The Intel 8085 ("eighty-eighty-five") is an 8-bit microprocessor produced by Intel and introduced in March 1976. [2] It is the last 8-bit microprocessor developed by Intel. It is software-binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features.
The Intel MCS-51 (commonly termed 8051) is a single chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the Intel MCS-51 instruction set was John H. Wharton. [ 1 ][ 2 ] Intel's original versions were popular in the 1980s and early 1990s, and enhanced binary compatible derivatives remain ...
The Kenbak-1 is an 8-bit computer programmed in pure machine code using an array of buttons and switches. Output consisted of a row of lights. It was first sold in early 1971. Since the Kenbak-1 was invented before the first microprocessor, the machine didn't have a one-chip CPU but was instead based purely on small-scale integration TTL chips ...
The microprocessor is a multipurpose, clock -driven, register -based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results (also in binary form) as output.
1990s. The 32-bit microprocessor dominated the consumer market in the 1990s. Processor clock speeds increased by more than tenfold between 1990 and 1999, and 64-bit processors began to emerge later in the decade. In the 1990s, microprocessors no longer used the same clock speed for the processor and the RAM.
The MCS-48 microcontroller series, Intel 's first microcontroller, was originally released in 1976. Its first members were 8048, 8035 and 8748. The 8048 [1] is arguably the most prominent member of the family. Initially, this family was produced using NMOS (n-type metal–oxide–semiconductor) technology. In the early 1980s, it became ...
The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released. The Intel 8088, released July 1, 1979, [5] is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), [note 1] and is notable as the processor used in the original IBM PC design.
A Special Function Register (or Special Purpose Register, or simply Special Register) is a register within a microprocessor, which controls or monitors various aspects of the microprocessor's function. Depending on the processor architecture, this can include, but is not limited to: I/O and peripheral control (such as serial ports or general ...
