摘要:
A system and a method are provided for improving memory management in a multiprocessor system. A direct memory access (DMA) operation is set up for a first processor. A DMA effective address is translated to a virtual address. The virtual address is translated to a physical address, which is used to access a memory hierarchy of the multiprocessor system.
