The needs for automated digital system design rise with constant technology improvements and time-to-market shortening. High-level synthesis tools cope with this problem by raising the design specification to a higher level. We have implemented the methodology of custom processor automated modeling for DCT algorithm. This algorithm is often used in signal and image processing applications. At front end, the methodology assumes C code input specification as it is the case of many high-level synthesis tools. C programming language popularity offers the applicability for a broader spectrum of users. At back end, logic synthesis tools produce the FPGA implementation of the algorithm. The results are evaluated in terms of execution cycles required for completing the algorithm and processor's datapath components allocations, and compared to previous work.
