This paper presents a fault-tolerance technique for H.264's Context-Adaptive Variable Length Coding (CAVLC) on unreliable computing hardware. The application-specific knowledge is leveraged at both algorithm and architecture levels to protect the CAVLC process (especially context adaptation and coding tables) in a reliable yet power-efficient manner. Specifically, the statistical analysis of coding...
Advancement in technology has complemented the increased complexity of state-of-the-art video coding standards by providing high-performance multimedia platforms. This has resulted in non-negligible computational reliability issues, especially with respect to soft errors. This paper motivates the dire need towards computationally Reliable Video Coding (ReVC) on modern hardware platforms. We highlight...
This paper presents a high-throughput hardware architecture for H.264/AVC CAVLC encoding. Our scheme eliminates the pipeline stage of computing the coefficient statistics (as adopted by state-of-the-art hardware architectures) with a pre-processing stage during the quantization in order to avoid the extra looping logic in CAVLC. This provides significant performance improvement compared to state-of-the-art...
