断言,是宏,而非函数。assert 宏的原型定义在<assert.h>(C)、<cassert>(C++)中,其作用是如果它的条件返回错误,则终止程序执行。可以通过定义NDEBUG来关闭 assert,但是需要在源代码的开头,include <assert.h>之前。 使用 代码语言:javascript 代码运行次数:0 ...
For instance, instead of calling a divide instruction in a CISC device, you would have to do a series of subtractions to accomplish a division using a RISC device. This 'disadvantage' was offset by price and speed, and is completely irrelevant when you program with C since the complier ...
FIFO FIFO是英文First In First Out 的缩写,是一种先进先出的数据缓存器,他与普通存储器的区别是没有外部读写地址线,这样使用起来非常简单,但缺点就是只能顺序写入数据,顺序的读出数据,其数据地址由内部读写指针自动加1完成,不能像普通存储器那样可以由地址线决定读取或写入某个指定的地址。 FIFO多用于......
