IMPLEMENTING HYPER-THREADING

o Caches: trace cache, L1, L2, L3 o Microarchitectural registers o Execution Units

Shared

o Re-order buffers (ROBs) o Load/Store buffers o Various queues, like the scheduling queues, uop queue, etc.

Partitioned

Register renaming logic Instruction Pointer ITLB Return stack predictor Various other architectural registers

Replicated

Cont.

Replicated Resources

Partitioned resources

Statically Partitioned Queue

Cont.

Dynamically Partitioned Queue

Caching and SMT

Cache conflicts

BIOS SUPPORT

Logical processor startup sequence

HT enable/disable

PERFORMANCE

HYPER THREADING VS DUAL CORE

Cont.

• OPERATING SYSTEM SUPPORT Windows 98 Windows 2000 Windows XP

• OPERATING SYSTEM SUPPORT

• System Requirements

A processor that supports HT Technology HT Technology enabled chipset HT Technology enabled system BIOS HT Technology enabled/optimized operating system

Intel® processors and chipsets support HT Technology:

1066 MHz system bus: 3.73 GHz, 3.46 GHz

800 MHz system bus: 3.80 GHz, 3.60 GHz

1066 MHz system bus: 3.73 GHz, 3.20 GHz

533 MHz system bus: 3.46 GHz, 3.33 GHz, 3.20 GHz, 3.06 GHz, 2.80 GHz

Future

CONCLUSION

The Performance of Computer System will be Increase

With More Economical Price With Least Addition in Power consumption Performance Vs Cost ratio is high
