Boosting Battery Life For RISC Processors

Posted by ryuzaki0 on from the staying-unplugged-longer dept.

prostoalex writes "National Semiconductor and ARM Holdings will jointly develop the power management solution for RISC chips, that they estimate will improve battery life by 25-400%. The target date of the first sample product is Q2 2003." My old Tadpole laptop sure could have used this. I counted myself as lucky when I got a whole 45 minutes out of a battery.

  1. They're ripping off Transmeta by SexyKellyOsbourne · · Score: 2, Offtopic

    According to the article:

    Arm's Intelligent Energy Manager solution implements advanced algorithms to optimally balance processor workload and energy consumption, while maximizing system responsiveness to meet end-user performance expectations.

    Transmeta's only claim to fame for their chips was using software to reduce power consumption, and it worked -- obviously, the Intelligent Energy Manager is just a ripoff of Transmeta's design. Linus should sue.

    > Windows: reboot for the changes to take effect.

    > Linux: Download, compile, install, and reboot with the latest kernel.

    I disagree.

    Windows: Click start->Windows updates, download 50 megabytes of patches, accept license agreement (you read it, right?), install and reboot.

    Linux (Debian): "apt-get update". Proceed.

    Sure, you should reboot on kernel upgrades but seriously - who upgrades their kernel every week?
