Popis: | To solve the localization that VGA display system based on computer or ASIC lacks portability and modification,a novel VGA display system to display any characters and images was designed under PS/2 keyboard control,which is based on user custom kernel SOPC technology.In FPGA,a 32-bits NIOS Ⅱ hardcore was built,main program was compiled with C language,and a AVALON BUS was used to connect the external drive controller and basic PIO interface,combined with VGA controller which composed by VGA timing module and buffers,the software part was completed through the above.Hardware platform is consisted of basic hardware circuit,external memory chips,PS/2 keyboard,VGA interface and UART circuit.The system finally achieved the migration of SOPC kernel and function of displaying character and image on CRT monitor under PS/2 keyboard control. |
