Abstract
Provided are an apparatus, a method, and a data processing element (DPE) for efficient parallel processing of multimedia data. The DPE includes: a memory routing unit (MRU) comprising a shared memory page shared by the DPE and DPEs that are adjacent to the DPE, and a shared page switch selectively connecting the shared memory page to the DPE and the adjacent DPEs; and a data processing unit (DPU) comprising a virtual page for connecting the DPU to the shared memory page, and a dynamic remapper assigning the shared memory page to a DPE according to conditions that a series of tasks for processing multimedia data are performed in the DPE and the adjacent DPEs, and controlling the shared page switch according to the assigning. Accordingly, multimedia data can be efficiently processed in parallel by mapping a temporal and directional shared memory between DPEs.
