Detection of miscalculation caused by precision degradation

为了实现对浮点数计算精度退化的有效检测，我们开发了一种具有两个或多个浮点运算单元的向量协处理器，该协处理器具有精度退化检测功能。And we investigated调查that it worked工作correctly正确.此外，我们比较了工作负载的执行周期数，这实际上会导致精度下降，与传统的处理器。因为我们的向量处理器可以执行约1/5的执行周期，我们实际上可以使用这个系统作为一个原型系统。

To achieve the efficient accuracy degradation detection on floating point number calculation, we developed a vector co-processor that has two or more floating-point arithmetic units with accuracy degradation detection function. And we investigatedthat it worked correctly. Moreover, we compared the number of execution cycles of the workload, which actually causes accuracy degradation, with a conventional processor. Because our vector processor can execute by about 1/5 number of execution cycles, we can practically use this system as a prototype system.
