Abstract
the HEVC is a proposal of new video coding standard that will be used for a wide range of applications like ULTRA-HD and 3D applications. MPEG and VCEG have established a Joint Collaborative Team on Video Coding (JCT-VC) to develop the HEVC (High Efficiency Video Coding) standard which is expected to provide a significant improvement in data transmission and streaming efficiency compared to H. 264. In this proposal standard, various modules of coding are defined. Among the most complex is the module of the intra prediction. The HEVC defines 35 modes of intra prediction for 8x8, 16x16, 32x32, 3 modes for 64x64 and 17 modes for 4x4 while the H. 264/AVC (Advanced Video Coding) uses 9 modes for intra-4x4 and 4 modes for intra-16x16. In this paper, we propose an efficient uniform architecture for all of the 4x4 intra directional modes. This architecture offers an important gain in case of treatment time compared to the literature. Our proposed architecture is implemented with the technology TSMC 0.18 mu m CMOS.
