Hotspot hot potato

Normally, silicon scaling is a good thing. Except when you are making power devices, as people working in the automotive semiconductor business explained at the Design Automation and Test in Europe (DATE) conference this week in Dresden. Klaus Meder, president of the automotive electronics division at Robert Bosch, explained in…

MSP430 clones explore limits of MCU power

The Texas Instruments MSP430 is practically synonymous with low-power processors and, although the company may not care much for the idea of clones of the architecture appearing, that is being helped by a crop of research processors that explore the limits of the threshold voltage of CMOS transistors. These…

Clock-speed slowdown continues

It’s no secret that the clock speeds of processors have hit a glass ceiling. But until the latest iteration of the International Technology Roadmap for Semiconductors, we still expected them to increase by close to 10 per cent a year. Not anymore. The slow rise has been replaced by…

ITRS 2011 published

The 2011 International Technology Roadmap for Semiconductors (ITRS), finalised late last year, has been publicly released. The roadmap looks at the problems facing the chipmaking industry from now until 2026 and includes some updates that focus on low-power design. The slides prepared by Andrew Kahng on design, for example…

Measurement is key, but can you get the measurements?

Low-Power Engineering has posted the last instalment of its round-table interviews on making software more energy efficient and some of the problems that face an industry that needs to expose low-level hardware details through a compiler-insulated interface…

The unpredictable world of x86 energy consumption

Power consumption is hard to predict even with a reasonable amount of architectural information and that is underlined in a paper that appeared at the Architectural Support for Programming Languages and Operating Systems (ASPLOS) conference last April. but recently picked up by LinuxDevices. In the paper, the researchers argue that…
