Intel 80186. Max. CPU clock rate. The Intel 80186, also known as the iAPX 186, [5] or just 186, is a microprocessor and microcontroller introduced in 1982. It was based on the Intel 8086 and, like it, had a 16-bit external data bus multiplexed with a 20-bit address bus. The 80188 variant, with an 8-bit external data bus was also available.
The 8086, 8088, and 80186 have a 20-bit address bus, but the unusual segmented addressing scheme Intel chose for these processors actually produces effective addresses which can have 21 significant bits.
This generational list of Intel processors attempts to present all of Intel 's processors from the 4-bit 4004 (1971) to the present high-end offerings. Concise technical data is given for each product.
The Mindset is an Intel 80186 -based MS-DOS personal computer. [1] It was developed by the Mindset Corporation and released in spring 1984. Unlike other IBM PC compatibles of the time, it has custom graphics hardware supporting a 320×200 resolution with 16 simultaneous colors (chosen from a 512-shade palette) [1] and hardware-accelerated drawing capabilities, including a blitter, [2] allowing ...
The Intel 8088, released July 1, 1979, [ 5 ] is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), [ note 1 ] and is notable as the processor used in the original IBM PC design. The 8086 gave rise to the x86 architecture, which eventually became Intel's most successful line of ...
The x86 instruction set refers to the set of instructions that x86 -compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor.
The Intel 8086, Intel 8088, and Intel 80186 processors had 20 address lines, numbered A0 to A19; with these, the processor can access 2 20 bytes, or 1 MB. Internal address registers of such processors only had 16 bits.
The following is a partial list of Intel CPU microarchitectures. The list is incomplete, additional details can be found in Intel's Tick–tock model, Process–architecture–optimization model and Template:Intel processor roadmap.
