Abstract - Data transfers and storage are crucial cost factors in multi - media systems Systematic methodologies are needed to obtain dramatic reductions in terms of power, area and cycle count Upcoming multi - media processing applications will require high memory bandwidth In this pa - per, we estimate that a software reference implementation of an MPEG - video encoder typically requires Gtransfers s to main memory for a sim - ple profile level L2 This shows a clear need for optimization and the use of intermediate memory stages By applying our ACROPOLIS methodology, developed mainly to relieve this data access bottleneck, we have arrived at an implementation which needs a factor 65 less background accesses In addition, we also show that we can heavily improve on the memory trans - fers, without sacrificing speed (even gaining about 10% on cache misses and cycles for a DEC Alpha), by aggressive source code transformations |
