Designing of VGA Character String Display Module Based on FPGA

摘要

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 lowresolution 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.
