In test.h of the no-OS software, could you explain the why numbers "128*1024*1024" and "0x6000000" are there in these defintions respectively:


#define DDR_BASEADDR          XPAR_DDR_MEM_BASEADDR + 128*1024*1024


#define DDRDAC_BASEADDR      DDR_BASEADDR + 0x6000000



If I change C_MM2S_BURST_SIZE  in AXI_DMA_1  and AXI_VDMA_1 to 32 ( from the default 16), will the above two definitions change?
