文章提出的结构以50%的额外硬件资源，实现基于循环累加的传统DA结构8倍的数据处理速度。

The proposed architecture achieves 8 times throughput rate of conventional DA based on shift-add with 50% extra hardware cost.

但如果你是个程序员，你会认识到他仅仅是个循环：一个累加值，一个累乘。

But if you're a programmer, you'll soon realize it's just a loop: one that sums values, one that multiplies them.

对于不同应力水平作用下的循环时间可计时累加并再现，可为疲劳裂纹形成寿命的预测提供依据。

The circle time under different stress level is accumulated and can be reappeared, so that the basis data is provided to predict surface fatigue crack forming life.

It's going to run through the loop, accumulating the answers, but because I'm subtracting, x it's just going to keep making x more and more negative as it goes along, again it's off into an infinite loop.

它一直在循环，不断的累加答案，这是因为我一直在对x做减法，这使得作为负数的,变的越来越小，又进入一个无限循环了。
