Formal datapath representation and manipulation for implementing DSP transforms
Peter A. Milder, Franz Franchetti, James C. Hoe, Markus Püschel · 2008
We present a domain-specific approach to representing datapaths for hardware implementations of linear signal transform algorithms. We extend the tensor structure for describing linear transform algorithms, adding the ability to explicitly characterize two important dimensions of datapath architecture. This representation allows both algorithm and datapath to be specified within a single formula and gives the designer the ability to easily consider a wide space of possible datapaths at a high level of abstraction.
