So FPU code must always be locked against kernel preemption.
所以FPU代码必须始终被锁定，以防止内核抢占。
Therefore, it is necessary to design high performance FPU.
因此，高性能浮点微处理单元的设计是非常有必要。
The default rounding mode of the FPU is "Round toward nearest."
FPU 的默认舍入模式为“舍入为最接近的整数”。
In addition I recommend Simply FPU because it's an awesome tutorial.
另外我建议只是FPU因为这是一个很棒的教程。
When the kernel is executing floating point instructions, the FPU state is not saved.
当内核在执行浮点指令时，FPU状态不被保存。
FPU mode is another case where the state of the CPU should be protected from preemption.
FPU模式是另外一种CPU应该被保护起来不被抢占的情形。
The type of CPU is detected along with any optional floating-point unit (FPU) and stored away for later use.
然后会为任何可选的浮点单元(FPU)检测CPU的类型，并将其存储起来供以后使用。
If preemption happens here, then upon reschedule, the FPU state is completely different from what was there before preemption.
如果这时发生了抢占，由于重新调度，FPU状态就会与抢占前完全不同。
The SH7205 is a multi-core microcontroller incorporating two SH-2A FPU CPU cores for consumer and industrial applications.
SH7205是一个集成了两个用于消费和工业应用的SH-2AFPUCPU内核的多内核微控制器。
This is true on a FPU-less, JIT-less G1 and a Nexus One with an FPU and the JIT. (Of course, absolute speed difference between those two devices is about 10x for arithmetic operations.)
通常的经验是，在Android设备中，浮点数会比整型慢两倍，在缺少FPU和JIT的G1上对比有FPU和JIT的Nexus One中确实如此（两种设备间算术运算的绝对速度差大约是10倍）
In this verification, the data paths are full covered and the controlling paths are covered with high coverage rate. The simulation result indicates that the design of this FPU meets the demands.
整个验证过程实现了对数据通路的全覆盖，同时对控制通路也有很高的覆盖率，模拟结果表明该F PU的设计满足要求。
