摘要:
依据VGA接口原理,使用SOPC技术实现VGA图形显示.利用一片Altera的Cyclone系列FPGA(现场可编程门阵列)实现准确的时序产生和简单的外围扩展,利用按键和串口控制VGA信号输出模式和图形选择,灰度液晶显示当前VGA信号类型.整个Nios II系统综合可编程逻辑器件原有优势和单片机的优点,可将要显示的测试图形数据直接送到显示器,节省了计算机的处理过程,加快了数据的处理速度,节约了硬件成本.
Abstract:
A ccording to the pr inciple of VGA inter face, ad isplay of VGA w ith SOPC techno logy is designed. Based on one cyclone series FPGA produced by A ltera, an accurate schedule and a sim ple pe riphery a re ach ieved. The key and UART con tro l them ode o f VGA signals output. The LCD d isp lays the sty le of current signa.l The whole N ios II system has exce llences o f PLC andMCU. Using FPGA to design a VGA interface can send the data directly onto the screen for d isp lay, which cuts down the process of PC, thus qu icken ing the speed o f da ta pro cess and sav ing the expense o f the hardwa re.
