Supporting Efficient Synchronization in Multi-core NoCs Using Dynamic Buffer Allocation Technique

This paper explores a dynamic buffer allocation technique to guide a distributed synchronization architecture to support efficient synchronization on multi-core Network-on-Chips (NoCs). The synchronization architecture features two physical buffers to be able to concurrently queue and handle synchronization requests issued by the local processor and remote processors via the on-chip network. Using the dynamic buffer allocation technique, the two physical buffers are dynamically allocated to form multiple virtual buffers in order to improve buffers´ utilization. Experiments are carried on to evaluate buffers´ utilization.
