Energy Consumption for Transport of Control Information on a Segmented Software-Controlled Communication Architecture
The segmented bus is a power-efficient architecture for intra-tile SoC communication, where energy is saved by switching off
unused bus segments cycle-by-cycle. We determine the pattern of switch control bits and calculate the cost of transporting
them. A test case indicates that the cost is much lower than the gain obtained from the segmentation, and that the prospects
of segmented buses remain promising.
