low-power design

Mobile and networking platforms need high bandwidth, low power consumption, and small footprint. These needs drove standards, such as LPDDR4, Wide I/O 2 and Hybrid Memory Cube.

Virtualization makes it possible to run multiple operating system images on one processor core – with benefits for memory protection, power efficiency and cost reduction.

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, […]
