Design approaches for MPEG engines for broadband and mobile applications

This paper presents recent advances in MPEG-2/4 audio and video (AV) codec implementations for broadband and mobile applications. Several design approaches based on special purpose hardwired LSIs, programmable DSPs, media processors, embedded MPUs, and MPUs for personal computers (PCs), which are used to implement MPEG engines are introduced. Then, design approaches for low power and low cost AV codec LSIs for broadband and mobile applications are discussed, by introducing recent implementation examples. Finally, future trends and challenges are discussed.
