Abstract

The authors discuss the performance of multiprocessor architectures to be applied for video coding algorithms. SIMD, SIMD cluster, and MIMD architectures are studied by a unified performance approach under specific constraints of video coding algorithms. The proposed performance model considers communication and computation times as well as the required silicon area. MIMD architectures are compared to SIMD with regard to their performance. The optimization of architectural parameters for SIMD and MIMD architectures is discussed. It is shown how the proposed performance model can be applied to the design of VLSI-based multiprocessor systems for video coding
