Access and Optimization of OSD Based on FPGA

Abstract:

Based on jumping in ten digits, optimization of OSD module in FPGA storage and read. the Chinese character OSD information superimposed on the video, take a transparent overlay mode. OSD information is stored in the FPGA mostly, and communicates with the SRAM, through the OSD information into the SRAM, the program reads the character dot matrix information from the SRAM to improve the function of OSD and beautify the superposition effect.
