Presentation on Embedded System and Robotics.

1. EMBEDDED SYSTEMS & ROBOTICS Prof. Anish Goel

2. Embedded Systems We are surrounded by Embedded Systems. Cell Phones Automatic Washing Machines. Traffic Signals with Timers. Automobile Electronics. Find a system that contains no electronic system. How can a electronic system improve the functionality/efficiency of that system. Custom design an embedded system for the same. 2 Embedded Systems & Robotics Anish Goel

3. EMBEDDED SYSTEMS Embedded system means the processor is embedded into that application. An embedded product uses a microprocessor or microcontroller to do one task only. In an embedded system, there is only one application software that is typically burned into ROM. Example：printer, keyboard, video game player 3 Embedded Systems & Robotics Anish Goel

4. MICROPROCESSORS MICRO + PROCESSOR Length of transistor is in micron region. This length becomes half every eighteen months Moore’s Law stated by Gordan Moore. More transistors per chip. 4 Embedded Systems & Robotics Anish Goel

5. Different aspects of a microprocessor/controller Hardware :Interface to the real world Software :order how to deal with inputs 5 Embedded Systems & Robotics Anish Goel

6. Microprocessors: Data Bus CPU General-Purpose Micro-processor Serial COM Port I/O Port RAM ROM Timer Address Bus General-Purpose Microprocessor System General-purpose microprocessor CPU for Computers No RAM, ROM, I/O on CPU chip itself Example：Intel’s x86, Motorola’s 680x0 Many chips on mother’s board 6 Embedded Systems & Robotics Anish Goel

7. Microcontroller : RAM ROM CPU A single chip Serial COM Port I/O Port Timer Microcontroller A smaller computer On-chip RAM, ROM, I/O ports... Example：Motorola’s 6811, Intel’s 8051, Zilog’s Z8 and PIC 16X 7 Embedded Systems & Robotics Anish Goel

8. Basic Microcomputer System. PROCESS INPUT OUTPUT MEMORY 8 Embedded Systems & Robotics Anish Goel

9. Microprocessors and Computer Architecture. What is needed to make systems smart???? Human Brain !!! We are surrounded by microprocessors. Where are they??? In cell phones. In cars. Smallest electronic system you can think of. Largest system you can think of. They are there is Shoes as well. What???? In shoes??? What would a piece of semi-conductor do in a shoes? 9 Embedded Systems & Robotics Anish Goel

10. Why Microprocessors? They will act as brain of the system. They add intelligence to the system. They can be programmed to perform a task. Once programmed, they make the system work automatically. Computer Architecture! Specialized branch that deals with the Microprocessor Architecture. For instance: What is the memory requirement of the system. How many input and output devices are to be connected to the system. 10 Embedded Systems & Robotics Anish Goel
