7.5.39 Write DMA System Source address (lower 32bits)
#define DMA_WRITE_DST_ADR_LO32
0x210
This register holds the lower 32bits of the destination address (byte address !) in system
memory from which the card will transfer data.
Bit
31-0
Function
System memory address (lower 32bits)
7.5.40 Write DMA System Source address (upper 32bits)
#define DMA_WRITE_DST_ADR_HI32
0x211
This register holds the upper 32bits of the destination address (byte address !) in system
memory from which the card will transfer data.
Bit
31-0
Function
System memory address (upper 32bits)
7.5.41 Write DMA Card Memory Destination address
#define DMA_WRITE_DST_ADR_LO32
0x212
This register holds the 32bit destination (byte) address in the cards address space which is
used to select the data source which is written to.
Bit
31-0
Function
Card address space
The address layout is:
DDR4 Memory:
Address 0x0 - 0x7FFFFFFF: DDR4 selected Memory
User DMA space:
Address 0x80000000 - 0x9FFFFFFF: free User DMA space
Address 0xA0000000 - 0xAFFFFFFF: Test-BRAM User DMA space
Address 0xB0000000 - 0xB000FFFF: DAC-RAM
Address 0xC0000000 - 0xC7FFFFFF: SFP1-BRAM User DMA space
Address 0xC8000000 - 0xCFFFFFFF: SFP2-BRAM User DMA space
Address 0xD0000000 - 0xD3FFFFFF: PORT12-BRAM User DMA space
Address 0xD4000000 - 0xD7FFFFFF: PORT13-BRAM User DMA space
Address 0xD8000000 - 0xDBFFFFFF: PORT14-BRAM User DMA space
Address 0xDC000000 - 0xDFFFFFFF: PORT15-BRAM User DMA space
Internal the DAC RAM is mapped into the RAM address space. To write into the DAC RAM,
the
'DMA write enable'
bit must set (refer chapter 7.5.21).
