Read from a File

To read the contents of a file and load it to the DDR SDRAM, follow these
steps:

1.

Click Load File.

2.

Browse to sample.txt located in the control_panel directory and
click Open. This step instantiates the DDR SDRAM controller and
loads the text contents into the DDR SDRAM. Notice that the Data

1.

Click Save File.
