Architecture selection of a flexible DSP core using reconfigurable system software

MetaCore is a flexible DSP core in that the architecture of MetaCore can be modified easily by changing the hardware parameters. To fully exploit the merits of a flexible core, the system software must be re-configurable when the target architecture changes. In this paper, we present a re-configurable system software for a flexible DSP core and the architecture selection procedure called "compile-simulate-refine" cycle using the re-configurable system software. The "compile-simulate-refine" cycle can make it possible to select the best architecture for a given application by exploring the possible candidate architectures in short time.
