  1. Introduction CS423 Dick Steflik Embedded Systems

  2. Embedded Systems • Products with included processing elements • not general purpose computing platforms • Special purpose computing platforms • System On a Chip (SoC)‏ • microcontrollers • ARM • microprocessors • RISC - PowerPC • INTEL - 808x • Single board computers • PC104 • Mini ITX, Pico ITX

  3. Classifications • Small Scale • use a single 8 or 16 bit microcontroller, no OS, development usually done in C • Medium Scale • usually 1 or 2, 16 or 32 bit microcontrollers, DSPs or RISC processors, a RTOS, usually a suite of development tools • Large scale • many processors, complex connections and dependancies, multiple languages and OSs

  4. Small Scale Examples • Test equipment • Digital volt-ohm meters • Inductance – Capacitance meters • Handheld games and electronic toys (robots)‏ • Cheap cell phones • LCD panel controllers • Higher level electronic components (Blinkm)‏ • Robots (roomba)‏

  5. Medium Scale Examples • High level game platforms (Xbox, PSP, PS2)‏ • Digital Picture Frames • Consumer grade Routers (D-Link, Linksys)‏ • Smartphones • GPS Devices • PDAs • Cameras (still and video)

  6. Software Development • Usually done on a host computer • windows is most common • Linux is also popular • Method • develop (compile, link and build) on host • download into target • test and debug on target or on host based simulator • Toolchains • set of development tools for the target platform • sometimes provided by OEM, sometimes from GNU

  7. Languages • C is most common • since most systems are memory and file system constrained, C++ is too bloated • Jazelle architecture provides native Java • Assembler is a common way of forcing a large program into a small space but only as a last resort • Basic – mostly on PIC microcontrollers
