help required in increasing the refreshing of display ram

[harilcd]

hai iam new to this forum, and iam glad to see so many good people out there to share their knowledge.

Well i have a lcd module with built in controller(LC7981) +memory
192x128 dot matrix lcd

the microprocessor is taking too much time inorder to dump the display information to the lcd as a result of which the processors performance is degraded. (though i refresh display ram with new display data once per sec==>tooo bad)
The increased time cause:
(1)i dont have direct access to sram, i have to access sram only throu' controller after passing suitable command words. (This has to be done for every 8 pixel of information) (192x128)/8 words has to sent. as i also have to take care of control signal i cannot use dma


If not is their any solution to solve this problem

Are there lcd modules available in the market which allows dumping of display information directly to sram rather than throu' controller (assuming sram to be dual ported ) their by reducing the load on the processor

I would be very happy if i could get a solution to increase the refreshing of display ram with new display buffer information with our affecting the processor performance
