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. Pre-production samples of the 386 were released to select developers in 1985, while mass production ...
The primary defining characteristic of IA-32 is the availability of 32-bit general-purpose processor registers (for example, EAX and EBX), 32-bit integer arithmetic and logical operations, 32-bit offsets within a segment in protected mode, and the translation of segmented addresses to 32-bit linear addresses. The designers took the opportunity ...
The instructions are usually part of an executable program, often stored as a computer file and executed on the processor. The x86 instruction set has been extended several times, introducing wider registers and datatypes as well as new functionality.
The family comprised the Intel Inboard 386/AT and Intel Inboard 386/PC, which allowed users to upgrade an IBM AT or an IBM PC (or compatible) respectively. The boards allowed users to upgrade their machines' CPU to a 16 MHz 80386 processor. Both variants utilized a ribbon cable which plugged into the computer's original CPU socket on one end ...
The Intel 486, officially named i486 and also known as 80486, is a microprocessor introduced in 1989. It is a higher-performance follow-up to the Intel 386.It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386.
Introduced in September 1986, the Deskpro 386 was the first personal computer to feature Intel's 32-bit 80386 microprocessor. It also marks the first time that a major component of the IBM Personal Computer de facto standard was updated by a company other than IBM themselves—in this case, upgrading from the 80286 processor of the Personal ...
The Personal System/2 Model 60 is a high-end desktop computer in IBM's Personal System/2 (PS/2) family of personal computers. First released in April 1987, the Model 60 features an Intel 80286 processor running at a clock speed of 10 MHz, the same as its midrange counterpart, the Personal System/2 Model 50.
The Sun386i (codenamed Roadrunner) is a discontinued hybrid UNIX workstation/PC compatible computer system produced by Sun Microsystems, launched in 1988. [1] It is based on the Intel 80386 microprocessor but shares many features with the contemporary Sun-3 series systems.
