Study and define if the best approach for the DDR2 memory access using DMA is trough Avalon Memory-Mapped or Avalon Streaming

[rodmarfran]

Considerations:

• Utilize the Avalon Streaming interface may provide interesting advantages, including speed and simplicity, when compared to the Avalon Memory-Mapped, for transmission of big amounts of data in high speed;
• One of the advantages would be utilize a memory access of 256 bits for the DDR2 memory, achieving the memory top speed for a clock of 100 MHz.
