Parameter

Value

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.
