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 iAPX 432 was referred to as a "micromainframe", designed to be programmed entirely in high-level languages. [4] [5] The instruction set architecture was also entirely new and a significant departure from Intel's previous 8008 and 8080 processors as the iAPX 432 programming model is a stack machine with no visible general-purpose registers.
Die of AMD 8088. The 8088 was designed at Intel's laboratory in Haifa, Israel, as were a large number of Intel's processors. [9] The 8088 was targeted at economical systems by allowing the use of an eight-bit data path and eight-bit support and peripheral chips; complex circuit boards were still fairly cumbersome and expensive when it was released.
The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released. 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 front-side bus (FSB) is a computer communication interface that was often used in Intel-chip-based computers during the 1990s and 2000s. The EV6 bus served the same function for competing AMD CPUs. Both typically carry data between the central processing unit (CPU) and a memory controller hub, known as the northbridge. [1]
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 ...
Bus (computing) In computer architecture, a bus[1] (historically also called data highway[2] or databus) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
Support status. Unsupported. The Intel 486, officially named i486 and also known as 80486, is a microprocessor. It is a higher-performance follow-up to the Intel 386. The i486 was introduced in 1989. It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386.
