i'm trying to speed up microblaze write operations to do some graphics
I attached a BRAM to the AXI interconnect and a DDR memory controller.
Writing to the DDR or the BRAM takes the same time, is it normal?
I thought that writing in the BRAM was much faster!

in a c program, i use a for cycle to initialize some memory locations, with a timer i measure the time to get the for cycle completed
I have to draw text strings, i thought that if i put the font in the BRAM the write process was much faster, but it wasn't
i need a way to draw graphics much faster!
to delete it i use a CDMA that blanks all the graphic memory buffer and it's ok
