The Intel 386, originally released as the 80386 and later renamed i386, was the first x86 32-bit microprocessor designed by Intel. Pre-production samples of the 386 were released to select developers in 1985, while mass production commenced in 1986.
The IA-32 architecture defines a 48-bit segmented address format, with a 16-bit segment number and a 32-bit offset within the segment. Segmented addresses are mapped to 32-bit linear addresses. Demand paging 32-bit linear addresses are virtual addresses rather than physical addresses; they are translated to physical addresses through a page table.
The Embeddable Linux Kernel Subset (ELKS), formerly known as Linux-8086, is a Linux-like operating system kernel.It is a subset of the Linux kernel, intended for 16-bit computers with limited processor and memory resources such as machines powered by Intel 8086 and compatible microprocessors not supported by 32-bit Linux.

In 1985, Intel released the 32-bit 80386 (later known as i386) which gradually replaced the earlier 16-bit chips in computers (although typically not in embedded systems) during the following years; this extended programming model was originally referred to as the i386 architecture (like its first implementation) but Intel later dubbed it IA-32 ...
First x86 processor to support SIMD instruction with XMM register implemented, RISC μop decode scheme, integrated register renaming and out-of-order execution. Some important new instructions, including conditional moves, which allow the avoidance of costly branch instructions.
Kali Linux is currently distributed as a 64-bit images for use on hosts based on the x86-64 architecture and as an image for the ARM architecture for use on the Beagle Board computer and Samsung's ARM Chromebook. [19] With the release of 2024.4, 32-bit images based on the i386 architecture were officially dropped. [17] [20]
The Swift community maintains a version which adds support for the language. Free Pascal and the Lazarus IDE can use LLDB as backend for their own FpDebug engine. The LLDB debugger is known to work on macOS, Linux, FreeBSD, NetBSD and Windows, [4] and supports i386, x86-64, and ARM instruction sets. [5] LLDB is the default debugger for Xcode 5 ...
