* DMA parameters (``dma_maxbytes``, ``dma_buswidth``, ``mem_pipeline``): Gemmini implements a DMA to move data from main memory to the Gemmini scratchpad, and from the Gemmini accumulators to main memory. The size of these DMA transactions is determined by the DMA parameters. These DMA parameters are tightly coupled with Rocket Chip SoC system parameters: in particular ``dma_buswidth`` is associated with the ``SystemBusKey`` ``beatBytes`` parameter, and ``dma_maxbytes`` is associated with ``cacheblockbytes`` Rocket Chip parameters.
