A high performance and low power hardware architecture for the transform & quantization stages in H.264
Owaida, M.; Koziri, M.; Katsavounidis, I.; Stamoulis, G. (2009)In this work, we present a hardware architecture prototype for the various types of transforms and the accompanying quantization, supported in H.264 baseline profile video encoding standard. The proposed architecture ... -
Implementation of the AVS video decoder on a heterogeneous dual-core SIMD processor
Koziri, M.; Bellas, N.; Katsavounidis, I.; Zacharis, D. (2010)This paper presents the implementation of Advanced Audio and Video Standard Part 2: Video (AVS P2), the Chinese video standard, to Diamond 388VDO Video Processor, a heterogeneous dual core Tensilica SIMD processor. Through ... -
Implementation of the AVS Video Decoder on a Heterogeneous Dual-Core SIMD Processor
Koziri, M.; Zacharis, D.; Katsavounidis, I.; Bellas, N. (2011)Multi-core Application Specific Instruction Processors (ASIPs) are increasingly used in multimedia applications due to their high performance and programmability. Nonetheless, their efficient use requires extensive ... -
Joint quantizer optimization for scalable coding
Koziri, M.; Eleftheriadis, A. (2010)Scalability is an attractive solution to the problems posed by modern multimedia transmission systems. The key for better performance in scalable coding is joint rate distortion optimization. We present a new stochastic ... -
A low-power VLSI architecture for intra prediction in H.264
Stamoulis, G.; Koziri, M.; Katsavounidis, I.; Bellas, N. (2005)The H.264 video coding standard can achieve considerably higher coding efficiency than previous standards. The key to this high code efficiency are mainly the Intra and Inter prediction modes provided by the standard. ... -
