing the first destination slave device to listen to and write data from the communication lines starting at a first time. A second command is sent from the master device to a second source slave device coupled with the communication lines instructing the second source slave device to read and output first data onto the communication lines starting at or after the first time. In this way, the first data output from the second source slave device beginning at the first time is stored by the first destination slave device beginning at the first time without requiring first transferring the data to the master device or any other device.
