The configurability of processor IP such as Synopsys' ARC HS family gives designers the option to optimise for power, performance or a combination of both.
Reset is no longer simply an 'X' issue but also feeds into power optimization. Catching issues early greatly speeds verification.
Effective low-power design for embedded-systems will take a new culture of close collaboration between hardware and software engineers.
Problems with process scaling make it seem as though the long era of innovative, lucrative hardware design is coming to an end. But is that really the case?
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.
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, […]
