The company’s first product was the chip of RAM (random-access memory), and it soon became a leader in this market in the 1970s. Simultaneously, Intel engineers Marcian Hoff, Federico Faggin, Stanley Mazor and Masatoshi Shima invented the first microprocessor. Originally developed for the Japanese company Busicom to replace ASIC’s calculator has delivered Busicom, the Intel 4004 was introduced on the market for mass production in November 15, 1971, though the microprocessor did not become the core business of Intel until mid-1980 (Note: Intel is usually given credit with Texas Instruments for the almost-simultaneous invention of the microprocessor).
In 1983, the dawn of the personal computer era, Intel’s profits came under increased pressure from Japanese manufacturers of memory integrated circuits, and then-President Andy Grove decided to run the company with a focus on microprocessors. A key element of his plan was the intention, then considered radical, of becoming the single source for successors to the popular 8086 microprocessor. It launched the 8088 processor, which was a huge success for the computers recently launched IBM’s first PC’s. Later came others who gained more resources and greater processing speed, then known as belonging to the family of x86 processors. But when launching the fourth processor that should be called 80586, eventually creating the Intel Pentium trademark (although the label 80586, better known as 586, have been applied long for competitors of the Company).
Until then, the manufacture of complex integrated circuits was not reliable enough for customers to depend on a single supplier, but Grove began producing processors in three geographically distinct factories, and ceased licensing microprocessor designs to competitors such as Zilog and AMD. When the PC industry exploded in the 1980s and early 1990s, Intel was one of the most benefit.
During the 1990s, Intel Architecture Labs (Intel Architecture Labs – IAL) was responsible for many innovations in the structure of the personal computer, including the PCI bus, PCI Express (PCIe), the Universal Serial Bus (Universal Serial Bus – ‘USB’), and now the dominant architecture for users of Multiprocessor the x86.
