It is particularly true in the field video compression. However at each improvement in efficiency and functionality the complexity of the algorithms is also increasing. Textual specifications that in the past were the original form of specifications have been substituted by reference software which became the starting point of any design flow leading to implementation. Therefore designing an embedded application has become equivalent to port a generic software on a possibly heterogeneous embedded platform. Such operation is getting more and more difficult because of the increased algorithm complexity and the wide range of architectural solutions. This paper describes a new platform aiming at supporting a step-by-step mapping of reference software . generic and nonoptimized software into software and hardware implementations. The platform provides a seamless interface between the software and hardware environments with profiling capabilities for the analysis of data transfers between hardware and software. Such profiling capabilities help the designer to achieve different implementations aiming at specific objectives such .
