Designing of VGA Character String Display Module Based on FPGA

VGA (video graphics array), as a standard interface, has already been applications widely. There are a lot of FPGA-based VGA controller designs on which, however, there are still larger defects such as low-resolution display and the Chinese characters display modules occupying large resource. Therefore, we propose the use of VHDL as a logical means to describe the completion of high-resolution VGA control module and a resource-conserving string display module design, and provide two main modules of designing ideas and logic diagrams. And experiments show that: while the Chinese characters ensure a high-resolution display, the storage resources needed by the display decreased significantly.
