    Haswell Integrated Power Supplies – A Big Deal for Embedded Systems
    Published. February 17, 2014

    The voltage problem has gotten so bad that it’s not unusual to have 10 or more different voltages on a board, each requiring their own power supply. Intel’s Haswell has a creative solution. To me, embedded computing is an exciting field to be involved in that’s full of interesting applications and constant innovation.  In this […]...

    Intel Xeon Phi Announcement (& me)
    Published. November 24, 2013

    1. No, I’m not dead. Not even sick. Been a long time since a post. More on this at the end.2. So, Intel has finally announced a product ancestrally based on the long-ago Larrabee. The architecture became known as MIC (Many Integrated Cores), development vehicles were named after tiny towns (Knights Corner/Knights Ferry – one was to be the product, but I could never keep them straight), and the final product is to be known as the Xeon Phi.Why Phi? I don’t know. Maybe it’s the start of a convention...
