  2. Definition Embedded System • Embedded system (Wikipedia) An embedded system is a computer system with a dedicated function within a larger electrical system, often with realtime constraints Embedded systems contain processing cores that are either microcontrollers, microprocessors or digital signal processors A processor is an important unit in the embedded system hardware. It is the heart of the embedded system ES - Version 2.0

  3. Definitions • Microprocessor (P) A microprocessor is the central unit of a computer. Direct at this CPU memory is integrated and threre are interfaces to further circuit modules. (for example: Pentium, Athlon, PPC, ...) • Digital Signal Processor (DSP) A digital signal processor is a special system for execution of time sensitive- and computionally intensive recurring tasks. (for example : TMS320, Sharc, DSP56xx, Tricore, ...) • Microcontroller (C) Microcontroller are processors, which posseses a lot of peripheral devices (peripherals) beside of CPU and memory on the chip, to due take over a lot of controlling tasks in an „embedded system“. For example: ( C164, 8051, 68HC11, PIC, mpc55xx,...). ES - Version 2.0
