软件流水是一种开发循环程序指令级并行性的技术，它通过并行执行连续的多个迭代来加快循环的执行速度。

Software pipelining is a loop scheduling technique which extracts instruction level parallelism by overlapping the execution of several consecutive iterations.

多年来，处理器制造厂商在不断提高时钟速度和指令级并行性，因此单线程代码不需要修改就可在新的处理器上更快运行。

For years, processor makers consistently delivered increases in clock rates and instruction-level parallelism, so that single-threaded code executed faster on newer processors with no modification.
