Embedded microprocessors and embedded microcontrollers are similar but different at the same time. Both have the ability to run a task. But the microcontroller is more of a self sufficiant computer than the microprocessor. The microprocessor is more of a the component that drives your computer.

A microprocessor is a computer processor on a microchip. It's sometimes called a logic chip. It is the "engine" that goes into motionwhen yopu turn your computer on. A microprocessor is designed to perform arithmetic and logic operations that make use of small number-holding areas called registers. Typical microprocessor operations include adding, subtracting, comparing two numbers, and gathering numbers from one place and moving it to another. These operations are the results of a set of instructions that are part of the microprocessor design. When the computer is turned on, the microprocessor is designed to get the first instruction from the Basic Input/Output System (BIOS) that comes with the computer as part of its memory. After that either the BIOS, the operating system that BIOS loads into memory, or an application program is "driving" the microprocessor. One of the former are giving the microprocessor instructions to perform.

A microcontrolller is a highly integrated chip that contains all the components comprising a controller. Typically this includes a CPU, RAM, some form of ROM, IO ports, and timers. Unlike a general-purpose computer, which also includes all of these components, a microcontroller is designed for a very specific task. They are generally used to control a particular system. As a result, the parts can be simplified and reduced, which cuts down on production costs. For both microprocessors and microcontrollers embedded mean that they are part of a larger system.

The microprocessor bus discussed most often is the data bus; the bundle of wires (or pins) used to send and receive data. The more si...
