Publication Summary
In order to take full advantage of the multicore architecture and improve the encoding performance on multicore processors, we propose a dynamic workload partition mechnisam to adaptively adjust the size of the strips. The video strips can be efficiently partition to the several cores. The encoding side information such as the bits consumption, the MB type statistic information or the encoding time on each core can send to the main processor to make a wise strips partition.| Country | |

Dynamic Workload Partition Mechanism for videocoding on Multicore platform
For the video encoding system on multicore platform, how to take full advantage of the multicore architecture is very important. Data Partition is usually used to improve the performance of the system. Forthe previous video encoding system, the data partition is fixed and can not be adaptive to the content of the video pictures. Strip-
wise load partitioning scheme is used to partition the video pictures.

efficiently partition to the several cores. The encoding side information such as the bits consumption, the MB type statistic information or the encodingtime on each core can send to the main processor to make a wise strips partition.
Two Considerations can explain how the invention works:
1. Image content is variable in one frame, but the content is continuous for the neiboring pictures.
2. The computation capacity of each core are fixed. So the strips size for each core will influence the performance of the whole system. A balanced load partition can be achived from the coding information on each core which can improve the system performance reasonably.
The mechanism can be easily implemented on the multicore system. A feedback mechanism is established between main processor and multicore processor. The encoding side information...
