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...
In order to address the throughput constraints of the system at minimal power consumption, the workload of computing nodes should be balanced. This requires accounting for the underlying hardware characteristics and throughput sustainable by these nodes. This work provides a workload distribution and balancing methodology of a divisible load under a throughput constraint, on heterogeneous nodes. The...
This paper presents a cross-layer approach for analyzing and designing energy-efficient advanced multimedia systems with next-generation High-Efficiency Video Coding (HEVC) standard. Our approach leverages both algorithmic and architectural layers of system design abstractions in order to achieve a high power/energy efficiency. We present an analysis and design of an HEVC-based multimedia system while...
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...
