Power- and Performance - Aware Architectures
(Universitat Politècnica de Catalunya, 2004-06-14)
Doctoral thesis
Open AccessThe scaling of silicon technology has been ongoing for over forty years. We are on the way to commercializing devices having a minimum feature size of one-tenth of a micron. The push for miniaturization comes from the ... -
Power-constrained aware and latency-aware microarchitectural optimizations in many-core processors
(Universitat Politècnica de Catalunya, 2016-10-05)
Doctoral thesis
Open AccessAs the transistor budgets outpace the power envelope (the power-wall issue), new architectural and microarchitectural techniques are needed to improve, or at least maintain, the power efficiency of next-generation processors. ... -
Predicated execution and register windows for out-of-order processors
(Universitat Politècnica de Catalunya, 2008-11-18)
Doctoral thesis
