Abstract
Various energy efficient data encoding schemes and computing devices are disclosed. In one aspect, a method of transmitting data from a transmitter to a receiver connected by plural wires is provided. The method includes sending from the transmitter on at least one but not all of the wires a first wave form that has first and second signal transitions. The receiver receives the first waveform and measures a first duration between the first and second signal transitions using a locally generated clock signal not received from the transmitter. The first duration is indicative of a first particular data value.
Claims11
A method of operating a computing device, comprising:
- selectively operating the computing device in an efficiency-based encoding mode;
- while operating in efficiency-based encoding mode, transmitting data from a transmitter to a receiver connected by plural wires by sending from the transmitter on at least one but not all of the wires a wave form having first and second signal transitions;
- and
- receiving the wave form with the receiver and measuring a first duration between the first and second signal transitions using a locally generated clock signal not received from the transmitter, the first duration being indicative of a first particular data value.
