Abstract
An interface device transforms data to a packet and inverts at least a portion of the packet to reduce a number of bit toggles at corresponding locations in a previous packet. A reverse bit appended to the packet indicates whether the packet is inverted. A transmission packet including the reverse bit and the portion of the packet inverted according to a state of the reverse bit is transmitted, and the data are recovered from a received packet, the portion of which that was inverted is inverted again according to the state of the reverse bit.
