ZYNQ核配置流程
1、根据开发板上内存容量配置好DDR3型号，MT41K256M16（单片512MB），后缀任意，位宽根据硬件结构选择16bit（1片）或32bit（2片）
2、配置好MIO的电压，将Bank1的切换为1.8V
3、如需要将程序固化到QSPI，请打开QSPI控制器，管脚选择MIO1~MIO6
4、如需将程序固化到SD卡，请打开SD0控制器，管脚选择MIO40-MIO45
5、如需使用串口打印调试信息，请使能UART1，管脚选择MIO48和MIO49
6、如需通过PS给PL提供时钟，配置PL Fabric Clocks中的时钟频率和个数
7、如需通过AXI-Lite读写FPGA侧的逻辑，使能PS-PL Configuration中的GP Master AXI Interface
8、如需使用FPGA获取PS侧存储器中的内容，使能PS-PL Configuration中的HP Slave AXI Interface
9、更多内容，根据自己需求配置


多帧缓存功能可更改VDMA模块的Frame Buffers
