Nazwa x86 w odniesieniu do modelu programowego procesorów dotyczy pierwszych procesorów tego typu – od 8086 do 286, które były układami o architekturze 16-bitowej. Obecnie systemy i oprogramowanie 32-bitowe, często przyjmują oznaczenie x86 (procesory 16-bitowe wyszły z użycia).
Jak sprawdzić, czy na komputerze jest uruchomiona 32-, czy 64-bitowa wersja systemu Windows?
19 wrz 2015 · x32 is an ABI for amd64/x86_64 CPUs using 32-bit integers, longs and pointers. The idea is to combine the smaller memory and cache footprint from 32-bit data types with the larger register set of x86_64.
IA-32 (short for "Intel Architecture, 32-bit", commonly called i386 [1] [2]) [3] is the 32-bit version of the x86 instruction set architecture, designed by Intel and first implemented in the 80386 microprocessor in 1985.
9 mar 2024 · The key difference between x86 and x64 lies in their data handling capacity. While x86 systems are based on 32-bit architecture, x64 systems operate on 64-bit architecture. This allows x64 processors to access over a billion gigabytes of memory and undertake complex tasks like 3D graphics rendering and managing large databases more efficiently.
On the x86 architecture, a 32-bit application normally means software that typically (not necessarily) uses the 32-bit linear address space (or flat memory model) possible with the 80386 and later chips.
Although most x86 processors used in new personal computers and servers have 64-bit capabilities, to avoid compatibility problems with older computers or systems, the term x86-64 (or x64) is often used to denote 64-bit software, with the term x86 implying only 32-bit.
