Abstract: The analyses of performance versus complexity of all the available algorithms in hardware/software are necessary to study the effectiveness of the implementation in a SoC-based design environment. Several performance-complexity analyses have been conducted, but no standard method has been reported. In this thesis, we propose a Performance-Complexity Index (PCI) to evaluate the cost-effectiveness of implementing one algorithm over other of same type, taking into account trade-offs in performance and complexity. As a demonstration, we analyze the performance and complexity of the two contending entropy coders adopted by H.264/AVC: Context-based Adaptive Binary Arithmetic Coding (CABAC) and Context-based Adaptive Variable Length Coding (CAVLC). Empirical test results using standard sequences show that it is more cost-effective to use CABAC for encoding when the Rate-Distortion Optimization mode is turned off regardless of configurations, in both variable and constant bit-rate implementations. The conclusions based on PCIs are also in total agreement with the empirical results.
