The reason is that there are too many floating-point operations in the speech feature extraction process, but these electronic devices do not have strong floating-point operation ability.
原因在于这些电子设备不具备很强的浮点运算能力,而在语音特征提取过程中,却存在着大量的浮点数运算。

Any floating-point operation like addition or multiplication is achieved in a few discrete steps.
任何浮点操作，例如加法和乘法，都可以通过几个步骤来实现。
We have added new API calls that allow applications to do their own CPU benchmarking, or directly report their floating-point operation count.
我们增加了一些新的API调用，允许计算程序进行自己的CPU测试，或者直接报告它们的浮点操作数目。
A physical processor is organized as different execution units at the hardware level, for example, fixed point and floating point operation units.
在硬件级别中，物理处理器是作为不同的执行单元进行组织的，例如定点和浮点操作单元。
