They're all good. In today's world of SoC the architecture of the CPU usually, but not always, takes second or third place when comparing features like the peripheral set, Pd and package alternatives. Afterall, all Boole, et al left us with is AND and NOT...everything else is but a variation on a theme.
From tiny acorns do giant oaks ( ARM ) grow ! Ironic that de-industrialized and uncompetitive England provided a more fertile soil for RISC designs to grow than out here in the desert in the shadow of giant Fabs that are still churning out CISC processors with a billion transistors. But for how long ?
Nice article. I was around when much of this was happening and had heard a bit about Acorn computers but was mostly unaware of how it all fit together.
I especially like this statement: 'Wilson concludes: "Hermann Hauser says he gave us the things Intel could never give us, no resources, no time and no money."'
How many great innovations have happened because someone had a job to do and not enough time, resources or money to do it?
I give ARM good marks for seeing a development path beyond the Intel line. Intel followed a logical path exploiting their processor line into the home PC market.
ARM saw the long term potential of building a path towards customizable computer processor components to enable smaller runs of targeted processors.
I am impressed with the quality and versatility of the ARM processor line. They may now face more competition from Intel as the PC market begins to phase down. The capability to make building block components has been around for a while, so it will be interesting to see if Intel can come up with a competitive alternative.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
