28335为浮点DSP ,现在假如我采用两种方法:1.浮点数使用IQmath转换后当定点数计算 2.直接用浮点数进行计算 这两种哪种计算速度快呀? 还有个,说28335可以定点浮点混合编程,但我看到的例子没有这样用的,谁能提供下混合编程的例子吗?学习下

3Q 我其实也不了解怎么个混合编程法,只是看到这句话:
IQmath_f32.lib: This build of the library can be linked with code built with the
--float_support=fpu32 switch. This can be useful for mixing IQmath with native floating-point code on devices with the C28x+FPU.
