这是三元运算符.这是if语句的简写

That's a ternary operator. It's shorthand for an if statement

格式:

condition ? if true : if false

示例:

tone[23] ? clkdivider-1 : clkdivider/2-1

翻译成类似的东西(语法不正确，但我想您会理解的):

Translates to something like (not correct syntax but I think you'll get it):

if tone[23] is 1, counter = clkdivider-1
else counter = clkdivider/2-1

以下是使用if语句和三进制的 2比1 MUX的两个示例运算符.

Here are two examples of a 2 to 1 MUX using if statement and ternary operator.
