A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. [2] The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). [ 3 ]
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.
Affordable 8-bit microprocessors with 16-bit addressing also led to the first general-purpose microcomputers from the mid-1970s on. The first use of the term "microprocessor" is attributed to Viatron Computer Systems [18] describing the custom integrated circuit used in their System 21 small computer system announced in 1968.
An 8-bit register can store 2 8 different values. The range of integer values that can be stored in 8 bits depends on the integer representation used. With the two most common representations, the range is 0 through 255 (2 8 − 1) for representation as an binary number, and −128 (−1 × 2 7) through 127 (2 7 − 1) for representation as two's complement.
The Altair 8800 is a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU. [2] Interest grew quickly after it was featured on the cover of the January 1975 issue of Popular Electronics [3] and was sold by mail order through advertisements there, in Radio-Electronics, and in other hobbyist magazines.
Ratzenberger then explained that for him, this archetype can be traced to a man named Sarge, whom he encountered often at his dad's go-to bar growing up. Eric Charbonneau/Getty John Ratzenberger ...
The AVR is a modified Harvard architecture machine, where program and data are stored in separate physical memory systems that appear in different address spaces, but having the ability to read data items from program memory using special instructions.
