Résumé: In this paper we study the computational complexity of the intra/inter prediction modules for video coding software according to H.264/AVC standard. We analyse separately the complexity of each mode toward an implementation on TMS320C64 platform. Since any real-time implementation is considered to be time and money consuming, complexity pre-analysis of any giving video-coding algorithm is very important to determine not only software bottlenecks, but also the minimum hardware resources and characteristics required for the targeted platform. To estimate the total complexity of the prediction processes (intra/inter), we assume that the encoder tests all modes. The total cycle’s account is estimated by multiplying the number of cycles of each mode by the number of macroblocks in the frame. Simulation results indicate that our methodology for the complexity analyses for H.264/AVC prediction modules provides a good approximation with respect to the experimental results.
