Difference between microcontrollers an microprocessors ( University of Mauritius IoT workshop 15/2/2020 )
- 1. by Nathan Mangar The difference between a microprocessor and a microcontroller https://tecknologg.website
- 2. Presentation content • Some history on microprocessors and microcontrollers • Their applications • Internal working diagram • Pros and Cons • How do they look like ? • How can we identify them ? • Brief overview on SoCs
- 3. Some history on microprocessors and microcontrollers
- 4. Computers before microprocessors looked like this Vacuum tube based computer
- 5. The first commercially available microprocessor ever made ( 1971 ) INTEL 4004 ( 2300 transistors )
- 6. Over the next years, this lead to • An increase of number bits supported ( 4 bit - 128bit ) • An increase of the number of transistors in Intergrated circuits • Creation of new variants of microprocessors and CPU architectures such as 8051, ARM and so on. • Creation of new semiconductor companies ( Cyrix, Zilog ) • The creation of Microcontrollers
- 8. Applications of Microprocessors Applications of Microcontrollers • Desktop computers • Laptops • Supercomputers • Anything that requires a lot of computing power • Industrial equipment • Robotics • IoT devices • Smart devices
- 10. Internal diagram of a microcoprocessor and microcontroller Note : The architecture may not be the same
- 11. Pros and Cons
- 12. Pros and cons of microcontrollers Pros Cons They are cheaper They can do a very limited number of tasks Much more compact Limited peripherals Take less board space Limited RAM and ROM ( some microcontrollers support expandable ROM )
- 13. Pros and cons of microprocessors Pros Cons They can perform tasks that require a lot of computing power Takes a good amount of board space Have the ability to run graphical interfaces Most modern processors need a heatsink or fan as it can get hot Ability to expand the memory and peripherals They're not cheap
- 14. How do they look like ?
- 15. Examples of how they might look like Microprocessors Microcontrollers
- 16. How can we identify them ?
- 17. How to know if it's a microprocessor or a microcontroller ? 1. Look at the chip number 2. Then look for the datasheet ( Datasheets contain certain information and technical details )
- 18. Part 01 Add your title Brief overview on SoCs ( System on Chip)
- 19. Products that use SoCs The Raspberry Pi Smartphones
- 21. SoCs • Consume less power ( good for battery powered systems ) • Can perform a lot of functions ( USB, Camera and so on ) • Compact • But requires external RAM and ROM
- 22. Part 01 Add your title Questions ?
- 23. Thank you for listening https://tecknologg.website
