“pass-through” level of the gate would be when the value of the if clause is true, i.e. gate = 1. This is read “if gate is true, the din is fed to latchout continuously.” Once the if clause is false, the last value at latchout will remain and is independent of the value...
二进制编码(Binary)、格雷码(Gray-code)编码使用最少的触发器,较多的组合逻辑,而独热码(One-hot)编码反之。独热码编码的最大优势在于状态比较时仅仅需要比较一个位,从而一定程度上简化了比较逻辑,减少了毛刺产生的概率。由于CPLD更多地提供组合逻辑资源,而FPGA更多地提供触发器资源,所以CPLD多使用二进制编码或格雷码...
