Moore's law Moore's law Moore's law is the observation that the number of transistors in a dense integrated circuit doubles about every two years. The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and Intel, whose 1965 paper described a doubling every year in the number of components per integrated circuit, and projected this rate of growth would continue for at least another decade. In 1975, looking forward to the next decade, he revised the forecast to doubling every two years. The period is often quoted as 18 months because of a prediction by Intel executive David House (being
Intel iAPX 432 operated as a channel controller for I/O, and an Attached Processor (AP), a conventional Intel 8086 which provided "processing power in the I/O subsystem". These were some of the largest designs of the era. The two-chip GDP had a combined count of approximately 97,000 transistors while the single chip IP had approximately 49,000. By comparison, the Motorola 68000 (introduced in 1979) had approximately 40,000 transistors. In 1983, Intel released two additional integrated circuits for the iAPX 432 Interconnect Architecture: the 43204 Bus Interface Unit (BIU) and 43205 Memory Control Unit (MCU). These chips allowed for nearly glueless multiprocessor systems with
