Developing a Retargetable Compiler: Some Preliminary Results

The current paper reports on the first results of building a retargetable compiler for reconfigurable computing. The discussed research is part of a larger project whose main objective is to develop a semi-automatic tool platform for reconfigurable computing supporting a fully integrated design environment. It constitutes the first attempt to provide a workbench that will cover the entire design trajectory of general-purpose augmented processors with reconfigurable computing parts. The scope of the proposed platform regards processors that intend to speed-up single program execution using reconfigurable hardware. Consequently, the Delft Workbench platform targets architectures with single program counters (uni-processors) incorporating reconfigurable co-processing. Based on a particular architectural paradigm we use a SET / EXECUTE function scheduling platform and we provide appropriate modifications to the compiler back-end so that the SET / EXECUTE can be incorporated. Keywords—retargetable compiler, reconfigurable system, IR extension.
