Definition Embedded system: any device that includes acomputer but is not itself a general-purposecomputer. Application specific The design is specialized and optimized for specificapplication Don’t need all the general-purpose bells and whistles.ECE 1161/2161 Embedded Computer System Design 27
Examples of Embedded Systems Cellphone, Personal Digital Assistant (PDA)Printer.GPS.Automobile: engine, brakes, dash, etc.Digital camera.iPod.Household appliances: microwave, air conditioningWrist watch.and a lot more Fact: 95% of all microprocessors are used forembedded systems.ECE 1161/2161 Embedded Computer System Design 28
Anti-Lock Brake System Pumps brakes to reduce skidding. Real-time and rakesensorsensorECE 1160/2160 Embedded Systems Design9
Automotive Systems A high-end car may have 100 microprocessors: 4-bit microcontroller checks seat belt; microcontrollers run dashboard devices; 16/32-bit microprocessor controls engine; Navigation; Entertainment: DVD, audio, satellite radio Future Cars may drive by themselves? Control your car by speaking out, or even your mindECE 1160/2160 Embedded Systems Design10
Other examples Simple control Front panel of microwave oven Digital control of air conditioning Canon EOS 3 has three microprocessors. 32-bit RISC CPU runs autofocus and eyecontrol systems. Sony BRAVIA LCD TV has a standalonemicroprocessor for image processing BRAVIA Engine 2 Full 1080p video streaming: highthroughput requiredECE 1160/2160 Embedded Systems Design11
Why are those systems special? Application specific Specialize and optimize the design for specific application Not a general-purpose computer. Don’t need all the bells and whistles, e.g., hard drive, monitor, keyboard Have to worry about both hardware and software Have to worry about non-functional constraints Real-time Memory footprint Power Reliability and safety CostJust functionally working is NOT enough!ECE 1161/2161 Embedded Computer System Design 212
