Near-threshold and subthreshold logic

By taking the circuit supply voltage close to that of the threshold voltage or even below, it is possible to optimize low-power VLSI design. But there are pitfalls.

Reset optimization pays big dividends before simulation

Reset is no longer simply an 'X' issue but also feeds into power optimization. Catching issues early greatly speeds verification.

The power-aware OS

The article describes the context and need for embedded operating systems that are more responsive to the power management demands placed on today’s electronic devices. It reviews the design objectives for the two main types of power management, reactive and proactive, and examines how both can be implemented. For system developers designing portable electronic devices, […]
