boosting performance. Overall, DIB architecture offers up to three times the

bandwidth performance over a single-bus architecture processor.

Advantages of DIB

1.Faster cache Access

2.Improves Band Width

3.Bot busses are accessed simultaneously hence through put is improved

4.Allow Multiple simultaneous cache request.

Hyper Threading – Intel Proprietary

Intel’s HT Technology allows a single processor or processor core to handle two

independent sets of instructions at the same time. In essence, HT Technology converts a

single physical processor core into two virtual processors.

The point of hyper threading is that many times when you are executing code in the

processor, there are parts of the processor that is idle. By including an extra set of CPU

registers, the processor can act like it has two cores and thus use all parts of the

processor in parallel. When the 2 cores both need to use one component of the

processor, then one core ends up waiting of course. This is why it can not replace dual-

core and such processors.

Hyper-Threading is a technology used by some Intel microprocessor s that

allows a single microprocessor to act like two separate processors to the operating

system and the application program s that use it. It is a feature of Intel's IA-

32 processor architecture.
