Patent ID: 8363538

Claim:
An orthogonal data link, comprising: a first digital device; a second digital device; and a bus coupling the first digital device to the second digital device; the first digital device having a first transmitter for encoding first data with a first code for transmission on the bus, the second device having a second transmitter for encoding second data with a second code for transmission on the bus, the encoding of the first data being asynchronous to the encoding of the second data, the first device having a first receiver for decoding the second data with the second code, the second device having a second receiver for decoding the first data with the first code, the first and second codes being substantially orthogonal with one another, the first code comprising N 1s and no 0s, the second code comprising N/2 1s and N/2 0s, N being an even integer greater than or equal to 2.
