Design of System Bus Interface and Inter-connection of SoC-Based CABAC Encoder

Abstract

As introduced in Chap. 4 one step of the SoC-based entropy coder design flow is SoC features introduction. Design of system bus interface for the CABAC encoder enhances portability and reusability of the design in the SoC video encoder system. In this chapter, design of master and slave interfaces of WISHBONE Wishbone system bus of CABAC encoder is discussed after the introduction of WISHBONE system bus specifications. The crossbar system bus inter-connection is also designed, which enables convenient integration of the proposed CABAC encoder with other IP blocks in the H.264/AVC encoding system.
