Four registers are used to refer to four segments on the 16-bit x86 segmented memory architecture. DS (data segment), CS (code segment), SS (stack segment), and ES (extra segment). Another 16-bit register can act as an offset into a given segment, and so a logical address on this platform is written segment:offset, typically in hexadecimal ...
The great leap toward 64-bit computing and the maintenance of backward compatibility with 32-bit and 16-bit software enabled the x86 architecture to become an extremely flexible platform today, with x86 chips being utilized from small low-power systems (for example, Intel Quark and Intel Atom) to fast gaming desktop computers (for example ...
This article describes the calling conventions used when programming x86 architecture microprocessors. Calling conventions describe the interface of called code: The order in which atomic (scalar) parameters, or individual parts of a complex parameter, are allocated; How parameters are passed (pushed on the stack, placed in registers, or a mix ...
Intel's second generation of 32-bit x86 processors, introduced built-in floating point unit (FPU), 8 KB on-chip L1 cache, and pipelining. Faster per MHz than the 386. Small number of new instructions. P5 original Pentium microprocessors, first x86 processor with super-scalar architecture and branch prediction. P6
CPUID model numbers are 60h-6Fh, later updated revisions have model numbers 70h-7Fh. AMD Zen – family of microarchitectures. The successor to Bulldozer. Included in the Ryzen and Epyc CPU lines. AMD Zen Family 17h – first generation Zen architecture based on 14 nm process. First AMD architecture to implement simultaneous multithreading and ...
The internet often has to deal with complex, unstructured data that cannot be relied on to fit a specific data model. The technology of knowledge-based systems, and especially the ability to classify objects on demand, is ideal for such systems. The model for these kinds of knowledge-based internet systems is known as the Semantic Web. [13]
