x86arkitekturer

x86arkitekturer refers to a series of instruction set architectures (ISA) used in microprocessors, developed by Intersil (later acquired by Zilog) and licensed to Intel and other companies. The x86 architecture was designed to run MS-DOS, a popular operating system for personal computers in the 1980s.

The original x86 architecture, known as 8086, was introduced by Intel in 1978. It was an 8-bit processor but was capable of processing 16-bit addresses. The 8086 processor had a 16-bit data bus, addressing 1 MB of memory, and a clock speed of up to 8 MHz.

Later improvements led to the introduction of the 80386 processor, a 32-bit RISC (Reduced Instruction Set Computing) architecture, which provided improved performance and supported larger memory addresses. The 80386 processor was released in 1985 and featured a clock speed of up to 20 MHz.

The x86 architecture continued to evolve with the introduction of the 80486 processor in 1989, which provided improved performance and integrated onto a single chip many of the components that were previously separate, such as the math coprocessor (wanted as FPU, floating point unit).

The increasing demands of modern computing led to the development of newer x86 architectures, such as the Pentium processor (1993), the Core 2 processor (2006), and more recent developments such as Multi-Core processors and those from the newer i7 series.

The x86 architecture has become the de facto standard for modern computing, used in desktops, laptops, and servers, as well as in embedded systems and other applications. Its adaptability and_years of continuous improvement have made it a widely influential and widely popular computer architecture.
