История развития компьютеров (Silicon Valley, its history the best companies) (стр. 3 из 6)
Fairchild Semiconductor focused on building a marketable silicon transistor applying a new manufacturing process called "mesa". Despite being the smallest company in electronics business then, it attracted public attention, particularly in 1958, when "Big Blue" - as dominant IBM is nicknamed - ordered the "first-ever mesa silicon transistors") for memory drivers in its computers.
This order contributed to the early success of Fairchild Semiconductor, and indicated the beginning of a long relationship between IBM and Silicon Valley.
Importance of military funding
Before switching over to the events at Intel, the aspect of military funding is to be dealt with, since it has played an important role in the early days of Silicon Valley.
During World War II, after the Japanese attack at Pearl Harbor in 1942, a great deal of the U.S. military forces and of the military production was moved to California. Within a few years, California - formerly an agricultural state - became a booming industrial state and the military center of the USA.)
After the war, in the time of the Cold War and the arms race, the Korean conflict, the "missile gap" and the space program, the Pentagon kept ordering high-technology products from the armament factories in California. Many companies established R&D departments and production facilities in Santa Clara County near Stanford University, which provided them with bright engineers and scientists, and were largely supported by the Pentagon's demand for electronic high-tech products.
Examples for such firms are FMC, GTE, Varian Associates, Westinghouse, and finally Lockheed, which opened its R&D department in the Stanford Research Park in 1956, and started Lockheed Missiles and Space Company (LMSC) in Sunnyvale. Lockheed's move to Northern California was crucial for the developments in Santa Clara County; today the company is Silicon Valley's largest employer with more than 24,000 people.)
Military funding for high-tech products was responsible for the early growth of Silicon Valley in the 1950s and 1960s. The U.S. Department of Defense was the biggest buyer of these products, e.g. its purchases represented about 70 percent of the total production of ICs in 1965.)
While this share in chip demands has dropped to 8 percent today, the Pentagon remains the biggest supporter of new technologies and accounts for most of the purchases of the latest developments.
Intel Corp.
After the transistor and the integrated circuit, the invention of the microprocessor in the early 1970s represents the next step towards the modern way of computing, providing the basis for the subsequent personal computer revolution.
It was at Intel where the first microprocessor was designed - representing the key to modern personal computers. With its logic and memory chips, the company provides the basic components for microcomputers. Intel is regarded as Silicon Valley's flagship and its most successful semiconductor company, owing its worldwide leading role to a perpetually high spending on research and development (R&D).
It all started in 1968, when Bob Noyce resigned as head of Fairchild Semiconductor taking along Gordon Moore and Andy Grove, to embark on a new venture. They had decided to leave the company, because they wanted "to regain the satisfaction of research and development in a small, growing company,") since Fairchild had become big with lots of bureaucracy work to be done. Gordon Moore had belonged to the famous Shockley Eight and was in charge of the R&D team at Fairchild. Andy Grove, a young Hungarian émigré, who had earned a doctorate in chemical engineering at U.C. Berkeley, had joined Fairchild in the early 1960s.
Intel (short for Integrated Electronics), a typical Fairchild spin-off, was financially backed by venture capital from Arthur Rock, who had been in contact with Noyce since 1957. The company was founded upon the idea of integrating many transistors on a chip of silicon, after Noyce had developed a new photochemical process. The three engineers initially focused on building the first semiconductor chips used for computer memory, which should replace the dominant memory storage technology at the time, called "magnetic core". Intel's task was to drive down the cost per bit by increasing the capacity of memory chips dramatically.
Within a year, Intel developed its first product - the 3101 Schottky bipolar 64-bit static random access memory (SRAM), which was followed soon after by the 1101. This chip (1101) was a 256-bit SRAM and had been developed on Intel's new "silicon gate metal -oxide semiconductor (MOS) process," which should become the "industry's process technology of choice.") With the first two products, the young company started with 12 employees and net revenues of $2,672 in 1968, had already gained the technological lead in the field of memory chips.
Intel's first really successful product was the 1103 dynamic random access memory (DRAM), which was manufactured in the MOS process. Introduced in 1970, this chip was the "first merchant market LSI (large-scale integrated) DRAM," and received broad acceptance because it was superior to magnetic core memories. So, by the end of 1971, the 1103 became "the world's largest-selling semiconductor device" and provided the capital for Intel's early growth.)
Until today, semiconductors have "adhered to Moore's Law," which has been framed by the "cofounder of Fairchild and Intel" when the first commercial DRAMs appeared in the early 1970s. This law predicts that the price per bit (the smallest unit of memory) drops by 30 percent every year. It implies that you will receive 30 percent more power (speed/capacity) at the same price, or that the "price of a certain power is 30 percent less.")
Moore's Law applies to both memory chips and microprocessors, and shows the unprecedented rapid progress in microelectronics. This "astonishing ratio" has never occurred in "the history of manufacturing" before. Applied to automobiles, it means that "a Cadillac would have a top speed of 500 miles per hour, get two hundred miles to a gallon of gas and cost less than a dollar" - almost incredible.)
1971 was a crucial year at Intel. The company's revenues surpassed operating expenses for the first time, and the company went public, raising $6.8 million.
Moreover, the company introduced a new memory chip - the first erasable, programmable read only memory (EPROM). Invented by Intel's Dov Frohman, the new memory could store data permanently like already existing ROMs, but besides could be erased simply by a beam of ultraviolet light and be used again. The EPROM was initially viewed as a "prototyping device" for R&D. The invention of the microprocessor in the same year, however, showed the real significance of the EPROM, which could be used by original equipment manufacturer (OEM) customers (they build the end-products) to store microprocessor programs in a "flexible and low-cost way." The "unexpected synergy" between the EPROM and the microprocessor resulted in a growing market for both chips and contributed a great deal to Intel's early success.)
"Ted" Hoff's first microprocessor
The invention of the microprocessor marked a turning point in Intel's history. This development "changed not only the future of the company, but much of the industrial world.")
The story to this technological breakthrough began in 1969, when a Japanese calculator manufacturer called Busicomp asked Intel to design a set of chips for a family of programmable calculators. Marcian "Ted" Hoff, a young and "very bright ex-Stanford research associate") who had joined Intel as employee number 12, was charged with this project. However, he did not like the Japanese design calling for 12 custom chips - each of them was assigned a distinct task. Hoff thought designing so many different chip s would make the calculators as expensive as minicomputers such as DEC's PDP-8, although they could merely be used for calculation. His idea was to develop a four-chip set with a general-purpose logic device as its center, which could be programmed by inst ructions stored on a semiconductor memory chip. This was the theory behind the first microprocessor.
With the help of new employee Stan Mazor, Hoff perfected the design of what would be the 4004 arithmetic chip. After Busicomp had accepted Hoff's chip set, Frederico Faggin, one of the best chip design experts, who had been hired recently, began transforming the design into silicon. The 4004 microprocessor, a 4-bit chip (processes 4 bits - a string of four ones or zeroes - of information at a time), contained 2300 MOS transistors, and was as powerful as the legendary first electronic computer, ENIAC.
Soon after the first 4004s had been delivered to Busicomp, Intel realized the market potential of the chip, and successfully renegotiated with the Japanese to regain the exclusive rights, which had been sold to Busicomp.
In November 1971, Intel introduced the 4004 to the public in an Electronic News ad. It announced not just a new product, but "a new era of integrated electronics [...], a micro programmable computer on a chip.") The microprocessor is - as Gordon Moore call s it - "one of the most revolutionary products in the history of mankind,") and ranks as one of 12 milestones of American technology in a survey of U.S. News and World Report in 1982. This chip is the actual computer itself: It is the central processing u nit (CPU) - the computer's brains. The microprocessor made possible the microcomputer, which is "as big as it is only to accommodate us." For "we'd have a hard time getting information into or out of a microprocessor without a keyboard, a printer and a terminal," as Th.Mahon puts it.)
However significant Hoff's invention, nevertheless, it was hardly noticed in the public until early 1973. The microprocessor had its own instruction set and was to be programmed in order to execute specific tasks. So Ted Hoff had to inform the public and t he engineers about the capabilities of the new device and how to program it.
Cooperation with IBM in the 1980s
Intel's measures in the late 1970s as a reaction to increasing competition from other chip manufacturers paid off greatly and resulted in a remarkable technological lead against its competitors. The most significant consequence, which was a landmark in the company's development, was IBM's decision to rely on the Intel 8088 microprocessor for its PCs in 1980.
IBM (short for International Business Machines) has been the world's leading company in the big mainframe computers since the 1950s. Due to its dominance, it was often compared with a giant and referred to as "Big Blue." Surprisingly, it was not before 198 1 (the PC revolution had already been on for a few years) that IBM introduced its own Personal Computer.
Because of IBM's dominance and worldwide reputation, its PCs soon became industry standard and penetrated the office market: other established computer companies followed and introduced their own PCs - the so-called "clones" - which were compatible to IBM' s models. To maintain compatibility, all these manufacturers were forced to rely on Intel's microprocessors, which thus were bootstrapped to industry standard, too.
As well as for Intel, the CPU manufacturer, IBM's decision has been crucial for a company in the software field: Microsoft's (Redmond, Washington) MS-DOS was chosen as the IBM PC's operating system and became industry standard. It is essential to every IBM compatible PC. Microsoft, a small company in 1980, grew explosively, and is today's superior software giant.
At the beginning of the 1980s, IBM was concerned about Intel's ability to keep investing in R&D and therefore decided to support Intel by buying $250 million (=12%) of the company's stock. This endorsed Intel's position, and, in 1987, IBM sold the last of its shares in a strong Intel.
