I am new in altera platform. I was reading the DMA functionalities. I read data sheet available for SG DMA and nirmal DMA controller, but I could not find few basic specification of DMA like their throughput and Clock-wise description of each signal. IS there any other datasheet available for those DMA?
Those signals are standard Avalon-MM bus. Look at the section "The Master Read and Write Ports" on page 26-3. It points to the Avalon bus interface specification.
