摘要:
A memory mapping apparatus includes a core/memory selector adapted to select a core from among a plurality of cores, and select a memory from among a plurality of memories, a transfer path allocator adapted to allocate a data transfer path between the core and memory which are selected by the core/memory selector, and a DMA control signal setter adapted to set a signal to be controlled to a DMA Controller which controls a plurality of DMAs corresponding to data transfer paths between the cores and the memories.

Provided are a network load reducing method and a node structure for a multiprocessor system with a distributed memory. The network load reducing method uses a multiprocessor system including a node having a distributed memory and an auxiliary memory storing a sharer history table. The network load reducing method includes recording the history of a sharer node in the sharer history table of the auxiliary memory, requesting share data with reference to the sharer history table of the auxiliary memory, and deleting share data stored in the distributed memory and updating the sharer history table of the auxiliary memory.
摘要:
There are provided a distributed video coding apparatus and method capable of controlling an encoding rate, the apparatus including: an intra-frame encoder encoding a key frame and outputting a bit stream of the encoded key frame; an encoder rate control (ERC) module calculating a bit rate according to motion complexity of a present Wyner-Ziv (WZ) frame by using a correlation between the motion complexity and the bit rate; and a turbo encoder encoding the present WZ frame by the bit rate calculated at the ERC module and outputting the encoded WZ bit stream.
