Dynamic Parallel Media Processing Using Speculative Broadcast Loop (SBL) (Extended Abstract)

By Jason Fritts and Wayne Wolf


This paper presents the results of a study of dynamic parallel media processing using Speculative Broadcast Loop (SBL), a speculative run-time loop-level parallelization method. Due to processing regularity, multimedia applications typically contain extensive parallelism. Data parallelism between independent loop iterations may be supported by subword parallelism methods, but much of the data parallelism is of a larger granularity that may not be effectively supported with subword parallelism. Larger-scale parallel processing methods are needed to support the full range of data parallelism in multimedia. Because static parallel compilation methods are often unable to recognize all parallelism at compile time, a run-time method is ass..
