Bit inversion for data transmission

Abstract:

In certain aspects, a method for sending data over a bus comprises: calculating a parity check code for a new data code, wherein the new data code comprises a number of bits in the new data code; calculating a Hamming distance between the new data code and a prior data code; and if the Hamming distance is greater than half of the number of bits in the new data code: inverting the new data code and the parity check code to obtain an inverted new data code and an inverted parity check code; and sending the inverted new data code and the inverted parity check code to the bus.
