The code assumes a system clock frequency of 50 MHz and uses a clock divider to generate the 25 MHz VGA clock. You could also use a PLL to generate the clock. PLL configuration varies among FPGAs; for the Cyclone III, the frequencies are specified with Altera’s megafunction wizard. Alte...
的确是这样一个好的verilog代码用多个always语句来分摊一个大的always来执行会使得综合起来更快这也是接前两篇日志说到代码优化的一个值得学习的方面。其次是wire连线很多你要是仔细研究代码不难发现所有的锁存器的连线关系编程者都考虑到了这样就不会平白无故的生成意想不到的寄存器了这也是一个优秀代码的必备要素...
} //相关函数声明 void Si5351Init(void);//初始化Si5351的GPIO void SetPLLClk(uint8_t pll, uint8_t mult, uint32_t num, uint32_t denom);//设置PPL时钟 void SetFrequency(uint32_t frequency);//时钟Si5351时钟频率 void SetMultisynth(uint8_t synth,uint32_t divider,uint8_t rDiv);//...
如下Verilog HDL程序所描述的是一个触发器,对它的描述正确的是( ) module FF(Q,DATA,CLK) input DATA,CLK; output Q; reg Q; always @ (posedge CLK) begin Q <= data; end> A、该触发器对CLK信号的高电平敏感。 B、该触发器对CLK信号的低电平敏感。 C、该触发器对CLK信号的上升沿敏感。 D、该触...
