ABSTRACT:
A system and method are provided for setting up a direct memory access for a first processor. The system includes the first processor and a local memory. The local memory is coupled to the first processor. A first direct memory access controller (DMAC) is coupled to the first processor and the local memory. A system memory is in communication with the first DMAC. A second processor is in communication with the first DMAC such that the second processor sets up the first DMAC to handle data transfer between the local memory and the system memory. The second processor is interrupted when the first DMAC finishes handling the data transfer.
