Encoding of symbols for a computer interconnect based on frequency of symbol values

A method comprising:

• identifying, by a training unit of a decoder, a frequency of each symbol value in a first set of encoded symbol values in a first epoch, wherein each symbol has one of at least four possible values;
• and
• in a second epoch:
• decoding each symbol of another set of symbol values based on the identified frequency of each respective symbol value in the first set of symbol blocks of the first epoch;
• and
• communicating, across the interconnect, each encoded symbol value.

A system for serially communicating data as symbols over an interconnect, the system comprising:

• an encoder including:
• a first training unit to identify a frequency of symbol values of a first set of symbol blocks in a first epoch, wherein respective symbol values encode one of a plurality of at least four possible symbol values;
• and
• in a second epoch subsequent in time to the first epoch, encoding each symbol of another set of symbol blocks based on the frequency of each respective symbol value in the symbol blocks of the first epoch;
• and
• a transmitter coupled to the encoder and the interconnect, wherein the transmitter transmits the encoded symbols onto the interconnect.

A system, comprising:

• a receiver;
• and
• a decoder coupled to receive symbols over an interconnect via the receiver, wherein the decoder includes:
• a training unit to identify the frequency of symbol values of the set of symbol blocks for a first epoch;
• wherein the decoder is to decode received symbol values of a second epoch based on the identified frequency of symbol values;
