Abstract:
A serial stream interface for combining a master serial data stream comprising a sequence of N-bit master data packets and a slave serial data stream comprising a sequence of N-bit slave data packets, said serial stream interface comprising:a slave input interface comprising a slave buffer having a serial input for receiving said slave serial data stream and an N-bit slave parallel output for outputting each of said N-bit slave data packets, wherein said slave buffer stores said each N-bit slave data packet using at least one slave timing signal associated with said slave serial data stream; a source selection circuit having a first input channel capable of receiving an N-bit master parallel output from a first master data source and a second input channel coupled to said N-bit slave parallel output; and a serialization circuit having an input coupled to an output of said source selection circuit capable of receiving a selected one of said N-bit master parallel output and said N-bit slave parallel output and a serial output, wherein said serialization circuit sequentially shifts out each bit of said selected one of said N-bit master parallel output and said N-bit slave parallel output to produce an output serial data stream.
