Sammanfattning
In this project, we attempt to implement a decoder for the MPEG-1 video standard
using Feldspar, an embedded domain specific language in Haskell. The idea is
to evaluate whether Feldspar is suitable for more advanced DSP applications and
whether it can result in simpler code compared to a lower level language like C while
maintaining similar performance. We succeed in implementing a functioning, albeit
limited and slow decoder which shows that Feldspar is capable of such a task. We
discover that some parts of the implementation are simpler compared to a low level
language while others are similar, if not more complicated. We also discuss the pros
and cons of Feldspar and suggest improvements that could be made to the language.
