Abstract: The Compaan/Laura tool chain allows efficient mapping of signal processing applications written in Matlab onto reconfigurable platforms. In this chain, the Matlab code is converted into a Kahn Process Network model, which serves as input to a hardware generation tool. An important issue in this hardware generation tool is the realisation of control in hardware. Since this control is based on parametrised polytopes, its mapping to hardware is not straightforward. In this paper, we present different strategies for mapping this control to hardware, and explore the trade off between speed and resource usage.

Keywords: parameterised control; hardware synthesis; loop parallelisation; Kahn process networks; KPN; signal processing; reconfigurable platforms; hardware generation; control mapping; speed; resource usage.
