SRAM Loading from PROM

Hi all,
Is is possible to load initial contents to the external SRAM if Xilinx Spartan-3 from PROM?
I am using the SRAM to interface a VGA monitor. What I'm doing is saving every pixel color on the SRAM, and then, every pixel color is read from SRAM.

I will use it to display the results of a transformation, but I also want to display some characters, lets say, my name, so, in the way I am currently doing it, characters position are saved in ROM, therefore, this would waste a lot of FPGA resources.

So, I was wondering whether I could load characters from PROM directly to the SRAM, that way, I wouldn't use so many resources from FPGA.

Thanks in Advance,

Re: SRAM Loading from PROM

if you are reffering to the xilinx configuration prom , then yes
you can add your information in the end of your bit file, when the configuration is ended you can use the configuration pins as i/o and keep on reading the prom, i once did it by myself and it worked ! then all you need is to copy this bit to the SRAM. read some application regarding the bit file format in your prom.
