Apparatus and method for data processing having an on-chip or off-chip interconnect between two or more devices

摘要

A data processing apparatus 2 is provided with multiple devices 4, 6, 8, 10. These devices generate parallel signals using a parallel signal protocol. A serialising circuit 26, 28, 30, 32, 34 captures a set of parallel signals, serialises them to form a serial stream of data and transmits this serial stream of data. A deserialising circuit 44, 46, 36, 38, 40, 42, 30, 26 at a destination device receives this serial stream of data, deserialises this serial stream of data to form a second set of parallel signals corresponding to the first set of parallel signals and then applies this second set of parallel signals to the destination device.
