SGDMA's alt_avalon_sgdma_construct_mem_to_mem_desc_burst driver

Hi,

I could not find much information about alt_avalon_sgdma_construct_mem_to_mem_desc_burst device driver. I have been using alt_avalon_sgdma_construct_mem_to_mem_desc driver in my applications. Does burst driver has any advantages over regular driver. Even the IP user guide does not describe the use of this driver.

Thanks
