Abstract: Methods and apparatus relating to an adaptive multibit bus for energy optimization are described. In an embodiment, a 1-bit interconnect of a processor is caused to select between a plurality of operational modes. The plurality of operational modes comprises a first mode and a second mode. The first mode causes transmission of a single bit over the 1-bit interconnect at a first frequency and the second mode causes transmission of a plurality of bits over the 1-bit interconnect at a second frequency based at least in part on a determination that an operating voltage of the 1-bit interconnect is at a high voltage level and that the second frequency is lower than the first frequency. Other embodiments are also disclosed and claimed.

Abstract: By shutting off keeper transistors during pre-charge, the aging on these devices may be reduced. This means that a relatively weaker keeper may be used for noise compared to an overdesigned stronger keeper. Using a relatively weaker keeper circuit results in a faster evaluation stage and improved minimum read voltage in some embodiments.

Abstract: A pulse triggered flip flop circuit includes an exclusive OR clock generating stage that receives an input clock, data and produces an output clock pulse. The stage produces a output clock pulse that only goes away when the data is fully captured. The stage disables the output clock pulse only when the data is fully captured. Moreover, the circuit only toggles when the input data changes, reducing power consumption in some embodiments.
