    The idea of aliasing frequently with respect to some of the speculative techniques is known. Give two examples of aliasing and explain how aliasing can impact performance of a pipeline?

    Aliasing is explained with examples from computing and signal processing domains.

    Aliasing is widely used in signal processing and it related disciplines and also in computing.

    In signal processing, aliasing refers to an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled.

    Aliasing that occurs in signals sampled in time, for instance digital audio, and is referred to as temporal aliasing.

    Aliasing that occurs in spatially sampled signals, for instance digital images. Aliasing in spatially sampled signals is called spatial aliasing.

    In computing, aliasing describes a situation in which a data location in memory can be accessed through different symbolic names (called aliases) in the program. Thus, modifying the data through one name implicitly modifies the values associated with all aliased names, which may not be expected by the programmer. So this has to be handled carefully.

    Aliasing has significant impact in processing a pipeline. If operations in a pipeline are referring to aliased memory locations, then they need to be carefully evaluated and it might slowdown processing of the pipeline significantly. Aliasing would have lot of impact when processing iterations.
