DVFS is Dead, Long Live Holistic DVFS

An industry survey some three years ago indicated only about one-quarter of all chip designers were using dynamic voltage and frequency scaling (DVFS). It’s likely most of those people who said they were implementing DVFS are deeply dependent upon a mobile operating system. For instance, Android offers a range of CPU governor software modules to […]

Taking Energy Back from Next-Generation MCU Designs

Microamp-per-megahertz thinking served the microcontroller (MCU) community well for decades. As the focus shifts to connectivity and always-on use cases, bigger cores and wireless IP blocks push energy use in the wrong direction. Next-generation MCUs can ill afford to spend more energy just to manage themselves. Any mandatory software to make an MCU run usually […]

Free Trial Explores EPU IP and Automation

Last summer at 53DAC in Austin, Sonics rolled out a seminar with a formative strategy for its Energy Processing Unit, or EPU. After that session, I summarized the idea in my SemiWiki blog: “The premise of an EPU is that power savings using software, even in a dedicated microcontroller, is relatively slow, perhaps 50 to […]
