A transformational approach to VHDL and CDFG based high-level synthesis: a case study

In this paper, a novel multi-target design methodology based on the concepts of transformational design, and its application to the interlaced-to-progressive scan conversion (IPSC) problem, are discussed. Starting from a single high-level behavioral specification in VHDL a direction detector used in IPSC algorithms is mapped onto both a custom implementation and a programmable video signal processor. Results are compared with those previously obtained using different tools and methodologies.
