- Jun 20, 2026 Energy-Optimal Operating Points and the Shape of DVFS Why the lowest voltage a circuit can run at is not the most efficient one, how frequency and voltage must move together, and where the energy minimum sits for a real workload. hardware engineering
- Mar 4, 2026 The Power Wall: Why Frequency Scaling Stopped How dynamic power depends on voltage and frequency, why Dennard scaling ended when the supply voltage stopped falling, and what replaced clock rate as the source of throughput. computer architecture
- Feb 25, 2026 Heterogeneous Cores and the Area-Performance Frontier Why a large core and a small core can be combined to beat either alone, how area efficiency curves determine the mix, and what thread migration costs. computer architecture
- Feb 8, 2023 Specialisation as an Energy Strategy Why a fixed-function unit beats a general-purpose core on energy per operation, how Amdahl and utilisation bound the payoff, and what the built-in generality of a core is worth. computer architecture
