Warum ist ARM Besser als X86?
Die ARM-Architektur ist deutlich „schlanker“ und effizienter. Der Nutzer kann das System jedoch nicht beliebig erweitern. Die x86-Architektur, wie sie von Intel und AMD produziert wird, ermöglicht mehr Freiheiten in Bezug auf Betriebssysteme und Anwendungen, wodurch die Risiken eines Ausfalls steigen.
Was bedeutet ARM Computer?
ARM stand für Acorn RISC Machines, später für Advanced RISC Machines. Obwohl der Name außerhalb der IT-Fachwelt wenig bekannt ist, gehören Implementierungen dieses Typs weltweit zu den meistverbreiteten Mikroprozessoren.
What is the difference between x86 and x64?
X64 vs x86, which one is better? The x86 (32 bit processors) has a limited amount of maximum physical memory at 4 GB, while x64 (64 bit processors) can handle 8, 16 and some even 32GB physical memory. In addition, a 64 bit computer can work with both 32 bit programs and 64 bit programs.
When was the first x86 64 bit processor released?
AMD Opteron, the first CPU to introduce the x86-64 extensions in 2003 The five-volume set of the x86-64 Architecture Programmer’s Guide, as published and distributed by AMD in 2002 x86-64 (also known as x64, x86_64, AMD64 and Intel 64) is a 64-bit version of the x86 instruction set, first released in 1999.
What is x86-64 instruction set?
x86-64 is an extension of the x86 instruction set. It supports vastly larger virtual and physical address spaces than are possible on x86, thereby allowing programmers to conveniently work with much larger data sets. x86-64 also provides 64-bit general purpose registers and numerous other enhancements.
What is the kernel stack size of x86_64 bit?
Kernel stacks on x86-64 bit ¶ Most of the text from Keith Owens, hacked by AK x86_64 page size (PAGE_SIZE) is 4K. Like all other architectures, x86_64 has a kernel stack for every active thread. These thread stacks are THREAD_SIZE (2*PAGE_SIZE) big.
