The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor from Intel. It was the first 32-bit processor in the line, making it a significant evolution in the x86 architecture.
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 Intel Inboards allowed users to run 386-dependent software which would not normally run on an XT or AT class machine. Examples of such programs include: Ventura 2.0 Desktop Publishing Software (with Hercules monochrome graphics), AutoCAD 386, Windows 3.1 (Inboard 386/AT model only).
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 ...
The P75 was a released in 1990 upgraded version of P70 model, and is noted as being the first portable computer using a 486 CPU to be available for sale in the United States. It had a briefcase-shaped design and ran off A/C power only, as was common with high performance portable computers at the time.
Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
VIA chipsets support CPUs from Intel, AMD (e.g. the Athlon 64) and VIA themselves (e.g. the VIA C3 or C7).They support CPUs as old as the i386 in the early 1990s. In the early 2000s, their chipsets began to offer on-chip graphics support from VIA's joint venture with S3 Graphics beginning in 2001; this support continued into the early 2010s, with the release of the VX11H in August 2012.
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]
