  1. 1. Crusoe Processor Presented by Shreevijay Ittannavar 27/10/2010 CET DIGITAL SIGNAL PROCESSING
  2. 2. Session Plan <ul><li>Introduction </li></ul><ul><li>Aim </li></ul><ul><li>About technology </li></ul><ul><li>Technical issues </li></ul><ul><li>Applications </li></ul><ul><li>Conclusion </li></ul><ul><li>References </li></ul>27/10/2010 2 CET DIGITAL SIGNAL PROCESSING
  3. 3. Introduction <ul><li>A low power consuming x86 processor. </li></ul><ul><li>Developed by Transmeta Corporation. </li></ul><ul><li>Devoted to fill gap in mobile CPU market. </li></ul><ul><li>Hybrid hardware-software design. </li></ul><ul><li>In Jan. of 2000, Transmeta Corp. introduced the Crusoe processors. </li></ul><ul><ul><li>Remarkably low power consumption. </li></ul></ul><ul><li>As might not be expected, The new technology is fundamentally software-based. </li></ul><ul><ul><li>The power savings come from replacing large numbers of transistors with software . </li></ul></ul>27/10/2010 3 CET DIGITAL SIGNAL PROCESSING
  4. 4. Aim <ul><li>Brief points About Crusoe Processor </li></ul><ul><ul><li>Transmeta Takes Aim at Mobile Devices. </li></ul></ul><ul><ul><li>Low power consumption. </li></ul></ul><ul><ul><li>The highest-performance Crusoe chip, the TM5400 </li></ul></ul>27/10/2010 4 CET DIGITAL SIGNAL PROCESSING
  5. 5. About Technology <ul><li>Architecture: </li></ul><ul><li>Consists of a hardware engine logically surrounded by a software layer. </li></ul><ul><ul><li>H/W: The engine </li></ul></ul><ul><ul><ul><li>is a VLIW CPU capable of executing up to four operations in each clock cycle. </li></ul></ul></ul><ul><ul><ul><li>No resemblance to the x86 instruction set. </li></ul></ul></ul><ul><ul><li>S/W: Code Morphing Software( CMS ) </li></ul></ul><ul><ul><ul><li>Dynamically “ morphs ” x86 instructions into VLIW instructions </li></ul></ul></ul>27/10/2010 5 CET DIGITAL SIGNAL PROCESSING
  6. 6. About Technology Contd.. <ul><li>Five execution units; two arithmetic-logic, a load/store, a branch, and a floating-point. </li></ul><ul><li>Can execute four instructions in a cycle. </li></ul><ul><li>Sixty-four general-purpose and 32 floating-point working registers shadowed by 48 general-purpose and 16 floating-point registers. </li></ul><ul><li>64KB level one (L1) caches and a 256KB level two (L2) cache. </li></ul>27/10/2010 6 CET DIGITAL SIGNAL PROCESSING
  7. 7. About Technology Contd.. <ul><ul><li>Each new CPU design only requires a new version of the Code Morphing software to translate x86 instructions to the new CPU’s native instruction set. </li></ul></ul>27/10/2010 7 CET DIGITAL SIGNAL PROCESSING
  8. 8. About Technology Contd.. <ul><li>Crusoe Features </li></ul><ul><li>Dynamic binary translation, gives programs the impression that they are running on an x86 machine. </li></ul><ul><li>VLIW processor executes up to 4 instructions in parallel. </li></ul><ul><li>LongRun power control adjust CPU power to the tasks being performed. </li></ul><ul><li>If you have fewer transistors, you burn less power. </li></ul><ul><li>Only those functional units that are absolutely needed to execute an instruction are turned on. </li></ul>27/10/2010 8 CET DIGITAL SIGNAL PROCESSING
  9. 9. Technical Issues <ul><li>Crusoe Processor does not have- </li></ul><ul><li>no superscalar decode, grouping, or issue logic. </li></ul><ul><li>no register renaming. </li></ul><ul><li>no segmentation hardware. </li></ul><ul><li>no floating-point stack hardware. </li></ul><ul><li>less interlock and bypassing logic than a traditional central processing unit. </li></ul>27/10/2010 9 CET DIGITAL SIGNAL PROCESSING
  10. 10. Applications <ul><li>Notebook: Sony, others. </li></ul><ul><li>Compact Servers: RLX technologies. </li></ul><ul><li>Transmeta Crusoe and Crusoe SE processors are designed for embedded applications in the areas of offi ce automation, networking/communications, storage, server-based computing, science and medicine and industrial automation. </li></ul><ul><li>The Transmeta Crusoe processor is ideal for applications that require high performance processing within small and thermally constrained environments. </li></ul>27/10/2010 10 CET DIGITAL SIGNAL PROCESSING
  11. 11. Conclusions <ul><li>Great choice for mobile computing. </li></ul><ul><li>Great choice for systems where low power processing is required. </li></ul><ul><li>Revolutionary hybrid design. </li></ul><ul><li>Efficient use of instruction optimization. </li></ul><ul><li>Leads the path in efficient computing. </li></ul>27/10/2010 11 CET DIGITAL SIGNAL PROCESSING
