MICROCONTROLLERS AND EMBEDDED PROCESSORS

DESKTOP Vs EMBEDDED

INTRODUCTION

EVOLUTION OF EMBEDDED MICROPROCESSORThe 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

32- BIT EMBEDDED PROCESSORS

Intel’s i960

Motorola’s Coldfire,

Sun’s Sparc,

Hitachi’s SuperH

Advanced RISC Machines’ ARM,

FIELD OF APPLICATIONS

•Video game consoles•Handheld palmtop•Automobile •Cellular phones •Mobile Sets•Set-top boxes and DVD •Digital cameras

CLASSES OF EMBEDDED PROCESSORS

FEATURES OF EMBEDDED PROCESSORS

Reducing power consumption PerformanceCode densityPeripherals and higher integration Multimedia acceleration

HARDWARE REFERENCE MODEL

•Purpose processor•Power harvesting subsystem•Wireless transceiver •50K RAM.

PROGRAMMING MODELSelf-Assembling Code

Memory Allocation

PROGRAMMING MODEL (Coutd..)

Code Segments

Run-Time Scheduling

STANDARD OPERATING SYSTEMS

WINDOWS CE

Microsoft’s new operating system standardized for handheld and palmtop PCs, personal communicators, Internet phones, video game consoles etc

With Java, developers can write code for a specific system independently of the underlying processor platform.

MOTOROLA COLDFIRE PROCESSORS

Variable-length (VL)32-bit RISC instruction setPrefetch pipelineBranch prediction capabilitiesHigher frequencies of operationCode Compatibility

The ArchitectureThe Pipelined Approach Block Diagram

ADVANCED CONCEPTS USING EMBEDDED PROCESSORS

Multithreaded Embedded microprocessor

•Multi Threading•The Architecture•Performance enhancement

Self-Optimizing Embedded Microprocessor

•Optimization•Loop Table•Execution

Multimedia Processor

•Configuration•Advanced Cache•Performance

CONCLUSION

The Demand for the compact Devices is GrowingLow cost and high utility processors with advanced multimedia, multithreading and other concepts are getting easily availableManufacturers are Producing More efficient embedded ProcessorsThe market is moving towards a bright future
