DE1 User Manual
A 16-bit word can be written into the SDRAM by entering the address of the desired location,
specifying the data to be written, and pressing the Write button. Contents of the location can be
read by pressing the Read button. Figure 3.5 depicts the result of writing the hexadecimal value
6CA into location 200, followed by reading the same location.
The Sequential Write function of the Control Panel is used to write the contents of a file into the
SDRAM as follows:
1. Specify the starting address in the Address box.
2. Specify the number of bytes to be written in the Length box. If the entire file is to be
loaded, then a checkmark may be placed in the File Length box instead of giving the
number of bytes.
3. To initiate the writing of data, click on the Write a File to SDRAM button.
4. When the Control Panel responds with the standard Windows dialog box asking for the
source file, specify the desired file in the usual manner.
The Control Panel also supports loading files with a .hex extension. Files with a .hex extension are
ASCII text files that specify memory values using ASCII characters to represent hexadecimal
values. For example, a file containing the line
0123456789ABCDEF
defines four 16-bit values: 0123, 4567, 89AB, CDEF. These values will be loaded consecutively
into the memory.
The Sequential Read function is used to read the contents of the SDRAM and place them into a file
as follows:
1. Specify the starting address in the Address box.
2. Specify the number of bytes to be copied into the file in the Length box. If the entire
contents of the SDRAM are to be copied (which involves all 8 Mbytes), then place a
checkmark in the Entire SDRAM box.
3. Press Load SDRAM Content to a File button.
4. When the Control Panel responds with the standard Windows dialog box asking for the
destination file, specify the desired file in the usual manner.
3.4 Flash Memory Programmer
The Control Panel can be used to write/read data to/from the Flash memory chip on the DE1 board.
It can be used to:
?
?
Erase the entire Flash memory
Write one byte to the memory
