公開日期: | 2001 | 卷: | 2 | 起(迄)頁: | 193 - 196 | 來源出版物: | ISCAS 2001 - 2001 IEEE International Symposium on Circuits and Systems, Conference Proceedings | 會議論文: | 2001 IEEE International Symposium on Circuits and Systems, ISCAS 2001 | 摘要: | This paper presents a hardware-efficient architecture of tree-depth scanning (TDS) and multiple-quantization (MQ) scheme for MPEC-4 still texture coding. By means of the novel architecture, the TDS can achieve its maximal throughput to area ratio and minimal external memory access with only one wavelet-tree size on-chip memory. Besides, MQ adopts the proposed POT (power of 2) quantization, which is proved to have very similar performance to generic (user-defined coefficients) scalar quantization, to achieve the most cost-effective hardware implementation. The prototyping chip has been implemented in a TSMC 0.35 /spl mu/m CMOS technology. This architecture can handle 30 4-CIF frames per second with 5 spatial layers and 3 SNR layers scalability at 100 MHz clock frequency. © 2001 IEEE. |
