μC/OS-III offers all of the features and functions of μC/OS-II. The biggest difference is the number of supported tasks. μC/OS-II allows only 1 task at each of 255 priority levels, for a maximum of 255 tasks. μC/OS-III allows any number of application tasks, priority levels, and tasks per level, limited only by processor access to memory.
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 ]
Some designs include general-purpose microprocessor cores, with one or more ROM, RAM, or I/O functions integrated onto the package. Other designs are purpose-built for control applications. A microcontroller instruction set usually has many instructions intended for bit manipulation (bit-wise operations) to make control programs more compact ...

one card (shown right) with the I/O part of the computer: a LED seven segment display, a 25-key keypad (hex+function keys), and a cassette CUTS interface (the circuitry to the left of the keypad) the second card (the computer board - see below), which included the CPU, RAM/ROM memory, and support chips
Designers in the late 1960s were striving to integrate the central processing unit (CPU) functions of a computer onto a handful of MOS LSI chips, called microprocessor unit (MPU) chipsets. While there is disagreement over who invented the microprocessor, [ 2 ] [ 14 ] the first commercially available microprocessor was the Intel 4004 , released ...
In the BBC Microcomputer System, the Tube is the expansion interface and architecture which allows the BBC Micro to communicate with a second processor, or coprocessor. Under the Tube architecture, the coprocessor runs the application software for the user, whilst the Micro (acting as a host ) provides all I/O functions, such as screen display ...
VisiCalc ("visible calculator") [1] is the first spreadsheet computer program for personal computers, [2] originally released for the Apple II by VisiCorp on October 17, 1979. [1] [3] It is considered the killer application for the Apple II, [4] turning the microcomputer from a hobby for computer enthusiasts into a serious business tool, and then prompting IBM to introduce the IBM PC two years ...
