Implementation of a H.264/AVC SVC decoder with multi-symbol prediction CAVLC for advanced T-DMB receiver
This paper presents a low-cost high-performance H.264/AVC SVC decoder with multi-symbol prediction context-based adaptive variable length coding (CAVLC) for advanced T-DMB receiver. Proposed multi-symbol prediction CAVLC mainly consists of a simple arithmetic operation unit with reduced look-up tabl...

description | This paper presents a low-cost high-performance H.264/AVC SVC decoder with multi-symbol prediction context-based adaptive variable length coding (CAVLC) for advanced T-DMB receiver. Proposed multi-symbol prediction CAVLC mainly consists of a simple arithmetic operation unit with reduced look-up tables and a leading zero detector. We also propose a multi-symbol run_before decoder and it decodes more than 2.5 symbols in a cycle. Gate count of a H.264/AVC SVC decoder is about 1,300K gates when synthesized with 0.18 um CMOS process and it can be operated at 120 MHz clock frequency. For the verification of a H.264/AVC SVC decoder chip, prototype mobile movie player systems have been implemented using a 7 inch LCD and USB controller. |
