Parameter
Value
Description
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 number of frame buffers and the total
memory required at the specified base
address is displayed under the base address.
Align read/write bursts with
burst boundaries
On or Off
Turn on to avoid initiating read and write
bursts at a position that would cause the
crossing of a memory row boundary.
Table 14-3: Frame Buffer II Parameter Settings
Parameter
Value
Description
Maximum frame width 32–4096,
Default =
4096
Specify the maximum frame width in pixels.
Maximum frame
height
32–4096,
Default =
2160
Specify the maximum progressive frame height in pixels.
Bits per pixel per color
plane
4–20, Default
= 8
Select the number of bits per pixel (per color plane).
Number of color planes 1–4, Default
= 3
Select the number of color planes that are sent in sequence.
Color planes
transmitted in parallel
On or Off
• Turn on to transmit color planes in parallel.
• Turn off to transmit color planes in series.
Pixels in parallel
1, 2, or 4
Specify the number of pixels transmitted or received in parallel.
Interlace support
On or Off
Turn on to support consistent dropping and repeating of fields in
an interlaced video stream.
Note: Do not turn on this parameter to double-buffer an
interlaced input stream on a field-by-field basis.
Use separate clocks for
the Avalon-MM
master(s) 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(s)
local ports width
16-512,
Default = 256
Specify the width of the Avalon-MM ports used to access
external memory.
Write FIFO depth
16–1024,
Default = 64
Select the FIFO depth of the write-only Avalon-MM interface.
