Abstract (en)

[origin: WO0051004A1] Methods and apparatus for facilitating a direct memory access in a computing system are disclosed. In one embodiment (Figure), a computing system (100) having a central processing unit (CPU) (114) and a main system memory (106), a DMA engine (110) coupled to CPU (114) performs a first DMA process that identifies a desired data set. Once identified, the DMA engine (110) moves the identified desired data set from a main system memory (106) to a memory segment (115) that is temporally closer to the process or (114) than is the main system memory (106).
