The microprocessor is basically a computer, it is your computer when you take away the screen, keyboard, mouse, and some other parts like ram, hard drive, and the circuit board it self you get this weird chip ( front) called a microprocessor. So the easiest examples for this would be arduino for a micro-controller and your computer or a raspberry pi for the microprocessor. They're often used in things like phones or tablets, where compactness is important but you need more performance than a microcontroller will usually give you. Like microcontrollers, these have a bunch of useful/necessary things built in, but still have a few major components like memory or power management off-chip. Somewhere in between are "systems-on-chip", or SoCs. But it's designed for performance, capability, and expandability rather than price and compactness.
#Difference between microprocessor and microcontroller table plus
A microprocessor like you have in a desktop computer requires a lot of support circuitry just to run, plus bunches of stuff like RAM, a bios, peripheral controllers, bus interfaces, etc., all of which might be on separate chips. They have clock generators, volatile and nonvolatile memory, and a bunch of peripherals that might be handy for interfacing with the outside world, all manufactured on the same chip.Ī microprocessor "just" has the CPU- the machinery that executes code- and some tightly-coupled stuff like caches and memory controllers.
Many microcontrollers don't need any external components once they're programmed, just power and a connection to whatever sensors/actuators they need to do their jobs.
It's designed to be built into some dedicated piece of electronics- maybe it runs your microwave oven, a keyboard or mouse, washing machine, or maybe it controls a subsystem of a larger computer. A microcontroller has more stuff integrated on-chip.
