Latest Patents

One of his latest patents is titled "Bi-directional serializer/deserializer with discretionary loop-back." This invention discloses a serializer/deserializer pair that features a discretionary loop-back mechanism. This mechanism enables a redundant high-bandwidth node architecture, benefiting from the clever re-use of two identical integrated circuits. The first integrated circuit functions as an add/drop multiplexor, while the second comprises the serializer/deserializer pair with discretionary loop-back. The illustrative embodiment includes a first serializer that serializes a first series of r-bit words to generate a first series of s-bit words, and a first deserializer that deserializes a second series of s-bit words to generate a second series of r-bit words. A multiplexor is also included for selecting a third series of r-bit words from both the first and second series.

Another significant patent by Barnes is focused on "Simplifying the layout of printed circuit boards." This method allows an integrated circuit to modify which pads transport which signals after the integrated circuit has been manufactured. The integrated circuit features a two-dimensional array of pads, with some or all assigned to one or more 'transposition groups' at the design stage. This flexibility enables the transposition of signals carried by those pads, greatly simplifying the layout of a printed circuit board.
