“Eagle” Cycle-Accurate Simulator Anno 1979

I recently read the classic book The Soul of a New Machine by Tracy Kidder. Even though it describes the project to build a machine that was launched more than 30 years ago, the story is still fresh and familiar. Corporate intrigue, managing difficult people, clever engineering, high pressure, all familiar ingredients in computing today just as it was back then. With my interesting in computer history and simulation, I was delighted to actually find a simulator in the story too! It was a cycle-accurate simulator of the design, programmed in 1979.

Some Fun Cache Results from Carbon

Carbon Design Systems have been on a veritable blogging spree recently, pushing out a large number of posts around various topics. Maybe a bit brief for my taste in most cases (I have a tendency to throw out 1000+ word pseudo-articles when I take the time to write a blog), but sometimes very interesting nevertheless. I particularly liked a few posts on cache analysis, as they presented some good insight into not-quite-expected processor and cache behaviors.

Wind River Blog: Inside the Simics QSP – Additional Notes

There is a new post at my Wind River blog, about the design and technical contents of the new Simics Quick Start Platforms, more widely known as the QSP. The blog describes the virtual-only hardware that forms part of the QSP, and how it was designed. It is interesting to note that the hardware ended up a bit more complex that I initially thought it would be, since an ideal virtual platform should be very simple. Right? Turns out an OS complicates things.

Off-topic: Society without God

I just finished reading Society without God, by American sociologist Phil Zuckerman. The book came out back in 2008, but I heard about it recently on a skeptic podcast and I felt I just had to buy it. Phil Zuckerman spent a year in Denmark in 2006, and also visited Sweden during that time to perform interviews with a wide sample of what seems to me to be typical Swedes and Danes, trying to understand their attitude towards god and religion. His conclusion is that the Nordic countries today are a special little area of deep secularism in a world that is mostly religious and apparently growing more religious recently. Even in fairly secularized Western Europe, the Nordic countries stand out (or at least Denmark and Sweden does, in his research). So what? For a Swede like myself this is pretty obvious… but when you combine this with the fact that the standard of living and overall feeling of security and quality of life in Denmark and Sweden is very high, Zuckerman finds a great argument against a certain argument brought forth by Christian conservatives in the US…
