| Abstract: | A specific reading or writing(R/W)controller based on page-structure is proposed,which can proceed fast,consecutive or interleaving R/W operations from DVI on Synchronous Dynamic Random Access Memory(SDRAM).The design is built on FP- GA to improve the efficiency of digital video flow re-combination,and accomplishes large-scale frame's buffer and random re- combination.This design can be used in the controlling system of full-color LED display and combined liquid crystal display. |
