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 4040 DIP chip pinout. The 4040 was essentially an expansion of the 4004, with additional pins, more registers and new instructions to take advantage of both. 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.
A sample network diagram Readily identifiable icons are used to depict common network appliances, e.g. routers, and the style of lines between them indicates the type of connection. Clouds are used to represent networks external to the one pictured for the purposes of depicting connections between internal and external devices, without ...
The first commercial microprocessor was the binary-coded decimal (BCD-based) Intel 4004, [2] [3] developed for calculator applications in 1971; it had a 4-bit word length, but had 8-bit instructions and 12-bit addresses. It was succeeded by the Intel 4040, which added interrupt support and a variety of other new features.
Intel Haswell Core i7-4771 CPU, sitting atop its original packaging that contains an OEM fan-cooled heatsink. This generational list of Intel processors attempts to present all of Intel's processors from the 4-bit 4004 (1971) to the present high-end offerings.
The first single core processor was the Intel 4004, which was commercially released on November 15, 1971 by Intel. [4] Since then many improvements have been made to single core processors, going from the 740 kHz of the Intel 4004 to the 2 GHz Celeron G470.
The first series of Intellecs included the Intellec 4 for the 4004, the Intellec 4 Mod 40 for the 4040, the Intellec 8 for the 8008, and the Intellec 8 Mod 80 for the 8080. [2] The Intellec 4 and 8 were introduced at the June 1973 National Computer Conference in the New York Coliseum. [3]
The network on chip is a router-based packet switching network between SoC modules. NoC technology applies the theory and methods of computer networking to on-chip communication and brings notable improvements over conventional bus and crossbar communication architectures .
