Subword permutation instructions for two-dimensional multimedia processing in MicroSIMD architectures
Proceedings IEEE International Conference on Application-Specific Systems, Architectures, and Processors
MicroSIMD architectures incorporating subword parallelism are very efficient for application-specific media processors as well as for fast multimedia information processing in general-purpose processors. This paper addresses the unsolved problem of the need to permute the subwords packed in registers for maximum parallelism performance, especially for two-dimensional (2-D) multimedia algorithms. We propose a new systematic approach for identifying the fundamental data rearrangement needs indoi:10.1109/asap.2000.862373 dblp:conf/asap/Lee00 fatcat:4obc7vz5pzcdddrjildnepdp5m
