I can't understand your concern with sram. You access sram like any other kind of memory.

e.g. you can use sram base address with IOWR/IORD for direct access;

alternatively you can map C variables/buffers (or even an entire memory section) to sram physical addresses.

Example:

int * lcd_buffer = (int*)LCD_SRAM_BASE;

for (i=0; i<num_of_pixels; i++) {

lcd_buffer[i] = <your graphic data>;

}
