Abstract: A device includes a driver circuit to send data bits onto a data bus that is partitioned into a DC component and an AC component. The driver circuit is to, for some data bits, retrieve a value of a DC power ratio of the data bus. The driver circuit is further to determine, using the value of the DC power ratio, a first value for a first portion of total power to be dissipated over the DC component to transmit the data bits, and determine, using one minus the value of the DC power ratio, a second value for a second portion of total power to be dissipated over the AC component to transmit the data bits. The driver circuit is to determine whether to send the data bits onto the data bus using data bus inversion dependent on a combination of the first value and the second value.

Abstract: Embodiments may relate to a processor to an electronic device that includes an error correction code (ECC) encoder that is to perform ECC encoding on aa data message to generate an ECC encoded data message. The electronic device may further include a data bus inversion (DBI) encoder communicatively coupled with the ECC encoder, wherein the DBI encoder is to perform DBI encoding on the ECC encoded data message to generate a DBI encoded data message. Other embodiments may be described or claimed.
