Question: Who led the development of the first microprocessor for the manufacturer of I/O Controller Hub?

full_context: Document 1: 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 2: Ricoh 2A03: The Ricoh 2A03 or RP2A03 (NTSC version) / Ricoh 2A07 or RP2A07 (PAL version) is an 8-bit microprocessor manufactured by Ricoh for the Nintendo Entertainment System video game console. It contained a second sourced MOS Technology 6502 core, modified to disable the 6502's binary-coded decimal mode, with 22 memory-mapped I/O registers that controlled an APU, rudimentary DMA, and game controller polling. It was also used as a sound chip and secondary CPU by Nintendo's arcade games "Punch-Out!!" and "Donkey Kong 3".
Document 3: 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.
Document 4: Computer: The control unit, ALU, and registers are collectively known as a central processing unit (CPU). Early CPUs were composed of many separate components but since the mid-1970s CPUs have typically been constructed on a single integrated circuit called a microprocessor.
Document 5: USB: High-speed USB 2.0 hubs contain devices called transaction translators that convert between high-speed USB 2.0 buses and full and low speed buses. When a high-speed USB 2.0 hub is plugged into a high-speed USB host or hub, it operates in high-speed mode. The USB hub then uses either one transaction translator per hub to create a full/low-speed bus routed to all full and low speed devices on the hub, or uses one transaction translator per port to create an isolated full/low-speed bus per port on the hub.
Document 6: 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 7: 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 8: System Controller Hub: System Controller Hub (SCH) is a family of Intel microchips employed in chipsets for low-power Atom-based platforms. Its architecture is consistent with the Intel Hub Architecture but combines the traditional northbridge and southbridge functions into a single microchip.
Document 9: 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 10: Computer: Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.
Document 11: I/O Controller Hub: I/O Controller Hub (ICH) is a family of Intel southbridge microchips used to manage data communications between a CPU and a motherboard, specifically Intel chipsets based on the Intel Hub Architecture. It is designed to be paired with a second support chip known as a northbridge. As with any other southbridge, the ICH is used to connect and control peripheral devices.
Document 12: 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 13: Phison: Phison Electronics Corporation is a Taiwanese public electronics company that primarily manufactures controllers for NAND flash memory chips. These are integrated into flash-based products such as USB flash drives, memory cards, and solid-state drives (SSDs). Some Sony MicroVault USB sticks and Verbatim Store n Go USB sticks use Phison USB-to-Flash micro-controller ICs.
Document 14: 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 15: 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.
