Since the introduction of the first commercially available microprocessor ( the Intel 4004 ) in 1970, and the first widely used microprocessor ( the Intel 8080 ) in 1974, this class of CPUs has almost completely overtaken all other central processing unit implementation methods.

A PDP-10, a PDP-8, an Intel 386, an Intel 4004, a Motorola 68000, a System z mainframe, a Burroughs B5000, a VAX, a Zilog Z80000, and a 6502 all vary wildly in the number, sizes, and formats of instructions, the number, types, and sizes of registers, and the available data types.

The Intel 4004 was a 4-bit processor released in 1971, but in 1973 the Intel 8080, an 8-bit processor, made the first personal computer, the Altair 8800, possible.

Being within an hours ' drive of Silicon Valley, Kildall heard about the first commercially available microprocessor, the Intel 4004.

The technology was developed by Italian physicist Federico Faggin in 1968, who later joined Intel in order to develop the very first Central Processing Unit ( CPU ) on one chip ( Intel 4004 ), for which he received the National Medal of Technology and Innovation in 2010.

Intel 4004, the first general-purpose, commercial microprocessor

The first single-chip microprocessor was the 4-bit Intel 4004 released in 1971, with the Intel 8008 and other more capable microprocessors becoming available over the next several years.

* 1971 – Intel releases world's first commercial single-chip microprocessor, the 4004.

** Intel releases the world's first microprocessor, the Intel 4004.

* 10 µm — transistor width of the Intel 4004, the world's first commercial microprocessor

The first microprocessor for example, the Intel 4004, was designed for calculators and other small systems but still required many external memory and support chips.

While it contains no microprocessor, it used the 4004 programming instruction set and its custom TTL was the basis for the Intel 8008, and for practical purposes the system behaves approximately as if it contains an 8008.

Zilog was incorporated in California in 1974 by Federico Faggin, who left Intel after working on the 4004 and then the 8080 microprocessors.

Six months later, Seiko approached Intel expressing an interest in using the 1201 in a scientific calculator, likely after seeing the success of the simpler Intel 4004 used by Busicom in their business calculators.

The 8008 was a little slower in terms of instructions per second ( 36, 000 to 80, 000 at 0. 8 MHz ) than the 4-bit Intel 4004 and Intel 4040, but the fact that the 8008 processed data eight bits at a time and could access significantly more RAM still gave it a significant speed advantage in most applications.

** Hal Feeney project engineer did the detailed logic design, circuit design, and physical layout under Faggin's supervision, employing the same design methodology that Faggin had originally developed for the Intel 4004 microprocessor, and utilizing the basic circuits he had developed for the 4004.

Because the WD1770 is capable of single density mode and uses the same IBM360 derived floppy disc format as the Intel 8271 found in the BBC Micro, it was also possible to run a DFS filing system with an alternate ROM, such as the P. R. E. S AP4 interface.

Per a News article on Page # 9 of the October 1984 issue of Acorn User, the Plus 3 was originally destined to have used the Intel 8272 disk controller, ( and not 8271, which were in short supply at the time ).

Finally a replacement for the aging Z80 processor was being developed in the form of an Intel 8086 board, and additional 512K 16 bit memory boards.

By working with Motorola, AMD was able to refine copper interconnect manufacturing to the production stage about one year before Intel.

While the K6 FPU had looked anemic compared to the Intel P6 FPU, with Athlon this was no longer the case.

In commercial terms, the Athlon " Classic " was an enormous success — not just because of its own merits, but also because Intel endured a series of major production, design, and quality control issues at this time.

Due to Apple's moves and the mounting debt of Be Inc., BeOS was soon ported to the Intel x86 platform with its R3 release in March 1998.

The first highly ( or tightly ) pipelined x86 implementations, the 486 designs from Intel, AMD, Cyrix, and IBM, supported every instruction that their predecessors did, but achieved maximum efficiency only on a fairly simple x86 subset that was only a little more than a typical RISC instruction set ( i. e. without typical RISC load-store limitations ).

The Intel P5 Pentium generation was a superscalar version of these principles.

The DragonBall's major design win was in earlier versions of the Palm Computing platform ; however, from Palm OS 5 onwards it has been superseded by ARM-based processors from Texas Instruments and Intel.

For example, Forth was the first resident software on the new Intel 8086 chip in 1978 and MacFORTH was the first resident development system for the first Apple Macintosh in 1984.

FORTH, Inc .' s microFORTH was developed for the Intel 8080, Motorola 6800, and Zilog Z80 microprocessors starting in 1976.

It was not until the launch of the Intel i486 in 1989 that general-purpose personal computers had floating point capability in hardware as standard.

This was based on a proposal from Intel who were designing the i8087 numerical coprocessor.

Windows 3. 0 could run in real, standard, or 386 enhanced modes, and was compatible with any Intel processor from the 8086 / 8088 up to the 80286 and 80386.

Windows XP Professional x64 Edition is not to be confused with Windows XP 64-bit Edition, as the latter was designed for Intel Itanium processors.

IA-32 ( Intel Architecture, 32-bit ), also known as x86-32, i386 or x86, is the CISC instruction-set architecture of Intel's most commercially successful microprocessors, and was first implemented in the Intel 80386 as a 32-bit extension of x86 architecture.

The IA-32 instruction set was introduced in the Intel 80386 microprocessor in 1986 and remains the basis of most PC microprocessors over twenty years later.

The Intel 80286 ( also called iAPX 286 ), introduced on 1 February 1982, was a 16-bit x86 microprocessor with 134, 000 transistors.

In theory, real-mode applications could be directly executed in 16-bit protected mode if certain rules were followed ; however, as many DOS programs broke those rules, protected mode was not widely used until the appearance of its successor, the 32-bit Intel 80386, which was designed to go back and forth between modes easily.

* The world ’ s first microprocessor ( 1971 ) was made possible by the advanced capabilities of the silicon gate technology, the Intel 4004 was a 4-bit CPU ( central processing unit ) on a single chip.

The Intel Pentium MMX, Pentium II and Pentium III have local branch predictors with a local 4-bit history and a local pattern history table with 16 entries for each conditional jump.

The first commercial microprocessor was the binary coded decimal ( BCD-based ) Intel 4004, developed for calculator applications in 1971 ; it had a 4-bit word length, but had 8-bit instructions and 12-bit addresses.

The Intel 4004, the world's first commercially available single-chip microprocessor, was a BCD-based 4-bit CPU.

Pentium 4 was a line of single-core desktop and laptop central processing units ( CPUs ), introduced by Intel on November 20, 2000 < ref >

* Northwood, a central processing unit ( CPU ) core series produced by Intel

It uses an Intel 8086 central processing unit that operates at 5MHz, which also the 8086 gave rise to the x86 architecture of Intel's future processors.

* P5 ( microarchitecture ), Intel Pentium, 5th generation central processing unit introduced in 1993

* Intel Pentium II, 6th generation central processing unit

The HP 200LX has an Intel 80186 compatible embedded central processing unit named " Hornet ", which runs at ~ 7. 91 megahertz ( which can be upgraded or overclocked to up to 15. 8 MHz ) and 1 to 4 MB of memory, of which 640 KB is RAM and the rest can be used for expanded memory ( EMS ) or memory-based storage space.
