Modeling languages like the waveform description language WDL are aiming to provide an ideal high-level representation, avoiding limitations by the combination of aspects from different existing languages.

...the observed relation between signal processing code size and control code size, which is actually 2000 lines versus 8000 lines demands for a code generation solution...large parts of the code are very regular and with every change in the partitioning or scheduling, the implementation has to be changed substantially. On the other hand signal processing implementations are highly individual and can hardly be automated by some tool process.
