  1. ADVANCED EMBEDDED MICROPROCESSORS AND APPLICATIONS Submitted by Amit Kumar Sahoo Under the guidance of Mr. M. Suresh

  2. INTRODUCTION • MICROCONTROLLERS AND EMBEDDED PROCESSORS • DESKTOP Vs EMBEDDED

  3. EVOLUTION OF EMBEDDED MICROPROCESSOR • The 1980s • RISC was introduced • Early 1990s • RISC versus CISC • Power consumption, code density, and integration • Late 1990s • 32-bit embedded processors • Java and Windows CE • After 2000 • Multimedia and DSP • Multithreading

  4. 32- BIT EMBEDDED PROCESSORS • Intel’s i960 • Motorola’s Coldfire, • Sun’s Sparc, • Hitachi’s SuperH • Advanced RISC Machines’ ARM,

  5. FIELD OF APPLICATIONS • Video game consoles • Handheld palmtop • Automobile • Cellular phones • Mobile Sets • Set-top boxes and DVD • Digital cameras

  6. CLASSES OF EMBEDDED PROCESSORS

  7. FEATURES OF EMBEDDED PROCESSORS • Reducing power consumption • Performance • Code density • Peripherals and higher integration • Multimedia acceleration

  8. HARDWARE REFERENCE MODEL • Purpose processor • Power harvesting • subsystem • Wireless transceiver • 50K RAM.

  9. PROGRAMMING MODEL • Self-Assembling Code • Memory Allocation

  10. PROGRAMMING MODEL (Coutd..) • Code Segments • Run-TimeScheduling

  11. STANDARD OPERATING SYSTEMS • WINDOWS CE • Microsoft’s new operating system standardized for handheld and palmtop PCs, personal communicators, Internet phones, video game consoles etc • JAVA • With Java, developers can write code for a specific system independently of the underlying processor platform.

  12. MOTOROLA COLDFIRE PROCESSORS • Variable-length (VL) • 32-bit RISC instruction set • Prefetch pipeline • Branch prediction capabilities • Higher frequencies of operation • Code Compatibility

  13. The Architecture The Pipelined Approach Block Diagram

  14. ADVANCED CONCEPTS USING EMBEDDED PROCESSORS • Multithreaded Embedded microprocessor • Multi Threading • The Architecture • Performance enhancement
