摘要： Dynamic bus inversion (DBI) for programmable levels of a ratio of ones and zeros. A transmitting device identifies a number and/or ratio of ones and zeros in a noninverted version of a signal to be transmitted (“noninverted signal”) and a number and/or ratio of ones and zeros in an inverted version of the signal (“inverted signal”). The transmitting device can calculate whether a difference of ones and zeros in the noninverted signal or a difference of ones and zeros in the inverted signal provides a calculated average ratio of ones to zeros closer to a target ratio. The transmitting device sends the signal that achieves provides the calculated average ratio closer to the target ratio.
