Nvidia patents chip design that sends data without a clock
Nvidia has been granted a patent for an integrated circuit that uses logic gates to send data in a continuous stream without needing a traditional clock signal to synchronize it. The design includes a specific circuit that prepares the data based on timing, along with components that manage the speed of the data flow.
In the filing’s own words
An integrated circuit includes logic circuitry configured to output serialized data from a plurality of precoded data inputs without use of a clock signal. The integrated circuit further includes a precoder circuit responsive to the clock signal to generate the plurality of precoded data inputs based on timing of data symbols positioned within a plurality of data inputs.
What exactly they claim (claim 1)
1. An integrated circuit comprising: logic circuitry configured to output serialized data from a plurality of precoded data inputs without use of a clock signal; a precoder circuit responsive to the clock signal to generate the plurality of precoded data inputs based on timing of data symbols positioned within a plurality of data inputs; and one or more multiplexers positioned between a retimer circuit and the precoder circuit, wherein multiplexing by the one or more multiplexers is at least one of: a lowest available data rate of a plurality of retimed data inputs; or a reduced data rate compared to a data rate of the serialized data.
