Hyper threading technology

  1. 1. Rahul soni Department of EIC 8th Sem 1
  2. 2. 1.Introduction 2.What is hyper-threading. 3.How Hyper-threading work. 4.Architecture 5.Implementation on Intel xeon Processor 6.Media Application 7.Conclusion 8.References 2
  3. 3.  Ground breaking technology from the intel that allows processor to work more efficiently.  Technology enables the processor to execute series of instruction allows at the same time.  Improved the onboard so that the second thread can be processed in the same processor.  Hyper-threading provides two logical processor in a single logical processor. 3
  4. 4.  Is a technique used to improve parallelization of computations performed on PC microprocessor.  Is a technique which enables single CPU to act like multiple CPU’s.  Enables different parts of the CPU to work on different tasks concurrently.  Threaded software application to execute threads in parallel in a single multi-core processor instead of thread processing in linear fashion. 4
  5. 5.  Hyper-threading technology takes advantage of multithreading capability.  Processor use the resources otherwise would sit idle and done more work in same amount time.  Divide the workload into processes and threads  Execute the threads on different processors. 5
  6. 6. i 6
  7. 7. 7
  8. 8.  Processor without hyper-threading.  Processor with hyper-threading. 8
  9. 9. 9
  10. 10. 10
  11. 11. 11
  12. 12.  Goal of implementation.  Single task and multitask mode.  Operating system and application. 12
  13. 13. 13
  14. 14.  Is to better explain the performance improved that are possible in multimedia application using hyper-threading technology.  Multimedia workloads.  MPEG decode and encoder.  Video watermarking  Task partitioning and scheduling methods. 14
  15. 15. 1.Data-domain decomposition slice-based- dispatching. 2.Function decomposition of video watermark detection. 15
  16. 16.  Intel Xeon Hyper-Threading is definitely having a positive impact on Linux kernel and multithreaded applications.  Today with Hyper-Threading Technology, processor-level threading can be utilized which offers more efficient use of processor resources for greater parallelism and improved performance on today's multi-threaded software. 16
