  1. 1. Deepak Ku. Marndi Department of Information & Technology Regd.No- 0801106165 6th SemName-Deepak Ku. Mar ndi Regd.No-0801106165 1
  2. 2. 1.Introduction2.What is hyper-threading.3.How Hyper-threading work.4.Architecture5.Implementation on Intel xeon Processor6.Media Application7.Conclusion8.References Name-Deepak Ku. Marndi Regd.No-0801106165 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 Name-Deepak Ku. Marndi Regd.No-
  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. Name-Deepak Ku. Marndi Regd.No-0801106165 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.

  14. 14.  Isto 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. Name-Deepak Ku. Marndi Regd.No-0801106165 14
  15. 15. 1.Data-domain decomposition slice-based- dispatching.2.Function decomposition of video watermark detection. Name-Deepak Ku. Marndi Regd.No-0801106165 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 todays multi-threaded software. 16 Name-Deepak Ku.
