- Oct 22, 2026 Voltage and Frequency Domains: Why DVFS Is Not One Knob How a frequency change requires a voltage change, why level shifters and synchronisers appear at domain boundaries, and what latency an operating-point transition really costs. computer architecture
- Sep 22, 2026 Thermal Design Power and the Throttling It Authorises What a TDP rating specifies, why a part may exceed it briefly, how the control loop reacts to temperature and current limits, and why two parts with the same TDP perform differently. computer architecture
- Sep 10, 2026 Issue Width and Its Diminishing Returns Why widening an out-of-order issue window costs area and energy faster than it buys performance, and where the wakeup, select, and bypass networks set the ceiling. computer architecture
- Sep 1, 2026 Power Density and the Dark Silicon Constraint Why a chip can contain more transistors than its power budget can switch at once, how that forces area to be specialised, and what fraction of a die can be active at any instant. computer architecture
- 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
- Dec 29, 2025 Clock and Power Gating: Computing the Break-Even Point How gating removes switching power from idle units, what state retention and inrush current cost, and the idle duration at which each form of gating starts to pay. computer architecture
