Different applications exhibit different behavior that cannot be optimally captured by a fixed organization of a VLIW processor. However, through exploitation of reconfigurable hardware the authors can optimize the organization when running different applications. In this paper, they propose a novel way to execute the same binary on different issue-width processors without much hardware modifications. They propose to change the compiler and assembler to ensure correct results. Their experiments show an average slowdown of around 1:3 when compared to binaries compiled for specific issue-widths.
