A microprocessor is an integrated circuit which contains and has all the functions of a whole CPU in one single IC.
CPU –(Central Processing Unit) Carries out the same process as a microprocessor but is larger, less effective and costlier.
IC –(Integrated Circuit) A collection of electronic parts and/or substances.
Microprocessors are made with things such as silicone, quartz, various metals and some chemicals. Because of this and their size, they take around about 2 months to make a single one. There are two types of microprocessors: CICS and RISC. Microprocessors are able to be recycled also! This system includes Resistors, Diodes and Transistors that all work together to work the computer. Transistors can be less than 1 micrometre wide and are mostly MOSFETs. Now you can see why they take around about 2 months to make such a small object! Also, because of their size, moving from a bulky CPU system to a microprocessor reduces the cost of making and selling and due to this, it also increases efficiency.
Types of Microprocessors:
DSP – (Digital Signal Processor) Is used and specialized for the processing of signals.
GPU – (Graphics Processing Unit) Are heavily used for real time 3-D Imaging such as in gaming.
Others – Are used for things such as video processing and machine vision.
Microprocessors use the same system as CPU’s :
Fetch Decode Execute
Takes the Instruction. Figures out the instructions. Preforms the operation.
What are the uses for a microprocessor?
Washing Machines – controls amount of water/display/ ensures wash cycles are done correctly.
Hairdryers – Controls flow of air and temperature.
Remote Control Television – DPS controls/transfers signal between remote and TV.
Digital Ballasts – Configure lamp type and make adjustments accordingly.
Electrical Kettles – DPS sends signal to turn on or off heat/records temperature.
Laptops/PC’s – Runs everything! The processing of signal, video, imaging and reactions.
Alarm Systems (Burglar) – Dependant on type, signals on or off and responds to movement, light or sound.
