I hate moving. Nothing ever goes as it should. It takes 10 times longer than you expected. And that last box is finally unpacked just before you end up moving again. There's got to be a catch There are 5 CC-states and, depending upon how you count, 6 PC-states in the Penryn line of Intel processors. And, [...]

(update) C-states, C-states and even more C-states

As I said before, a C-state is an idle state. The processor isn't doing anything useful, so why not shut some things off? Think of it in terms of your house. If you're not at home, why keep the lights, radio, and those 6 televisions going? Modern processors have several different C-states representing increasing amounts [...]

C-states are idle states and P-states are operational states. This difference, though obvious once you know, can be initially confusing. With the exception of C0, where the CPU is active and busy doing something, a C-state is an idle state. Since an idle CPU isn't doing anything (i.e. any useful work), why not shut it [...]

I'm writing a white paper on how power management works on Intel processors. This means that I need a forum for airing out my preliminary sections. You guys are it. So if you would be so kind as to "constructively" comment. Feel free to point out bad wording, areas that need clarification, even places where you [...]

T'is the season for holiday, vacations and early Q4 deadlines. 'nough said. Jason: "what can software developers do while they creating the applications to use those hardware components to consume the power? (sic) " There are a variety of things. Intel's focus is on processors, of course. Intel processors, such as the Core Duo, have different operating states [...]

Hello? Is anyone out there? I'm starting up a new blog concerning power issues and application software. I'm Taylor Kidd, an AE (that's Applications Engineer in Intelispeak) in the Intel SSG (Software Solutions Group), more specifically, the PPE (Power Platform Enabling) team. Our mission, since we decided to accept it, is to make venders and those others with [...]
