Hierarchical Interface Design Methodology: Using Real-Time MP3 codec as a case

Abstract

In this paper a method for rapidly SoC IP interface design called hierarchical interface design method and models is proposed. The method is an interface design scheme that can be used to integrate different IPs easily. The main concept is to design IP and its interface separately. It introduces a virtual interface concept to simplify interface design. To verify the practicability, we use the hierarchical interface design model to implementation a real-time MP3 codec system. Finally a software /hardware co-simulation is done to verify the entire MP3 real-time codec system. Experiments show that the hierarchical interface design me thodology results in minor hardware overhead on the original design. Different IPs can integrate in this scheme to reduce time to market.
