Abstract

HW/SW-codesign has been applied to a wide range of applications. Several partitioning methods have been suggested. Thus the designer selects modules for HW or SW-implementation for the best possible performance within a set of performance and design constraints. This paper describes an estimation method to approximate a priori the entire system performance. The estimation method has been integrated into the codesign tool COD and first results could be generated. The estimated speed-up has been determined for a ciphering algorithm and has been compared to the speed-up of the entire HW/SW-system. The estimation speed-up matches the final speedup.
