The processor core processes data stored in a memory and executes instructions using the memory. The FIFO receives streaming data and outputs the streaming data to the memory. The arbiter module, in response to the FIFO not being filled to a predetermined threshold, allows the processor core to access the memory at a higher priority than the FIFO to permit the processor core to process data including any streaming data stored in the memory, and to execute instructions using the memory. The arbiter module, in response to the FIFO being filled to the predetermined threshold, allows the FIFO to access the memory at the higher priority than the processor core to permit the FIFO to output the streaming data, without having the FIFO overflow, to the memory.
