Altera_ForumDMA is Avalon-MM (memory map) and SGDMA is Avalon-ST (streaming memory)
memory-to-memory (onchip to sdram, sram to sdram) stream-to-memory (buffer array to sdram, buffer to sram) memory-to-stream (sdram to buffer array, sram to buffer). You should read more about Avalon Interface Spec. Sean
