Description
Maximum packet length
10–1024, Default = 10 Select the maximum packet length as a
number of symbols. The minimum value is
10 because this is the size of an Avalon-ST
control packet (header included). Extra
samples are discarded if packets are larger
than allowed.
Note: You must select double or triple-
buffering mode if you want to
control the buffering of non-image
data packets.
Use separate clocks for the
Avalon-MM master interfaces
On or Off
Turn on to add a separate clock signal for the
Avalon-MM master interfaces so that they
can run at a different speed to the Avalon-ST
processing. This decouples the memory speed
from the speed of the data path and is
sometimes necessary to reach performance
target.
Avalon-MM master ports width • 16
• 32
• 64
• 128
• 256
Specify the width of the Avalon-MM ports
used to access external memory when you use
double-buffering or triple-buffering.
Note: Available only when you select
Double buffering or Triple
buffering with rate conversion.
Read-only master(s) interface
FIFO depth
16–1024, Default = 64 Choose the FIFO depth of the read-only
Avalon-MM interface.
Read-only master(s) interface
burst target
2–256, Default = 32
Choose the burst target for the read-only
Avalon-MM interface.
Write-only master(s) interface
FIFO depth
16–1024, Default = 64 Choose the FIFO depth of the write-only
Avalon-MM interface.
Write-only master(s) interface
burst target
8–256, Default = 32
Choose the burst target for the write-only
Avalon-MM interface.
Base address of frame buffers
Any 32-bit value,
Default = 0×00000000
Select a hexadecimal address of the frame
buffers in external memory when buffering is
used.
The total memory required at the specified
base address is displayed under the base
address.
Note: Available only when you select
Double buffering or Triple
buffering with rate conversion.
