A Preliminary Study on the Vectorization of Multimedia Applications for Multimedia Extensions [chapter]

Gang Ren, Peng Wu, David Padua
2004 Lecture Notes in Computer Science  
Based on a code study of the Berkeley Multimedia Workload, we identify several new challenges arise in vectorizing for multimedia extensions, and provide some solutions to these challenges.  ...  Because of the similarity between multimedia extensions and vector processors, it is believed that traditional vectorization can be used to compile multimedia extensions.  ...  Our study showed that despite the success of vectorizing for traditional vector processors, the vectorization for multimedia extensions still has a long way to go.  ...

MOM is a novel matrix-oriented ISA paradigm for multimedia applications, based on fusing conventional vector ISAs with SIMD ISAs such as MMX.  ...  This paper justifies why MOM is a suitable alternative for the multimedia domain due to its efficiency handling the small matrix structures typically found in most multimedia kernels.  ...  Therefore, as a preliminary study, this paper is going to concentrate mostly on kernels, because it is easier to understand the performance gains of MOM on these shorter sequences of code.  ...
