This thesis deals with controlling a color graphic LED display using an FPGA. The first half of the theoretical part of this paper describes the properties of the used FPGA, the data source and a principle of controlling an RGB LED display. The second half describes an implementation of pulse width modulation and binary code modulation which enables the control of brightness of the display and of color depth of every sub-pixel. The practical part on the other hand describes the designing and the implementation of this module in the VHDL language. Then it explains the transfer of image data from Blackfin processor to the memory via PPI interface, the subsequent process of reading data from the memory, conversion of the data to a serial format and finally it describes the process of sending the data to the LED controller. The module was realized on the Digilent Atlys development board equipped with the Spartan-6 FPGA and was tested on a 32x20 light panel for the firm Ing. Ivo Herman, CSc.
