This technique is used wherever there is a possibility for data dependencies.
2.
Instructions can be grouped together only if there is no data dependency between them.
3.
A major obstacle for vectorization is true data dependency shorter than the vector length.
4.
The logical complexity of dynamically keeping track of the data dependencies, restricts " OOE"
5.
This is accomplished in CPUs that dynamically tag the data dependencies of the code in the execution window.
6.
It allows for multiple instructions to be dispatched at once regardless of the data dependencies between those instructions.
7.
This information can enable compiler optimizations, in particular loop nest optimization, and parallelization through data dependency analysis.
8.
For example, multiplying two matrices can be processed by concurrent threads on a GPGPU device without any output data dependency.
9.
There are different kind of parallelization techniques which are used on the basis of data storage overhead, degree of parallelization and data dependencies.
10.
The 6x86 is superscalar and superpipelined and performs register renaming, speculative execution, out-of-order execution, and data dependency removal.
