Abstract


With the rapid development of information technology , LCD applications has been fully deep into all aspects of people's lives , giving people information exchange has brought great convenience. This research and development of a display system for embedded , FPGA- centric LCD controller. The LCD controller chip DDR SDRAM memory for the display image data stored in the control center FPGA , embedded system through the LCD controller operation , the realization of the LCD display scanning timing settings and data write , thus completing the operation of the liquid crystal display device display . First, this paper discusses the LCD principle , the main achievement of the current domestic and international situation and on the basis of the method , according to the design requirements of this article , this article demonstrates the design of LCD controller's system overall structure . Then on the main hardware chip selection and hardware design are described in detail . Then, the analysis of the main LCD controller module design . Including MCU interface module, a display memory control module , AFIFO module, the address generation module , LCD interface module. Focuses on the design of the working registers , DDR SDRAM controller design , using AFIFO solve asynchronous clock domain data transmission problems , the LCD drive timing signal generation . The PSoC configurable analog and digital functions , memory , micro- controller integrated on a single chip , is truly programmable embedded system chips. Finally , the paper design PSoC-based experimental platform and designed before the LCD controller used in PSoC experimental platform, display the results achieved the expected goals , proved the LCD controller designed in this paper is practical and effective .
