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。

Similarly, on platforms without native support for fixed-point or double-precision floating-point Numbers, implementations must emulate these types.

类似地，在没有本地定点或双精度浮点数支持的平台上，实现必须模拟这些类型。

However, since the fixed-point calculation maybe cause cumulative quantization error, the convergent performance of fixed-point equalizer is not better than that of floating-point equalizer.

但由于定点数运算会引起量化累积误差，均衡器的收敛速度比浮点数运算均衡器的收敛速度要慢，收敛后的稳定性也较差。
