The Intel 4004 is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. Sold for US$60 (equivalent to $450 in 2023 [2]), it was the first commercially produced microprocessor, [3] and the first in a long line of Intel CPUs.
Intel's Ted Hoff was assigned to studying Busicom's design, and came up with a much more elegant, 4 ICs architecture centered on what was to become the 4004 microprocessor surrounded by a mixture of 3 different ICs containing ROM, shift registers, input/output ports and RAM—Intel's first product (1969) was the 3101 Schottky TTL bipolar 64-bit ...
The 4004 had a single ROM pin, whereas the 4040 added another ROM pin to allow two banks of ROM. This effectively increased the ROM address from 12 to 13 bits, or 8 kB. Unlike later designs where the two lines could be binary encoded and thus support four banks, the ROM chips used with the 4004 and 4040 used these lines like chip select pins ...
As of 2020, the x86 architecture is used in most high end compute-intensive computers, including cloud computing, servers, workstations, and many less powerful computers, including personal computer desktops and laptops.
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
The CADC was a multi-chip integrated flight control system developed by Garrett AiResearch and used in early versions of the US Navy's F-14 Tomcat fighter. It is notable for early use of MOS custom integrated circuits and has been claimed as the first microprocessor chipset. [2]
the 4004 chip usually has multiple 4004 chips with even more of the matching rom,ram and IO-modules on the same board. The 4004 chip is a multi-processor chip by being only 4-bit. Synchronization is more important on 4-bit instruction sets and a higher synchronization frequency will easily randomize some communication processes.
The Xerox Alto is a computer system developed at Xerox PARC (Palo Alto Research Center) in the 1970s. It is considered one of the first workstations or personal computers, and its development pioneered many aspects of modern computing.
