Abstract
Methods and systems are described for emulating a bi-directional synchronous communications protocol for bi-directional bus communication using unidirectional channels between a master device and a slave device. The master device includes a physical interface to the unidirectional channels that resynchronizes outgoing and incoming data streams in order to reconstruct a bitstream that is compliant with the bi-directional synchronous communications protocol. The reconstructed bitstream is input to the master digital interface controller as though it had been received from the slave device.
