Six LED dynamic display and six keys keyboard circuit have been designed, which uses the complex scheduling function of FPGA combined with the serial input / parallel output shift registers. 利用FPGA实现复杂时序的功能,同时结合使用串行输入/并行输出移位寄存器,设计了6位LED的动态显示和6个按键开关的键盘电路。
Both the output voltage controller and voltage controller are designed so that several identical power modules can work with serial input and parallel output mode, ensuring the output voltage-sharing and the wide range are adjustable. 通过对输出电压控制器和均压控制器的设计,使多个模块在输入并联输出串联的连接方式下工作,保证输出电压均压并且电压宽范围输出可调。
Based on the jointed test action group ( JTAG ) protocol, instructions and scan chain were introduced. With test access port ( TAP ) module exchanging serial input with parallel output, register files and random access memory on chip were read or written in parallel. 在JTAG接口协议的基础上,增加指令和扫描链,同时通过测试访问端(TAP)控制把串行输入转换成并行输出,并行访问数字信号处理器的寄存器文件和片上存储器单元,实现嵌入式模拟器。
The accuracy of theoretical simulation design method is tested with Saber software. Finally, in order to obtain wide high voltage output, a converter control strategy is proposed by a combination of serial input and parallel output which a suitable for the applications of high output voltage. 利用Saber软件仿真,验证理论设计的正确性。最后,为了获得宽幅高电压输出,提出一种适合高压输出应用场合的输入并联输出串联组合变换器的控制策略。
