Abstract

The design of a heterogeneous network-on-chip (NoC) based H.264 video decoder is proposed. A thorough investigation using a system simulator developed as the combination of a cycle accurate NoC simulator together with complete implementations of all the video decoder modules is presented. The target hardware platform is a multicore system-on-chip, where the cores were designed for specific functions that correspond to the modules of the video decoder. Because such cores have different sizes and aspect ratios, a heterogeneous NoC is employed to facilitate the communication between modules. This is different from the reference case of a homogeneous NoC based hardware platform, where all cores are general purpose processors with the same area and where the NoC is a regular mesh NoC. The investigation looks at the impact of core sizes and floorplan for a given technology node as well as at the performance variation across several technology nodes.
