Question: Who introduced the first microprocessor for the company Virtutech is part of in 1971?

full_context: Document 1: Insight Communications: On August 13, 2011, Time Warner Cable (which was acquired by Charter Communications in 2016) announced its purchase of Insight Communications for $3 billion. The sale will create cost efficiencies of approximately $100 million annually through savings on programming expenses and other cost reductions, with the bulk of the savings realized within two years of the close of sale. With Insight's 2011 conversion of its television services from analog to digital, Time Warner Cable expects Insight to have lower capital requirements of 10-12% of revenues upon completion of the acquisition, which is subject to approval by the Federal Communications Commission and Insight franchisees. The merger was completed February 29, 2012. On March 9, 2013, letters were sent to Insight customers informing them that starting in June 2013, Insight Communications will be completely absorbed, and Insight service will be replaced by Time Warner Cable. Former Insight customers continue to be able to utilize their former 'insightbb.com' email addresses through Time Warner Cable's email system.
Document 2: Virtutech: On February 5, 2010, Intel announced that it had acquired Virtutech and that Simics will now be maintained by Intel's subsidiary Wind River Systems. The price of the acquisition was $45M.
Document 3: Tecnomatix: In 2005, Tecnomatix was acquired by the UGS Corporation and the Tecnomatix product was combined with UGS' existing MPM solutions. The current Tecnomatix software line includes Part Manufacturing, Assembly Planning, Resource Planning, Plant Simulation, Human Performance, Quality, Production Management, Manufacturing Data Management.
Document 4: Home computer: The invention of the Intel 8080 microprocessor chip in April 1974 made practical the development of the (relatively) affordable mass - market microcomputer. In the USA this first appeared in early 1975 in the form of an unassembled kit, the Altair 8800; shortly afterward pre-assembled Altairs were offered. The sudden popularity of desktop computers happened because the 8080 CPU could represent and manipulate 256 discrete values in its 8 - bit registers. Thus the 7 - bit ASCII standard for the representation of alphanumeric data became feasible for the first time in a machine much smaller and less expensive than the furniture - size minicomputers, with their processors that occupied entire circuit boards. This new class of computer was practical for serious work because it could input, process, and output alphanumeric information. It also enabled sophisticated programs such as database managers and BASIC interpreters to become available to a larger market consisting of people possessing lesser technical skills.
Document 5: Computer: The next great advance in computing power came with the advent of the integrated circuit. The idea of the integrated circuit was first conceived by a radar scientist working for the Royal Radar Establishment of the Ministry of Defence, Geoffrey W.A. Dummer. Dummer presented the first public description of an integrated circuit at the Symposium on Progress in Quality Electronic Components in Washington, D.C. on 7 May 1952.
Document 6: Computer: This new development heralded an explosion in the commercial and personal use of computers and led to the invention of the microprocessor. While the subject of exactly which device was the first microprocessor is contentious, partly due to lack of agreement on the exact definition of the term "microprocessor", it is largely undisputed that the first single-chip microprocessor was the Intel 4004, designed and realized by Ted Hoff, Federico Faggin, and Stanley Mazor at Intel.
Document 7: List of acquisitions by Hewlett-Packard: After this two-year gap, in 2014, HP returned to the acquisition market by acquiring Computer Networking Software company Shunra. The majority of companies acquired by HP are based in the United States.
Document 8: Tukwila (processor): The Itanium 9300 series, code-named Tukwila, is the generation of Intel's Itanium processor family following Itanium 2 and Montecito. It was released on 8 February 2010. It utilizes both multiple processor cores (multi-core) and SMT techniques. The engineers said to be working on this project were from the DEC Alpha project, specifically those who worked on the Alpha 21464 (EV8), which was focused on SMT.
Document 9: Intel 4004: The chip design started in April 1970, when Federico Faggin joined Intel, and it was completed under his leadership in January 1971. The first commercial sale of the fully operational 4004 occurred in March 1971 to Busicom Corp. of Japan for which it was originally designed and built as a custom chip. In mid-November of the same year, with the prophetic ad ``Announcing a new era in integrated electronics '', the 4004 was made commercially available to the general market. The 4004 was the first commercially available monolithic CPU, fully integrated in one small chip. Such a feat of integration was made possible by the use of the then - new silicon gate technology for integrated circuits, originally developed by Faggin (with Tom Klein) at Fairchild Semiconductor in 1968, which allowed twice the number of random - logic transistors and an increase in speed by a factor of five compared to the incumbent MOS aluminum gate technology. Faggin also invented the bootstrap load with silicon gate and the`` buried contact'', improving speed and circuit density compared with aluminum gate.
Document 10: Computer: The first practical ICs were invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor. Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". Noyce also came up with his own idea of an integrated circuit half a year later than Kilby. His chip solved many practical problems that Kilby's had not. Produced at Fairchild Semiconductor, it was made of silicon, whereas Kilby's chip was made of germanium.
Document 11: CMOS: Complementary metal–oxide–semiconductor (CMOS) is a technology for constructing integrated circuits. CMOS technology is used in microprocessors, microcontrollers, static RAM, and other digital logic circuits. CMOS technology is also used for several analog circuits such as image sensors (CMOS sensor), data converters, and highly integrated transceivers for many types of communication. Frank Wanlass invented CMOS in 1963 while at Fairchild Semiconductor and was granted US patent 3,356,858 in 1967. In this groundbreaking patent, the fabrication of CMOS devices was outlined, on the basis of thermal oxidation of a silicon substrate to yield a layer of silicon dioxide located between the drain contact and the source contact .
Document 12: Personal computer: 1974 saw the introduction of what is considered by many to be the first true ``personal computer '', the Altair 8800 created by Micro Instrumentation and Telemetry Systems (MITS). Based on the 8 - bit Intel 8080 Microprocessor, the Altair is widely recognized as the spark that ignited the microcomputer revolution as the first commercially successful personal computer. The computer bus designed for the Altair was to become a de facto standard in the form of the S - 100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.
Document 13: Microprocessor: By the late 1960s, designers were striving to integrate the central processing unit (CPU) functions of a computer onto a handful of MOS LSI chips, called microprocessor unit (MPU) chipsets. Building on an earlier Busicom design from 1969, Intel introduced the first commercial microprocessor, the 4 - bit Intel 4004, in 1971, followed by its 8 - bit microprocessor 8008 in 1972. In 1969, Lee Boysel, b 8 - bit arithmetic logic units (3800 / 3804) he designed earlier at Fairchild, created the Four - Phase Systems Inc. AL - 1, an 8 - bit CPU slice that was expandable to 32 - bits. In 1970, Steve Geller and Ray Holt of Garrett AiResearch designed the MP944 chipset to implement the F - 14A Central Air Data Computer on six metal-gate chips fabricated by AMI.
