DEVICE AND METHOD FOR EXECUTING A DMA TASK

摘要

A method (700) for executing a DMA task, the method includes receiving (750) a request to execute a DMA task; the method characterized by including: defining (710) inter-buffer jumping points at substantially an end of one or more dimensions of each multidimensional buffer out of a plurality of multidimensional buffers; and executing (770) multiple DMA sub-tasks, wherein the executing includes jumping between buffers at the inter­buffer jumping points. A device (90) that includes at least one memory unit (94, 93) and a DMA controller (100) adapted to access the memory unit; the device (90) is characterized by being adapted to implement multidimensional buffers within the at least one memory unit (94); wherein the DMA controller (100) is adapted to execute multiple DMA sub-tasks, wherein the execution comprises jumping between buffers at inter-buffer jumping points; and wherein the inter-buffer jumping points are defined at substantially an end of one or more dimensions of each multidimensional buffer out of a plurality of multidimensional buffers.
