Dynamic voltage scaling with links for power optimization of interconnection networks
TLDR
In this paper we motivate the use of dynamic voltage scaling (DVS) for links, where the frequency and voltage of links are dynamically adjusted to minimize power consumption. Expand

Express virtual channels: towards the ideal interconnection fabric
TLDR
We propose express virtual channels, a novel flow control mechanism which allows packets to virtually bypass intermediate routers along their path in a completely non-speculative fashion, thereby lowering the energy/delay towards that of a dedicated wire while simultaneously approaching ideal throughput with a practical design suitable for on-chip networks.

A study of the energy consumption characteristics of cryptographic algorithms and security protocols
TLDR
We investigate the impact of various parameters at the protocol level (such as cipher suites, authentication mechanisms, and transaction sizes, etc.) and the cryptographic algorithm level (cipher modes, strength) on the overall energy consumption for secure data transactions. Expand
