The document provides information on the Crusoe processor developed by Transmeta Corp. It summarizes that the Crusoe processor is a 128-bit microprocessor designed for mobile devices where low power consumption is required. It operates at 500-700 MHz and uses Transmeta's code morphing software and long run power management technologies. The document outlines the Crusoe processor family, its VLIW hardware architecture, long run power management features, and architecture. It also discusses where Transmeta could expand its applications in the future.

3. INTRODUCTION
• Crusoe processor is 128 bit microprocessor which is build for
mobile computing devices where low power consumption is
required.
• Developed by small silicon valley startup company called
Transmeta Corp.
• Easily understood from simple sketch of the processor
architecture called AMOEBA.
• Processor core operates at 500-700 MHz.

4. CRUSOE PROCESSOR
• Hybrid processor.
• It has a software part and a hardware part with the software
part layer surrounding the hardware unit.
• 128 – bit microprocessor.
• Fabricated on CMOS process.
• Based on technique called VLIW.
 It uses Transmeta’s two patent technologies
• Code morphing software
• Long run power management

5. FEATURES
• Mobile computing devices like laptops , web slates &
notebook PCs are becoming common.
• Heart of every PC is MICROPROCESSOR.
• The mobile computing market has never had a microprocessor
specially designed for it.

6. DRAWBACKS
• Consumes lots of power.
• They get very hot.
• Needs a cooling fan.
• When you are on go, a power hungry processor.
 run out of power before you’ve finished.
 run more slowly and lose application performance.

7. CRUSOE PROCESSOR FAMILY
•TM 5400:-500-700 mhz 256k L2 cache.
•TM 5500:-667-800 mhz 256k L2 cache.
•TM 5600:-500-700 mhz 512k L2 cache.
•TM 5800:-667-800 mhz 512k L2 cache.

8. CRUSOE PROCESSOR VLIW HARDWARE
• Very Long Instruction Word.
• Combines multiple standard instructions into one long
instruction word.
• Explicit parallelism.
• Trace scheduling.
• A Very Long Instruction Word is called a molecule.
• Each molecule contains 4 atoms: one instruction for each FU.
• A molecule is either 128 bits or 64 bits wide.

9. TRANSMETA’S CRUSOE CORE

10. LONG RUN POWER MANAGEMENT
• The TM5600 can adjust its power consumption without
turning itself off.
• It can adjust its clock frequency on the fly.
• It does so quick and without requiring an operating system
reboot or having to go through a slow sequence of suspending
to and restarting from RAM.

11. CRUSOE PROCESSOR ARCHITECHTURE

12. WHERE TRANSMETA COULD GO NEXT
• The current emphasis is on mobile computing.
• Different applications of Code Morphing could be made to
allow a different emphasis or target.
• Optimization techniques could be tailored to different target
architectures.
• Workstation/Server chips were hinted at in the documentation.
