WebNov 1, 2011 · As the computational power of GPUs continues to scale with Moore's Law, an increasing number of applications are becoming limited by memory bandwidth. We propose an approach for programming GPUs with tightly-coupled specialized DMA warps for performing memory transfers between on-chip and off-chip memories. Separate DMA … WebA Nios II core can have zero, one, or multiple tightly-coupled memories. The Nios II architecture supports tightly-coupled memory for both instruction and data access. Each tightly-coupled memory port connects directly to exactly one memory with guaranteed low, fixed latency. The memory is external to the Nios II core and is located on chip.
