| 摘 要： | 根据IEEE754／854标准，微处理器浮点单元的异常类型繁多，产生异常的原因和处理方式也比较复杂。因此浮点单元的设计中经常面临异常难以捕获的问题。本文提出一种高精度、高指令密集度开放式异常处理方法，保证了异常检测的完备性，减少了面积和功耗，加快了指令执行速度。 |
| 关 键 词： | 浮点异常 松耦合关联 异常处理 |

| Abstract: | According to the IEEE754/854 standard, there is a diversity of microprocessor floating-point unit exceptions, and the exception generation and processing mechanism are also complex. For these reasons the exceptions in the floating-point unit are often difficult to capture. In this paper an open exception processing mechanism with high-precision and high-instruction-density features is presented. With this mechanism, the completeness of exception checking is guaranteed, and the area-power and instruction processing speed also benefit. |
| Keywords: | floating-point exception loose-coupled association exception processing |
