Adaptive multibit bus for energy optimization

A method comprising:

• causing a 1-bit interconnect of a processor to select between a plurality of operational modes, wherein the 1-bit interconnect comprises a transmission line, wherein the plurality of operational modes comprises a first mode and a second mode, wherein the first mode causes transmission of a single bit over the 1-bit interconnect at a first frequency,
• wherein the first mode is to cause transmission of a single bit over the transmission line at a first frequency and a first operating voltage level, wherein the second mode is to cause transmission of two bits over the transmission line at a second frequency and a second operating voltage level, wherein the second frequency is lower than the first frequency and second operating voltage level is higher than the first operating voltage level.

One or more non-transitory computer-readable medium comprising one or more instructions that when executed on at least one processor configure the at least one processor to perform one or more operations to:

• cause a 1-bit interconnect of the processor to select between a plurality of operational modes, wherein the 1-bit interconnect comprises a transmission line, wherein the plurality of operational modes comprises a first mode and a second mode,
• wherein the first mode is to cause transmission of a single bit over the transmission line at a first frequency and a first operating voltage level, wherein the second mode is to cause transmission of two bits over the transmission line at a second frequency and a second operating voltage level, wherein the second frequency is lower than the first frequency and second operating voltage level is higher than the first operating voltage level.
