| Abstract: | In this paper, we present a performance analysis for an MPEG‐4 video codec based on the on‐chip network communication architecture. The existing on‐chip buses of system‐on‐a‐chip (SoC) have some limitation on data traffic bandwidth since a large number of silicon IPs share the bus. An on‐chip network is introduced to solve the problem of on‐chip buses, in which the concept of a computer network is applied to the communication architecture of SoC. We compared the performance of the MPEG‐4 video codec based on the on‐chip network and Advanced Micro‐controller Bus Architecture (AMBA) on‐chip bus. Experimental results show that the performance of the MPEG‐4 video codec based on the on‐chip network is improved over 50% compared to the design based on a multi‐layer AMBA bus. |
