Eugenia, you shouldn’t even have to warn people about their tone and language with an article like this. I can't speak about FreeBSD, but non-x86 architectures on NetBSD run just as well as x86. Kudos to you, Nicholas, on a well written article. The former may think that this author is simply wrong/incomplete. Effectively both architectures have reached a point where they rely on a RISC core with a translator and interesting caching and processing units to compensate. This “dynamic binary translator” worked in the background to seamlessly translate PowerPC apps to software that could run on Intel’s x86 architecture. These have 8 128 bit registers but operations cannot generally be executed at the same time as floating point instructions. x86 vs ARM on very low power devices. GCC 3.2 for instance produced incorrect code for some PowerPC applications. Obviously readers can find flaws with anything; that’s what the “Comments” area is for after all. This is how the infamous QDOS, MS-DOS’s ancestor, was created, and is part of why Digital Research eventually sued Microsoft: California Computer Systems (if I’m remembering the name right) ran CP/M’s 8080 code through just such a translator, and then wrote a native BDOS for their development system. It is a problem with the x86 architecture that causes context switches to be computationally expensive. ARM processors are designed to be efficient in terms of energy usage. Feel free to draw a different conclusion from these facts. Just that the way it is executed will have to change. The PowerPC gained vector processing in one go when Apple, IBM and Motorola revised the powerPC instruction set and added the Altivec unit which has 32 128 bit registers. Sorry if it doesn’t jive with your revisionist methods of viewing the history of personal computers. A very concise summary of a difficult topic. An instruction converter cannot remove the inherent complexity present in the x86 instruction set and consequently x86 is large and inefficient and is going to remain so. IBM 750xx (G3) ), — PowerPC is now, I believe, Open Hardware (OpenPOWER). I like wasting my time proving people wrong butI don’t like wasting my time for absolutely nothing. I’ve heard(or not heard) several Dells that I could barely tell if they were on or off. . FYI, intel doesn’t have to licence anything to use x86-64. ARM’s low power has enabled battery life an x86 equivalent could merely dream of, whilst its built-in multimedia decoding capabilities enable even 1080p HD video playback in the tiniest of packages relative to the substantial real estate an x86 system would require. The Law of diminishing returns is not exactly a new phenomenon, it was originally noticed in parallel computers by IBM engineer Gene Amdahl, one of creators of the IBM System 360 Architecture. With PPC platform moving towards a solid 64-bit architecture and good multi-processing capabilities, IBM may well have a winner (hopefully it won’t ake long until ther are good 64-bit OS solutions available). The author seems to enjoy making broad statements without providing real proof. Article covering the differences between RISC and CISC This was about the time that general purpose GPU was beginning to be in wide use. Power4 and Itanium both have this and it is how the win the Flop performance benchmarks and marketeering. The x86 architecture as well as several 8-bit architectures are little endian.
