The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 [citation needed] and June 8, 1978, when it was released. [5] The Intel 8088, released July 1, 1979, [6] 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 ...
The SDK-86 (system design kit) was the first available computer using the Intel 8086 microprocessor. It was sold as a single board kit at a cheaper price than a single 8086 chip because Intel thought that the success of a microprocessor depends on its evaluation by as many users as possible.
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.
The compromise was an LCD display with electroluminescent backlighting, as well as an increased display line count—25 for the PC-7000 versus the PC-5000's eight. Sharp also replaced the predecessor's Intel 8088 processor with an 8086 running at a user-switchable 7.37 MHz and bumped the stock memory from 128 to 320 KB. These improvements led ...
In marketing, iAPX (Intel Advanced Performance Architecture [1]) was a short lived designation used for several Intel microprocessors, including some 8086 family processors. [2] Not being a simple initialism seems to have confused even Intel's technical writers as can be seen in their iAPX-88 Book where the asterisked expansion shows iAPX to ...
During the mid-1980s NEC and Intel had a long-running US federal court case about microcode copyright. [26] NEC had been acting as a second source for Intel 8086 CPUs with its NEC μPD8086, and held long-term patent and copyright cross-licensing agreements with Intel. In August 1982 Intel sued NEC for copyright infringement over the microcode ...
iRMX – real-time operating system originally created to support the Intel 8080 and 8086 processor families in embedded applications. ISIS , ISIS-II – "Intel Systems Implementation Supervisor" was an environment for development of software within the Intel microprocessor family in the early 1980s on their Intellec Microcomputer Development ...
The original 8086 family of processors relied heavily on segment registers to overcome limitations associated with addressing large amounts of memory via 16-bit registers. The iRMX operating system and the compilers developed for iRMX include features to exploit the segmented addressing features of the original x86 architecture .
