FPGA-based figure signal producing device and method

The invention relates to an FPGA-based figure signal producing device. The FPGA-based figure signal producing device comprises an upper layer interface module, an image parameter caching module, an image parameter conversion module, an external BMP interface module, a logic picture producing module, an image producing control module, an image storage control module, an RGB (red, green and blue) picture output module, an RGB picture timing sequence producing module and a multi-transmission-link low-voltage differential signal transmission module. The FPGA-based figure signal producing device can achieve a function of displaying logic pictures of BMP images and different patterns through an FPGA.
