What is Proceedings of the eleventh ACM international conference on Multimedia - MULTIMEDIA '03 - Programming portable optimized multimedia applications about?

Multimedia computer architectures can speed-up applications significantly when programmed manually. Optimized programs have been non-portable up to now, because of differences in instruction sets, register lengths, alignment requirements and programming styles. We solve all these problems by using a library of C pre-processor macros called MMM. We implemented three examples from video compression in MMM, and automatically translated them into optimized code for four distinct multimedia processors. Their performance is comparable, and in several cases better, than equivalent examples optimized by the processor vendors.
