Over the years, successively newer implementations of the same architecture have become several hundreds of times faster than the original and thousands of times faster than the System and power management and built in peripheral and support functions: The processor offered several power-management options e.

The string is copied one byte 8-bit character at a time. Debug registers DR0—DR7 were added for hardware breakpoints.

Intel – Wikipedia

Prior to thethe difficulty of manufacturing microchips and the uncertainty of reliable supply made it desirable that any mass-market semiconductor be multi-sourced, that is, made by two or more manufacturers, the second and subsequent companies manufacturing under license from the originating company.

This provided an upgrade path for users with compatible hardware.

However, this was an annoyance to those who depended on floating-point performance, as the performance advantages of the over the were significant. Retrieved September 17, Introduced Octoberproduction chip in June The bit can correctly execute most code intended for the earlier bit processors such as and that were ubiquitous in early PCs.


The upgrade was a pair of chips that replaced both the and Views Read Edit View history. In MayIntel announced that production would stop at the end of September Several new instructions have been added to datasheeet Samples were produced in possibly late with mass production and delivery of a final version starting in June datashet Retrieved March 15, Part of the problem was that on most motherboards, the A20 line was controlled entirely by the motherboard with the CPU being unaware, which caused problems on CPUs with internal caches.

The added a bit architecture and a paging translation unit, which made it much easier to implement operating systems that used virtual memory.

The Intelalso known as i or justis a bit microprocessor introduced in From Wikipedia, the free encyclopedia.

The i math coprocessor was not ready in time for the introduction of theand so many of the early motherboards instead provided a socket and hardware logic to make catasheet of an The was introduced in Octoberwhile manufacturing of the chips datadheet significant quantities commenced in June IBM was offered use of thebut had manufacturing rights for the earlier AMD introduced its compatible Am processor in March after overcoming legal obstacles, thus ending Intel’s 4.


The architecture was presented in detail in Third parties offered a wide range of upgrades, for both SX and DX systems.

Such chips are now extremely rare and became collectible. Many upgrade kits were advertised as being simple drop-in replacements, but often required complicated software to control the cache or clock doubling.

New forms of MOV instruction are used to access them. For the instruction set first introduced in thesee IA Discontinued BCD oriented 4-bit In other projects Wikimedia Commons.

The following data types are directly supported and datashfet implemented by one or more machine instructions ; these data types are briefly described here.
