Hardware Synthesis of A Parallel JPEG Decoder from Its Functional Specification
[chapter]
IFIP International Federation for Information Processing
Preserved Fulltext
Starting with a clear, intuitively correct specification of the problem, in a functional language such as Haskell, we apply a set of formal transformation laws to refine it into a behavioural definition ...
We apply this technique to a non-trivial, real world problem -a JPEG decompression algorithm, and achieve a truly scalable, parallel hardware implementation. ...
We have illustrated this with the development of a JPEG decoding algorithm, starting from a high level and intuitive specification in Haskell, and using this to derive a parallel Handel-C program that ...
