Student tutorial implementing a dual screen buffer for an LCD display using an FPGA

This paper describes a laboratory exercise where the students are given the task of implementing a complete graphics system in an FPGA, for direct connection to an LCD module. The first part of the system is charged with generating a series of images that are to be displayed on the LCD. The graphics controller utilizes a dual screen buffer where one image is transferred to the LCD, while the other off-screen buffer is updated by the controlling module. The final part controls the transfer of the screen buffer to the LCD.
