Abstract
Embodiments of the invention generally provide methods, systems, and articles of manufacture for selecting a data bus inversion (DBI) mode of operation. A comparison circuit of a device may receive multiple packets of data to be transmitted to another device over a bus connecting the devices. The comparison circuit may compare the multiple packets of data and select a DBI mode of operation that conserves power and reduces noise on the bus.
