The disclosed computer-implemented method for multi-lane data bus inversion can include receiving data for transmission via a plurality of data lanes, each data lane corresponding to one of a plurality of inversion bits, and, for each data lane within the plurality of data lanes, applying the corresponding inversion bit to each bit within the data lane. Various other methods, apparatuses, and systems are also disclosed.

Apparatuses, systems, and methods for multi-lane data bus inversion

A processing system includes a pseudo-random bit sequence (PRBS) control unit and a PRBS generator that is used to dynamically generate a PRBS from, for example, a first PRBS and a second PRBS. The PRBS generator is coupled to the PRBS control unit. The PRBS generator generates the second PRBS by dynamically adjusting from a first set of flip-flops of a master set of flip-flops that generate the first PRBS to a second set of flip-flops of the first master set of flip-flops that generate the second PRBS. The PRBS generator includes a plurality of PRBS logic engines coupled to a first PRBS multiplexer, the first PRBS multiplexer being used to select either the first PRBS or the second PRBS that is output by the PRBS generator.
