Reducing Data-Memory Footprint of Multimedia Applications by Delay Redistribution

Balaji Raman, Samarjit Chakraborty, Wei Tsang Ooi, Santanu Dutta
2007 Proceedings - Design Automation Conference  
We show that this delay redistribution technique can signficantly reduce (up to 70%) the total on-chip memory required.  ...  In this paper, instead of associating the playout delay solely with the output device, we propose to redistribute this delay among all the processing elements running the various tasks of the multimedia  ...  The execution of some tasks of multimedia applications (e.g. VLD in MPEG-2) show high data-dependent variability.  ...

External memory page remapping for embedded multimedia systems

Ke Ning, David Kaeli
2007 SIGPLAN notices  
Our approach was developed by studying common data access patterns present in embedded multimedia applications.  ...  Our algorithm can significantly reduce the memory page miss rate by 70-80% on average. For a 4-bank SDRAM memory system, we reduced external memory access time by 12.6% .  ...  In many embedded multimedia applications, execution is dominated by loop bodies that cycle through arrays or matrices of data elements.  ...

2008 ACM Transactions on Design Automation of Electronic Systems  
We evaluate the potential of migrating running tasks between processors to improve performance in a multimedia cell phone example.  ...  In our example, we show that system response time can be improved by as much as 1.96 times when a preemptive migratory scheduler is used, despite the overhead incurred by scheduling tasks across multiple  ...  We note that, like many embedded applications, the tasks in our system do not allocate significant amounts of memory; task state is roughly equivalent to the tasks's input data set.  ...
