1. A method, comprising:
- propagating electronic signals within circuitry comprising a transmitter to perform a configuration method that includes;
selecting a number of lanes, said lanes emanating from said transmitter;
setting a speed for each of said lanes, said number and speed determining said transmitter'"'"'s bandwidth; and
,setting a driver supply voltage for each of said lanes wherein, power consumed by said transmitter as a consequence of said selecting a number of said lanes, said setting a speed for each of said lanes and said setting a driver supply voltage foreach of said lanes is less than a power that would have been consumed by said transmitter had another available combination of lane number, lane speed and supply voltage been effected for said transmitter.

Abstract
A method is described which comprises propagating electronic signals within circuitry comprising a transmitter to select a number of the transmitter'"'"'s lanes, set a speed for each of the lanes, and set at least a driver supply voltage for each of the lanes. The number and speed determine the transmitter'"'"'s bandwidth. Power consumed by the transmitter as a consequence of the lane number selection, lane speed setting and driver supply voltage is less than a power that would have been consumed by the transmitter had another available combination of lane number, lane speed and supply voltage been effected for the transmitter.

8. A method, comprising:
-
as a consequence of turning a computing system on, loading information from a read only memory (ROM); propagating electronic signals within circuitry of said computing system that includes a transmitter to perform a configuration method that includes; selecting a number of lanes, said lanes emanating from said transmitter; setting a speed for each of said lanes, said number and speed determining said transmitter'"'"'s bandwidth; and
,setting a driver supply voltage for each of said lanes wherein, power consumed by said transmitter as a consequence of said selecting a number of said lanes, said setting a speed for each of said lanes and said setting a driver supply voltage for each of said lanes is less than a power that would have been consumed by said transmitter had another available combination of lane number, lane speed and supply voltage been effected for said transmitter, said number of lanes, said speed and said driver supply voltage being determined from said information.
