I tried to use GLCD controller component with 480x272 8bit col., touchscreen, PSOC5-60MHz. It could be very usefull componet, but drawing to display is quite slow. Yes, i could use virtual page, but it spend large amout of expensive SRAM(frame buffer).
I find out in GLCD controller datasheet that writing to frame buffer proceed on in blanking intervals. Try everyone to write to frame buffer between two posedge dotclock using own component for the purpose acceleration? (controll registers+mux or verilog componet)? Eventually any idea to improve draving speed?
You are right. I am using 55ns SRAM as frame buffer. It is too long write cycle to writing data to SRAM between two dotclock edge. Mayby in another desing i try to use 10ns SRAM. It would then be possible to try writing to SRAM like above and GLCD controller component used only for generating TFT signals and screen refreshing.
